Midnight Express: Eric Glaser on Arid Pickup Locations

By |2026-10-13T16:59:44+00:00October 23, 2025|Articles, Blog, Boat Builders, Boat Stories, Center Consoles, Performance Boats|

Where does the water remain after the bilge pump stops? On a boat with several separate compartments, that question needs more than one answer. Arid supplies Midnight Express, and Eric Glaser’s conversation with Alfred Baurley explains how the builder approaches collection points below deck.

Midnight Express builds performance center consoles in Miami and emphasizes customization. The interview brings that idea into an area an owner may see only through an access hatch: the placement of a central drying unit and the lines serving it.

Start with the compartments

Glaser describes mounting the central unit in the rear bilge, with pickups in the rear and mid-bilge. Depending on the customer’s needs, he says, a collection point may also be fitted near the bow thruster where water can remain.

At the time of the interview, Glaser described Arid as an option offered across the builder’s models. The conversation does not identify one particular Midnight Express model, and a buyer should confirm the equipment and pickup plan for the boat being ordered. The useful detail is the approach: choose collection points for the spaces that need them.

Make the pickup plan easy to follow

When reviewing a build or an existing installation, ask for a simple compartment map. Mark the central unit, each pickup and the access point used to inspect it. If the bow-thruster compartment is included, identify its line rather than assuming it is covered because a system is fitted elsewhere.

Then consider service access. Can someone reach the pickup to inspect it? Can the tubing route be followed without moving unrelated equipment? A short walkthrough with the installer can turn an equipment list into something the owner and service team can use.

The Phenom 34 walkthrough offers another example of why separate bilge areas deserve individual attention. The Hylas H57 conversation adds another consideration: where operating equipment sits in relation to the living space. Both are useful comparisons, rather than specifications for a Midnight Express.

Keep the jobs of the two systems clear

Arid addresses residual water through pickups connected to a central unit. Conventional bilge pumps retain their own job, and a new source of water still needs investigation. Our guide to how Arid works shows the collection and discharge process.

For the owner, the takeaway from Glaser’s account is concrete: understand which compartments are served, how to reach the equipment and what was specified for this boat. Those details belong in the handover as much as the controls at the helm.

For a brief introduction, watch the Midnight Express interview Short.

The Midnight Express interview

Alfred: Eric, can you tell me a little about your experience—how the Arid Bilge System has worked across your Midnight Express boats?

Eric: Yeah, absolutely. We offer Arid Bilge Systems across all of our models. It helps keep the bilges dry and clean, so you’re not worried about all the corrosion and the mess you’d normally find down there. It’s a great option. You guys have a bunch of different versions—some different power supply options—and it works for us depending on which way we’re powering the boat.

Alfred: Where is the system mounted on the boat?

Eric: We mount them in the rear bilge of the boat on every model.

Alfred: What locations does it vacuum from?

Eric: So we do one in the rear bilge, one in the mid-bilge, and then depending on what the customer asks for, sometimes we do one up by a bow thruster, where it might catch a little bit of water—just to help keep everything dry in those areas too.

Alfred: And this has improved your boats by keeping everything nice and dry versus having a wet, moldy environment—especially when you think about protecting your Seakeeper, your generator, and all the sensitive components that are down in those compartments.

Eric: Of course. It’s all good things. Water messes everything up, and we’re in a wet environment on a boat—so it just makes sense to dry it out.

Alfred: Eric, I really appreciate your time.

Eric: No problem. Thanks for making a great product. Keep it up.

Chuck Casagrande on Drying His 40-Foot Catamaran

By |2026-10-15T01:37:58+00:00October 17, 2024|Articles, Boat Stories|

Chuck Casagrande’s 40-foot catamaran was an older boat rebuilt around the way he wanted to use it. The refit included custom equipment, engineering work and a less visible priority: dealing with moisture below deck.

In this boat-show interview with Alfred Baurley, the SeaSucker owner describes pickups in both hulls and the dampness he had seen around wiring and connections. He also makes an important distinction: a leaking fuel tank had to be replaced. Arid addressed the residual water that remained afterward.

A catamaran needs a survey of both hulls and the separate places where water collects. Start with our guide to finding hidden wet zones, then read how persistent dampness can contribute to corrosion below deck. Neither drying nor cleaning replaces repairs to a leaking tank or damaged equipment.

Chuck’s 40-foot catamaran refit



Alfred: Chuck Casagrande. He’s given us a testimonial review about the Arid Bilge System on his personal boat. He sells thousands of Seasuckers, and I wanna hear from him directly. What was your experience like?

Chuck: It was good. We’ve been working with you probably 4 or 5 years. And we put that system in, and that was great. It’s a big difference. I have a big boat. I have a 40-foot Catamaran. It was an older boat that we bought and we redid. And initially, we had some problems with the tank. We had moisture issues down below. It was water everywhere, even fuel for a while. Keeps it dry. We’ve got pucks in the back, and we’ve got pucks in the front. Since we have a Catamaran, you’ve got separate system on both sides. So the tubes will run over to the other pontoons forward and backwards. So it’s a pretty big system, and it works beautiful.

Alfred: First of all, you have a series 4, how many zones on that?

Chuck: But there’s, like, 4 something. I’m not technical on the actual product, but it works. It’s great.

Chuck: [At Seasucker] we’ve got a full machine shop, injection molding, tons of engineers. So I got an older boat, and we built it up from scratch, and a lot of custom stuff on there, but they really helped us fix that part of it.

Alfred: What do you mean by you have your engineers work on the boat directly?

Chuck: Well, I also have the engineers. I drag them in from Seasucker sometimes to the boat. So people laugh about a little bit. Sometimes it’s a Chuck’s boat day. Some special work on the boat together. We put a diving board on the boat. We’ve got a full de-sal system, 500 pounds of ice a day. It’s got a bathroom, sleeps 4. We’ve added all these things to it, so engineers are engaged here and there to make it work.

Alfred: Right. So did you experience any sort of humidity? That happens on Catamarans in the first place. Did you experience any odor?

Chuck: We had a ton. I mean, like I said, we had a fuel issue. So we had a big smell with the tank leaking. We had to replace the tank. But besides that, the boat still had water down there, which I didn’t like. When you have that moisture just sitting down there with all the hatches closed, you’ll see a film of moisture on all the electronics, on all the wires. Everything corrodes quicker then, so then you’re replacing stuff every year or two. With this system, everything stays dry down there. If I see it’s dry, I know my wires, my connections, everything’s gonna last a long time, and that’s what this system helps you do.

 

Moisture was part of the maintenance picture

Chuck’s story centers on the equipment sharing those below-deck spaces. He wanted to see less standing water and dampness around electrical connections after investing in the boat’s refit. His account describes the results on this particular installation.

For the process behind those pickups, see how Arid works.

Hylas Yachts: Kevin Wensley on Dry Bilges

By |2026-10-13T16:59:44+00:00August 23, 2024|Articles, Blog, Boat Builders, Boat Stories|

A cruising yacht is also a place to live. The cabins and salon get most of the attention, but the compartments beneath them deserve a place in the conversation. Arid supplies Hylas Yachts, and Kevin Wensley’s interview with Alfred Baurley aboard an H57 explains that relationship through the practical details of life below deck.

The Bill Dixon-designed Hylas H57 is a bluewater sailing yacht with interior customization among the builder’s priorities. For an owner planning extended time aboard, the equipment behind that interior matters alongside the layout itself: where it operates, which spaces it serves and how it can be maintained.

Small amounts of water still need a plan

Wensley gives a specific example from commissioning: rain entered while the mast was being stepped. He says the compartment was dry when he checked it before the interview. He also discusses water returning through bilge-pump plumbing after a pump stops. These are observations about the yacht and installation being discussed, rather than a promise that water can never enter a Hylas.

Arid’s role is to remove residual water alongside the yacht’s conventional bilge pumps. The collection and discharge cycle explains how low-point pickups serve a central unit. Investigating a new leak and caring for existing pumps remain part of owning the boat.

Fit the equipment around the living space

On the installation Wensley describes, the central unit sits in the insulated engine compartment. He explains that this keeps operating noise away from the living area. Collection points serve the main bilge below the salon and an aft area near the steering equipment.

That is useful information to carry into a handover. Ask to see each pickup, follow its tubing route and identify the access needed for cleaning and service. Keep that map with the installed model’s manual. It gives the next person caring for the yacht something more useful than a general instruction to check the bilge.

See the water-routing animation

Illustrative Arid water-routing animation. Actual equipment placement and pickup locations vary by vessel and installation.

This silent animation shows pickups in separate low areas connected by tubing to a central Arid unit, with collected water moving through a discharge line.

Carry the layout into the ownership conversation

Before agreeing an installation, walk through the boat with the people who will maintain it. Can the unit be reached without dismantling unrelated fittings? Which floor panels reveal the collection points? Where will electrical specifications and service instructions be kept?

The boats differ, but the placement question also appears in our Midnight Express conversation with Eric Glaser. Our Albemarle conversation with Keith Privott considers the care given to finished bilge spaces. On the H57, Wensley makes the placement question personal: the machinery has to work within a yacht that people sail, clean and live aboard.

Edited interview highlights from Hylas Yachts

This summary draws on the conversation aboard the H57. Watch the video above for the complete interview.

The small amount a bilge pump leaves behind

Wensley describes a yacht designed to stay dry, while acknowledging that some water still reaches the bilge. His example is rain entering while the mast was being stepped during commissioning. When he checked the compartment before the interview, he found it dry.

The discussion also covers water that can return from bilge-pump plumbing after a pump stops. For Wensley, removing that residual water is part of keeping the spaces below deck pleasant to use. He connects the condition of those compartments with the smell and overall feel of the yacht.

Place equipment around the way people live aboard

On this installation, the central Arid unit sits in the insulated engine compartment. Wensley explains that the placement keeps operating noise away from the living space. He describes pickups serving the main bilge beneath the salon and an aft area near the steering equipment.

Those details make the installation concrete: a central unit needs a suitable location, and the collection points need to reach the areas where water remains. Access for inspection and service belongs in that planning, too.

Installation support and electrical planning

Wensley speaks positively about communication between Arid, the Hylas factory and the service team. He describes support with installation details and questions from owners, alongside the wider service relationship Hylas maintains with its customers.

The conversation also touches on electrical demand and the resources available aboard a sailing yacht. Those comments concern the equipment discussed in this interview. Use the manual for the installed model when checking current electrical specifications and maintenance requirements.

The recurring point is comfort backed by practical details: where water collects, where equipment is fitted and how the people caring for the yacht can reach it.

Albemarle Boats: Keith Privott on Bilge Fit and Finish

By |2026-10-13T16:59:44+00:00June 13, 2024|Articles, Blog, Boat Builders, Boat Stories|

Keith Privott’s description of a finished bilge is easy to picture: open the engine-room hatch and find clean, bright surfaces, with the equipment and workmanship on view. Standing water becomes conspicuous in a space built to look that way.

Arid supplies Albemarle Boats. In our interview published in June 2024, Privott discusses Arid as one component in the builder’s broader approach to materials, finish and owner maintenance. His perspective is particularly useful for someone who enjoys looking after a boat and wants to understand the systems beneath its polished exterior.

A finished bilge needs ongoing care

Albemarle’s official history records its incorporation in 1978 and its roots in Edenton, North Carolina. Privott brings that boatbuilding story down to practical details. He describes owners who take pride in maintenance and explains how water left on a finished, gel-coated bilge can affect its appearance.

His observations are an argument for paying attention to the compartment after delivery. A good finish gives an owner something worth caring for; inspection and routine maintenance continue throughout ownership.

Where residual-water removal fits

A conventional bilge pump may leave shallow water below its intake, and separate low points may not drain to the pump. Arid collects residual fluid from the areas served by its pickups. That is a specific job within the boat’s maintenance routine.

It does not replace the conventional bilge pumps or fix a leak. If water returns, investigate the cause. If a stain remains after the compartment dries, assess the surface and follow the builder’s care guidance. Removing water and restoring an existing finish are different tasks.

Our guide to how Arid works explains the collection process. The water-routing animation illustrates the process; actual equipment placement depends on the boat.

Questions to bring to the boat

Ask which low points an installation will serve and whether the pickups are accessible for maintenance. Check that the central unit and its connections can be reached without turning a routine inspection into a major dismantling job. Confirm current equipment availability for your particular Albemarle with the builder or dealer.

Watch the original Keith Privott interview for his full account, or watch the short version. His comments describe the builder’s approach at the time of that conversation.

For a crew’s perspective on water left after cleaning, read Scout’s conversation with Josh Slayton. For a practical look at collection-point placement, see Eric Glaser’s Midnight Express interview. These are different boats, but both conversations make the below-deck questions easier to ask.

Albemarle Boats: Keith Privott’s interview

Alfred: Albemarle has been around for many years, and they produce the highest possible quality of boats, highest possible quality finish, and they want to see their boats last. That’s where the Arid Bilge System delivers that clean, dry, fresh boating experience. Keith, you mind telling us a little about that?

Keith: Yeah, like you said, it’s from the maintenance standpoint, for the longevity of the boat, we try to use the top quality materials in the boat. Everything from even hardware: instead of using a typical 316 stainless, we’ll use chrome-plated stainless where possible. So, you’re always trying to upgrade materials and use the best quality, and part of that is to keep that boat looking as good and functioning as well.

Alfred: Albemarle has been around for how long now?

Keith: Forty-five years.

Alfred: All right. Tell me a little bit about your boats.

Keith: So, we are primarily offshore fishing boats. We do build some smaller dual consoles, but our customer focus tends to be more on the hardcore fishing guys. We have typically a little bit heavier construction. We like to think we pay a lot more attention to detail and just a little bit more refined boat.

And that’s how your system comes into play as far as what we offer. We have customers that really pride themselves on maintaining boats, and a lot of those customers do the maintenance themselves. It’s just a labor of love for them to tinker around on a boat and keep it clean and upgrade everything they can.

Alfred: You would say that the Arid Bilge System really helped improve your line of boats?

Keith: I’d say so. I mean, it’s one of those systems that you don’t have to think about it. As a builder, you like systems that you can put in, and if you don’t hear back from them, that means it’s functioning correctly, and it’s not an issue. We use so many components on the boat. We deal with thousands of vendors and at the same time, we try to get the best quality you can get. The idea is to offer an experience where they don’t have to worry about replacing components or fixing. They can enjoy the boat instead of working on the boat. But also just the appearance and the odor, I mean, it just plays into everything we’re trying to do and offer better boating experience–less hassle, and more enjoyment out of the boat that they’re paying us to build.

Alfred: So one of the point with the Arid Bilge System is, we go in and make everything completely bone dry, and when it’s a dry and clean environment, it’s a happy environment in your boat. So you would say that it coexists very well in that sort of fashion for you?

Keith: Absolutely. We do finished bilges, obviously. It’s almost like it’s going to a next level over the last 20 years in particular, where it’s not the utilitarian, “let’s go out there and just fish and hammer the fish every day and come back and wash the boat down.” It’s like everything’s become more refined, and the expectations now are that you open an engine room and you’re almost dazzled by how everything is just so clean and white and well appointed. So we’ve really gone down that route, particularly in the last ten years, to pay more attention to the level of fit and finish, even down in the bilges. So when you open an engine room, everything’s nice and clean and bright, and you look down, and you don’t see puddles of water in the bilge, you don’t have any stain. We finish the bilges. A finished gel-coated bilge, if you let water sit there for weeks at a time, you start to see a little staining here and there.

Overall, it just keeps the appearance of the boat up. It keeps the maintenance at a minimum. It’s kind of a no-brainer for us to put the system on the boat. Like I said, the boats are becoming more and more refined. The systems are becoming more complicated. Everything’s becoming integrated now, so we have to grow with the business and with the technology. But at the same time, the core principles are still there of “build it stronger than it needs to be, build it for the worst-case scenario, and hope for the best.” And at the end of the day, regardless of what kind of conditions you get caught in, you’re going to come home with the same boat structurally and aesthetically. It’s going to hold up over time. And we do that by the techniques we use, building more glass than we should. Our boats are typically heavier than most, and that’s because of the materials we use. We’ve learned the construction techniques over the years, glassing everything back together and creating almost like a unibody construction where nothing moves unless everything moves. Through experience, we’ve figured out what holds up on a terrible day offshore, and we build them for that scenario.

Fast forward to today, and our largest boat is 53′  while our smallest is 25′. We have a pretty broad range of product, but it’s all dedicated to being offshore-capable, holding up over time, and being the same boat even in 20 years that it was the day it was built as long as it’s maintained and taken care of.

Alfred: Thank you so much, Keith, for giving us a short testimonial and talking about your boats. It’s been an honor, and thank you so much for the business, and I appreciate working with you.

Keith: Sure. Thank you for providing a good product. It contributes to ours.

Bilge Paint and Standing Water: J.P. Ferris of Axalta

By |2026-10-10T22:12:54+00:00May 27, 2024|Articles|

What happens when bilge paint stays underwater? In a boat-show conversation, J.P. Ferris of Axalta Coating Systems explained why the answer depends on the coating, its preparation and the length of exposure.

At the time of the interview, Ferris brought a 35-year painting career spanning boats, yachts, aircraft and other applications. The discussion focused on two finishes found in bilges: urethane coatings and gelcoat.

Urethane coatings and prolonged immersion

“Urethane coatings, if left submerged, can develop blisters and begin to delaminate,” says J.P. Water beneath the coating can lead to bubbling, flaking and peeling.

Asked how quickly that could happen to a fresh coating, Ferris described a range from a week to months, depending on preparation, film thickness and time submerged. That was a conditional explanation, not a fixed lifespan for every paint system. Repairing damaged paint can involve removing the affected coating, preparing the surface and repainting.

Gelcoat can still show staining

When it comes to gel coats, “water can permeate, but it’s a lot more stable. [Standing water] is not as big a problem [on gel coats as on urethane], but it is very unsightly,” says J.P.

He also describes the cleaning cycle that staining can trigger: “the staining can get oily and ugly, and boat owners will pour degreaser, acid, and bleach down there to try to clean it up.” That observation is a reason to address recurring water and contamination, rather than treating the visible stain as the whole problem.

Check bilge paint for prolonged water exposure

Ferris’s comments point to a practical starting point: identify the finish in the bilge and follow its manufacturer’s care instructions. Check where water remains, investigate new water entry and inspect the coating for damage.

Arid removes residual fluid from the areas served by its pickups. Reducing standing water addresses one source of prolonged exposure, but it does not repair a failing coating or replace appropriate cleaning and surface preparation. Read how the collection and discharge cycle works.

Bahama Boat Works on Dry Bilges and Attention to Detail

By |2026-10-13T17:00:26+00:00April 21, 2024|Articles, Blog, Boat Builders, Boat Stories, Center Consoles|

Arid supplies Bahama Boat Works. The connection is easy to understand when you listen to Bob Sparks, Derek Rawnsley and Connor Henley: their discussion of a finished boat continues beneath the hatches. The bilge belongs in the same conversation as the visible joinery, electronics and deck hardware.

In our Bahama interview, Sparks and Rawnsley focus on what an owner sees when opening that space. Henley takes the discussion further, explaining why he recommended Arid to customers as part of caring for equipment below deck. Their comments give a useful starting point for buyers who want to understand the systems behind a well-presented boat.

The details a boat owner eventually has to reach

Founded by Scott Henley, Bahama builds offshore center consoles in Fort Pierce, Florida. Its current account of its design approach emphasizes positioning components for inspection, service and replacement. That practical detail matters long after the first walk-through.

When discussing a build, ask to see the equipment spaces as well as the finished cockpit. Where can water remain? Can the low areas be inspected without dismantling unrelated equipment? How will someone reach the drying system and its pickups for routine care? These questions make the below-deck specification concrete.

What Arid contributes

Arid collects residual water through pickups connected to a central unit. It serves the low areas included in that installation, alongside the boat’s conventional bilge pumps. Our explanation of how Arid works follows that route.

The distinction helps keep the equipment discussion useful. Removing standing water is one task; cleaning accumulated residue, maintaining connections and repairing a leak are others. A tidy-looking bilge still needs those checks. Ask the builder to explain the proposed coverage and access arrangements for your particular boat.

Fit the equipment to the owner’s boat

In the interview, Henley describes working with owners on equipment choices. That is a good reason to bring bilge drying into the build conversation early: discuss it alongside the systems sharing those compartments, rather than treating it as an isolated accessory.

For another view of access around installed equipment, read Dalton Teeter’s discussion aboard HCB’s Estrella. The Everglades 395 interview adds a captain’s account of an extended trip. Each describes its own boat and installation; the shared question is how the bilge will be inspected and cared for throughout ownership.

Prefer a quick introduction? Watch the existing Bahama interview Short.

Edited highlights from Bahama Boat Works

The following summary brings together the main points from the video. Watch the complete conversation above for the speakers’ own words.

Fit and finish continues below deck

Sparks and Rawnsley describe the bilge as part of the finished boat an owner sees. Opening a hatch should reveal a space that reflects the care taken elsewhere aboard. Their comments connect Arid’s residual-water collection with that expectation of a neat, clean compartment.

The equipment sharing the space matters, too. They discuss the electronics and other components installed below deck, and why the condition of the surrounding bilge deserves attention.

How Bahama Boat Works handles owner choices

Henley places that discussion in the context of Bahama’s approach to building boats. He describes a family-owned business with limited production and an emphasis on fit and finish. He also talks about the practical knowledge involved in working inside a boat’s equipment compartments.

In the discussion of component choices, he explains that Bahama has preferences while also working with customers on their requirements. Electronics and other onboard systems are part of that conversation. The point is to consider how the finished boat will be used and cared for, alongside the equipment specified during the build.

Consider the space around the equipment

Henley recommends Arid in the context of moisture that can collect in enclosed bilge areas. His examples include the combination of water, heat and closed hatches in a marine environment. The concern is the condition an owner finds when that space is opened again.

That makes bilge care part of the equipment discussion. Residual-water collection, access for inspection and continued maintenance all belong in the plan. The interview describes Bahama’s perspective and experience; the appropriate installation still depends on the individual boat.

Bilge System Installation: The Preparation Guide

By |2026-10-13T14:39:16+00:00March 13, 2024|Blog|

Plan your bilge system installation

A useful bilge system installation starts with a clear picture of the boat: where residual water collects, where a central unit could fit, and how an installer can reach those areas. Gather that information before selecting a system or ordering parts.

A dry-bilge system handles residual fluid. Keep the boat’s conventional bilge pumps in place for their intended role. If an existing pump is underperforming, investigate and repair it; adding a drying system does not fix that problem.

1. Map the separate wet areas

Start with the boat in its normal floating position. A vessel ashore, unusually loaded or missing an engine may hold water differently. Inspect the accessible low points and photograph each location where residual water remains.

Include compartments without conventional bilge pumps. Record whether nearby areas connect through drainage paths or appear to hold separate pockets of water. Do not assume every compartment drains to the same place. These observations help establish the number of wet zones the proposed installation needs to serve.

2. Identify an accessible mounting location

Look for space where the central unit can be installed upright, protected from flooding and reached for routine service. Record the available height, width and depth, including the room needed around the equipment.

The engine room or an accessible aft compartment may be a candidate, depending on the boat. Photograph possible locations and the route from each wet area. Leave the final mounting choice to a review of the current instructions for the selected system.

3. Plan discharge, power and tubing routes

Identify potential routes before making connections. Note existing discharge arrangements, available electrical supplies and obstructions between the proposed unit and each pickup location.

Electrical and discharge requirements depend on the equipment and vessel. Have the proposed connections checked against the current installation manual and applicable requirements. Avoid assuming an existing drain, through-hull or bilge-pump circuit is suitable simply because it is nearby.

4. Match pickups to the low points

A flat-bottomed compartment, a narrow corner and a V-shaped low point may call for different pickup choices. Clear photographs and measurements help an installer choose a pickup that fits and can be reached for inspection and cleaning.

Our bilge pickup guide explains the available shapes. Confirm compatibility with the proposed system and its current documentation before ordering.

Watch a six-zone Series 4 installation example to see how the wet zones, central unit and tubing routes come together on one boat. Follow the current manual for the system being installed.

Bring the plan to an Arid dealer

Take your wet-zone list, photographs, mounting measurements and access notes to an Arid dealer. For the system’s current instructions, use Owners’ Central. Good preparation gives the installation review a concrete starting point and helps keep the equipment accessible for future care.

A Guide To Boat Bilge Pumps

By |2026-10-13T20:16:50+00:00March 6, 2024|Blog|

What are boat bilge pumps?

Boat bilge pumps remove water that collects in a vessel’s lower spaces. If a bilge pump leaves water behind, the puddle may sit below its intake or automatic shutoff level, drain back from a hose, or collect in a separate compartment. This guide compares common pump types and explains where a supplemental dry-bilge system can help.

Arid complements conventional bilge pumping; it does not replace it. Keep the boat’s specified pumps, alarms and other safety equipment operational. Neither a dry-bilge system nor an ordinary bilge pump should be assumed capable of controlling flooding from hull damage. Follow the boatbuilder’s and equipment manufacturers’ instructions, and investigate unexpected water ingress promptly.

How do common bilge pumps work?

Compare the job before choosing the equipment

  • Conventional bilge pump: removes collected water according to the installed pump’s capacity and controls.
  • Remote-intake pump: draws water through an intake positioned away from the pump; capabilities depend on the model.
  • Supplemental dry-bilge system: removes residual water from designated pickup locations while the boat’s conventional bilge pumps remain in service.

For cleanup and contamination checks, read our guide to treating bilge water.

Centrifugal pumps

A rotating impeller moves water into the discharge hose. Many compact electric bilge pumps use this design. Pump placement, intake geometry and the automatic control’s stop point affect how much water remains. Water in a discharge hose can also drain back after the pump stops, depending on the installation.

Flexible-impeller pumps

Flexible blades change shape as the impeller rotates inside its housing, moving fluid from the inlet toward the outlet. Material compatibility and permitted dry-running time depend on the particular pump. Do not assume a pump tolerates oil, fuel, cleaners or running without water unless its instructions explicitly say so.

Diaphragm pumps

A moving diaphragm and valves draw water through an intake and discharge it. Some designs allow a remote intake at a low point. Self-priming capability, debris handling, dry-running limits and output vary by model; check the specifications and keep any required strainers accessible for cleaning.

Why does a bilge pump leave water behind?

A shallow puddle may sit below the pump intake or the automatic switch’s shutoff level. Separate compartments may hold water that cannot reach the pump. Hose drain-back and the boat’s trim can also affect the remaining water.

There is no single residual depth that applies to every bilge pump. Some low-profile pumps and remote pickups remove substantially shallower water than others. Compare the actual model’s specifications and your boat’s installation rather than assuming all pumps leave an inch or more behind.

Should you add a check valve?

Do not add one as a universal fix. A valve changes resistance and can affect priming or trap debris. Some manufacturers permit specific valves in particular configurations; others restrict their use. Follow the exact pump instructions. A check valve is not a substitute for a correctly designed anti-siphon arrangement.

Choosing a dry-bilge system for your boat

Start with a map of the boat’s wet zones. Compare the pickup locations a system can serve, its control method, permitted tubing routes, power requirements and access for service. Check the exact model’s instructions rather than assuming one specification applies to every installation.

Plan the installation around the wet areas

If your plan calls for two or three independently controlled wet zones, review the Series 2 configuration and installation guidance. For a different layout, compare the full Arid system range. Confirm the pickup and tubing requirements before choosing a model.

Choose the appropriate Arid Series and configuration using Arid’s model manuals, then bring your wet-zone map to an installer. Our installation preparation guide explains what to gather. Keep the boat’s specified bilge pumps and alarms operational.

How a dry-bilge system addresses residual water

Arid’s automatic dry-bilge system uses small pickups at connected low points and tubing leading to a central unit. Vacuum draws fluid into a collection chamber; air pressure then moves that fluid through the discharge line. The compressor moves air, while the chamber handles the collected fluid.

The number of zones, tubing limits and installation requirements vary by Arid model. Use the appropriate owner manual and installation resources when planning a system. Automatic operation does not eliminate inspection or maintenance.

Removing residual water reduces one source of below-deck moisture and can make new water easier to notice. It does not repair a leak, clean contaminated surfaces or solve every source of boat odor, mildew or corrosion. Our guide to standing bilge water, odor and moisture explains what else to inspect.

Fluid removal alone does not separate oil or make contaminated discharge clean. Review the appropriate Arid add-on devices and their maintenance requirements, or arrange suitable collection and treatment.

What to check before choosing or changing a system

  • Identify where water enters and which compartments collect it.
  • Check the pump’s intended use, installed output, controls and maintenance requirements with a qualified marine technician.
  • Keep conventional pumps and alarms operational. Address leaks instead of using automatic drying to conceal them.
  • Choose residual-water pickup locations and an Arid model suited to the boat.

Explore Arid dry-bilge systems or find a dealer to discuss the boat’s wet zones and installation.

The Do’s and Don’ts of Treating Bilge Water

By |2026-10-13T20:16:11+00:00February 28, 2024|Blog|

What is bilge water?

Bilge water is water that collects in the low interior spaces of a boat. It can carry dirt, oil or other residue, so finding its source and checking for contamination come before choosing how to remove it.

Treating bilge water starts with two questions: where is it coming from, and what is mixed into it? Removing standing water helps, but a recurring leak or oily residue needs attention at its source.

Water remaining around a bilge pump is a reason to inspect the compartment and investigate its source. Appearance alone does not identify contaminants.

Do find out why the water keeps returning

Check accessible compartments after rain, washdowns and normal boat use. Note where water collects and whether it returns under the same conditions. A photograph and a short note can give your service technician a useful starting point.

A dry surface makes a fresh trail easier to spot. It does not tell you, by itself, whether the source is rainwater, condensate or a plumbing problem. Investigate changes instead of assuming they are normal for the boat.

Why should bilges be kept clean and free of trash?

Loose debris can obstruct a bilge pump intake or strainer and restrict water removal. Keep accessible bilge spaces clear so pumps and service points can be inspected. Cleaning and drying are separate tasks: an automatic dry-bilge system does not remove trash or replace pump maintenance.

BoatUS explains why even new boats can contain pump-clogging construction debris.

Do clean the bilge and keep equipment accessible

Remove loose debris and clean accessible surfaces using products suitable for the boat’s materials and equipment. Follow the product instructions and arrange appropriate disposal of the collected liquid. Keep strainers, switches, pickups and service points accessible for inspection.

Routine cleaning and residual-water removal do different jobs. Cleaning removes accumulated residue; a dry-bilge system helps remove the small pools that return between visits. Neither repairs a leak or replaces scheduled maintenance.

Don’t use detergent to hide oil

If water contains oil or fuel, treat it as contaminated water. Do not add soap to disperse a sheen or pump the mixture overboard. Ask your marina about collection and disposal, and have the leak investigated. The BoatUS Foundation’s bilge-cleaning guidance explains why some cleaners merely suspend oil in the water.

Separation equipment also needs correct installation, compatible media and regular service. Clear-looking discharge alone does not establish that water is suitable for release. Follow the equipment instructions and the requirements that apply where the boat operates.

Don’t replace your conventional bilge pumps with a drying system

Conventional bilge pumps handle water removal at a different scale. Keep the boat’s pumping, switching and alarm arrangements in working order. Arid addresses residual water in designated pickup locations; it is not an emergency flooding pump.

Choose the drying arrangement around the boat’s actual wet zones and access. Water in an isolated compartment will not reach a pickup elsewhere simply because both are below the cabin sole.

This public installation video shows how an Arid system fits into a boat. Use it to understand the layout and the questions to discuss with your installer. Refer to the current manual for your model before making installation decisions.

Make the next inspection easier

A useful routine is straightforward: clean accessible areas, address contamination, investigate returning water, and maintain the equipment that removes it. For the drying side of that routine, see how Arid works and the resources in Owners Central.

How Does the Arid Bilge System Work?

By |2026-10-13T14:33:50+00:00February 14, 2024|Blog|

A dry bilge system removes the small pools of water that can remain after a conventional bilge pump stops. Arid uses pickups at selected low points and a central vacuum unit to collect that residual water automatically.

Dry-bilge system vs. bilge pump: what is the difference?

A conventional bilge pump performs the water-removal duties specified for the boat. Arid collects residual liquid at connected low points, including shallow pools below a pump’s effective pickup level or in separate compartments. It complements conventional bilge pumps; it is not an emergency flooding pump.

Why water can remain after pumping

A pump’s intake, switching arrangement and installation influence how much water remains. Some water may also return from the discharge line when pumping stops. A second low point elsewhere in the boat may have no route to that pump at all.

That is why a drying plan starts with the compartments, rather than the boat’s length alone. Open the accessible spaces, find the wet areas and work out which ones need their own pickup.

How the dry bilge system moves water

Each pickup connects to the central unit through an intake tube. The system uses vacuum to draw residual fluid into a collection chamber, then moves the collected liquid through its discharge arrangement. The central unit serves the connected pickup locations according to the model’s operating cycle.

Think of the route in three stages: collection at the low point, transport to the central unit, and discharge. Correct placement and a clear fluid path matter at each stage. The current model manual explains the installation and service requirements.

The animated overview follows water from low points around a boat back to the central unit. It is a useful way to picture the arrangement before discussing pickup locations with an installer.

What a drier bilge helps you see

Removing standing water reduces one source of persistent moisture below deck. It can also make a new wet trail easier to distinguish from an old puddle. That gives you a clearer starting point when investigating a leak.

Drying does not repair the source of incoming water, clean accumulated residue or separate oil from contaminated liquid. Continue routine cleaning, inspection and equipment maintenance, and address oil or fuel contamination separately.

Plan around your boat

Map the wet zones and note access, mounting space and routing constraints. Then use Owners Central for the appropriate manual, or review our guide to boat bilge pumps for pump types and residual-water options.
