I was at the boat show in St. Petersburg Florida and they were demonstrating this product.
http://aridbilge.com

I also found this alternative.

Not cheep but the aridbilge was impressive. Itís difficult to keep the bilge dry on a CD-25 without changing the hatches.

I guess Iíll have to stick to the wet vacuum for now.😢

A dry bilge (especially during long term storage) rates right up there
with having dry pants. Ignoring this leads to de-lamination of wood
flooring and paneling with mold production in the former and a nasty
fungal or yeast infection (candida) in the latter. Both are painful and
stinky. One sooner. One later.

The nautical prophylaxis is to remove any and all standing water from
the bilge however required (save upside down storage). Wet-Vac, absorptives,
fans, opening hatches, ports or hull plugs coupled with periodic inspection
may suffice. My experience (with both above conditions) is that high tech or
expensive gadgets are not required.

Aye.

Foggy speaks big wisdom.

I have a severe sensitivity to mold spores, yet we are able to sleep in the small cuddy of our 20 ft Bartender, unaffected, because of aggressive cleaning of the bilge. Ours is a dry sailed boat, stored in a dry boat shed, which also helps a lot.

Thanks Tom, I suspect you asked some questions--such as how much power draw--and how often the unit cycles on and off for the Arid bilge?

It's manual and descriptions are a little vague as to how it works--if there is a sensor--or if the pump just comes on with a timer. Not sure I understand the hocus pocus about the several chambers--except oil water separation?

It apparently the Arid unit requires that the box be installed outside of the bilge--and needs a fair amount of clearance.--not sure where I would mount it--but perhaps under the splash well--which is pretty well filled up with various storage and battery items.

The Dry Bilge system, does use a sensor--and the draw is very low--about 720 milli amps a day ( or 21 amps a month--so there has to be some way of charging the batteries. A little hooky about the one strand wire... that you have to co-mingle with multi strand wires to get a good connection.... That is troubling--and you would have to be certain to use a connector with very good glue and sealing properties. Also the small discharge hose--and micro pump--plus the electronics--I would wonder how those hold up over the long run--$400 is a lot for what is there--I suspect that is a huge development cost mark up. But that is what our capitalist system is about. Developing the sensor and electronics take some time and experiments. It sounds like something I would be interested in--if it were half the price. Unfortunately in Florida---we have the mold, spores etc without standing bilge water--it is the nature of the humid environment.

I think changing the gaskets and/or the hatch would be the first thing to do. My 25 leaked a lot through those hatches in the aft part of the cockpit.

Even with extra gaskets--and I have what appears to be close to an air tight seal--some water still gets in--

I looked up the pump he uses--$29.95! Hook one of those up to a hose barb fitting tapped into a block of Starboard, with groves cut in the bottom to where the fitting is tapped in; run the 3/8" line to the pump and out its own thru hull. Put on a manual or even a timed switch --once every XX hours--and for less than $50 bucks you have a manual system--not quite as sophisticated--but perhaps more reliable--if you turn it on--or have a battery charger to run the pump a few seconds every 24 hours...or something like that.

What about a full canvas cockpit enclosure?? Not very cost effective but a dry cockpit and bilge will be in your future!

Jason
I have a cantilever cockpit cover with a full camper back but only use it occasionally. Itís not easy to fish with it all closed up.🐟🐟🐟

Then thereís fish cleaning, cooler dripping, showers and other wet activities. When I have more than 4 people in the cockpit water can come up the drains. Things get wet back there.......It takes a bunch of water to set off the bilge pump.

Drier is better......😇 Tom

If you want custom hatches built that will stop the leaking through the cockpit floor contact

They built custom cockpit hatches for our CD 25 because I hated the constant water in the bilge in a boat with no holes in the bottom. $600 a piece.
We have since moved on to our Lindell 36, but really enjoyed our time with our C Dory

Do you have any photos of your custom hatches? Are they the same size and shape as the plastic ones?

Afterthought:

I've been around boats a long time and, except when on the hard, I've never
seen one completely dry - and that's on the inside, wherever, not applying
to the outside.

So, 'tho it can be worrisome to some, it's just simply not realistic to expect a
dry boat. Concern shouldn't come from water. It should come from finding
the source of the water.

Aye.

Tom,
Thanks for that DIY dry bilge link, I have ordered the parts and will install when the weather gets nasty (BRRR 68 degree high predicted on Tues, but 81 and sunny tomorrow, so it's another beach day for us).
Cheers!
