Hi I just have buy a Sandpiper 565. I remove the toilet and discover that the foam in the boyancy compatment is very wet. Bad surprise. I ask myself if that foam can dry with the use of a fan or dehumidifier. If it dont do the job, I will have the get out that wet foam and remplace it. Does somebody already solved that problem ?

water in foam
One possible source of water entry is the pump-out hose for the toilet. This hose passes through the anchor locker floor and down to the toilet. A foam sealant supposedly prevents water from the anchor locker from leaking down beside the hose. Since the anchor locker floor slopes downward towards the drain hole in the bow, water should drain away from the hose. However, if the drain hole is plugged, and if water collects around the hose, it could penetrate into the foam floatation. On my own Sandpiper, I cut the foam away from the exposed hose in the anchor locker. I then cut a fiberglass plate (about sx inches across) to fit around the hose, and using good marine sealant under the plate, I screwed the plate down to the anchor locker floor. The sealant squeezed up around the hose and down onto the foam floatation below, thus sealing out any water. This may be a possible solution for your problem. Of course, you will still have the present water in the foam. I think this is a closed-cell foam so it may be a problem of drying out the water that has accumulate around the foam. Perhaps you could fit a small inspection hatch (or two) that would allow you some air circulation and possibly allow you to drain some of the water.

How ?
I dont know who I can circulate air in the compartment, it is ful of foam. I dont know either if the front compartment is connected to the rear one by the space under the interior floor. Shoud I make some visit traps in the rear sections ? The part of the toilet hose in the anchor case is taped with fiberglas. I dont think water can come from there. Thanks for your suggestions

Any small openings in the compartments will allow
water vapor to escape from the foam. If you place a wet sponge in a bottle and put a lid on the bottle the sponge will stay wet for a very long time. But if you don't put the lid on the bottle after some time has passed the sponge will be dry. Water vapor is lighter than air so if you provide some openings the water will dry away. I don't think that the water accumulated in a one time event but likely arrived in small ammounts over a long period of time.

water in
When the boat was not yours, it is diffucult to determine how water came in. There are traces of water drop at many place where are fasteners on the deck. The wood planks on the outside are also unsrew a few places. I will correct the scellant. I can't see the centerboard case, it is a big job to inspect it. I notice I will have to lift the boat and get the centerboard out. However, I will check how hw water gets in.
