Default water logged foam in a boat.

we had a small water line ( from the wall to the back of the toilet plastic fitting) burst and flood the house. we did the whole dry out process including dehumidifiers. that got me thinking, if you had a boat that with foam that is water logged, any reason you couldn't put a dehumidifier down in the hull and let the machine do its job? it had no issue drying out the house? at first i was skeptical about them and though there is no way its going to make that much difference. we had 4 machines in the house, turned them on about 4pm. there was a brand new loaf of bread on the counter, the next morning the entire loaf looked like you put it in a vacuum seal bag and sucked it down, also dry and hard as a rock! now i know they do work!

so could this take care of a wet foam problem

Sure, it would just take much longer.

It would work if you could get the machine into the hull.....but not the case on most boats. Foam is generally sandwiched between two pieces of fiberglass and no way to get the machine in.

If you had a smal garage that was relatively air tight you could put the boat and dehumidifier in there together. It will take a long time but will work. Did I mention that it will take a long time?

Just tape into place a small tent like structure over the hull opening with the machine inside.

that would have been my original though, however after watching the machines work in the house, if you have the appropriate amount/size dehumidifier for the space, it would actually work pretty quick. in 2 days or less they completely dried out a flooded 2000sqf house bone dry! i think that they actually dried it out way to fast, due to an extreme amount of bucking of the wood floors. if wood is dried out to fast it will twist and buckle ( lumber from lowes ) if its done correctly the wood will only twist or buckle to a minimum

Try a 5 lb container of a dessicant in the bilge? When they fill up you can 'cook' them in the oven and re-use.

Never tried this, but it might work.

check out Dryboat. I saw one hooked up to the system. pretty crazy drilling a bunch of small holes in the boat.

In order for the foam to dry it would need to be exposed so removing one of the fiberglass skins would be necessary. Even then the foam is going to very slowly give up the moisture.
If I remember correctly Tom W Clark [a member on this site] did a series of tests on Whaler foam. It more or less concluded that it was not going to dry out.
