I am doing that now as I got my boat wet. But no not underneath. You would need to cut up your dehumidifer and make it fit better underneath. If you had refrigeration skills, and knew how to solder / braze, then it would be easy. Just find one in the trash, cut it apart and mount each component where you want.
If you've got waterlogged floatation foam then don't waste your time trying to dehumidify it. Won't work.
Only one way to fix the problem and that is to physically tear out the wet foam. Almost certainly you will need to replace stringers as well because they will also be wet and rotten.
I've got an 1986 proline in great shape but a boat dealer said it probably was 500lbs heavier due to whatever wood they used in the hull and floor having absorbed so much moisture over the years
no I haven't weighed it, and it planes easily but just saw some wet wood when I passed the transducer under the floor seems the plywood that the floor is made of is wet. I totally sealed the floor and deck from the top nothing can get under anymore, just seems if you would dehumidify underneath you could really get everything bone dry
Is there any kind of a moisture meter that could be used? I know they make such meters for lumber. I was wondering because I suspect my boat may have picked up a few pounds. It sure feels several hundred pounds heavier cranking it up on the trailer lately.
I don't know what my rig weighed before so I'm not sure what good weighing it would do. I guess I could guestamate based on the owners manual dry weight of 2350 lbs. The motor probably being 350 lbs and the trailer 500 lbs but that would only be a guess.
You can use an ohm meter. Most moisture meters are nothing more than an ohm meter, although they have the algorithms built in to covert the continuity to a %. Get a good known dry piece of plywood and test the continuity. Compare tha reading to the reading on the boat. Keep the probes about a foot apart and away from anyhting that will conduct electricity.
