Hey Wildcat. I have used them in my basement due to the few gallons of aquarium water running though the house. I doubt they would do a lot of good. They only absorb from the moisture in the air and, you have to pour the water out of the cup from time to time on the ones I used. When our boat sat out with the same seats, we had to use the shop-vac to suck the water out after a storm everytime. It was a real pain in the behind too! I'm not sure of permanent solution for you buddy.

Yep, won't be adding any drains, since the underskinning is on and I don't want to remove it now to just add drains , so now that the boat had a chance to get dry over the last 3 days, wife and I got the cover back on before the heavy rains return today. Now some moisture absorbers might be handy for some minor dampness over the winter months and eventually I'll be adding those Bass Pro vents (shows one, but they are a pair of them) to the seats like I installed in the seat and console compartment where the batteries are located. Oh well, was hoping we'd get out this weekend for our last shot. So it'll set up now until early spring (around March for us).
