I had a thought. Many of you are also kayakers. Some of you whom kayak have aftermarket seats. There is a popular seat made by surf to summit that is mini-cell foam laminated in some sort of thin nylon fabric. The fabric is thin enough to allow the foam to flex yet tough enough to resist frictional degradation and tear out.
I think something like this could be done for a DIY boat seat. Just a basic rectangular boat seat about 2-3" thick. I could integrate some drainage grooves like the actual kayak seat by simply using a router too. Building this would require a low pressure vacuum table (I think) and some sort of spray adhesive. In the past, for architectural boards I have used 3M 77. For this application I do not think 3M 77 would be desirable for obvious reasons. So, does anyone know of another spray adhesive suitable for outdoor wet conditions? If anyone has any insider info on how Surf to summit does theirs....it would be greatly appreciated. Thanks
Update: Found some more info;

Looks like this guy used contact cement on his seat.
