Re: Insulation
I'm using Armaflex on the bulkhead between the engine and the kitchen, similar to neoprene but fire resistant. Very expensive to do my entire boat in this, and I'm perpetually broke, so yoga mats it is!

Re: Insulation
The armaflex is great stuff. The potential I am talking about is moisture condensation behind it. It won't get wet itself but it might trap moisture behind, betewwn the foam and the deck. I think that nearly the only way water in a wet deck can get out is if the interiar glass is a little bit porous. Cover it with a vapor barrier and add condesation. That would concern me. Just sayin'

Re: Insulation
good ventilation is the key if you want to avoid condensation,
on our alloy boat in the cold, cracking the hatches during winter solved most of the condensation problems related to running heating inside.

Re: Insulation
any foam that wont start degrading and coming apart should be pretty good. (Blue or pink construction foam, styrofoam type products etc.) Generally, enclosed air = insulation... which is why foam products work. I wouldnt use rock wool or a spray in product. You really dont need any insulation up there, but it can help in hot weather or cold for sure.

Re: Insulation
Good or bad, this is what I did. I took a short lenght of pipe (cut to the length = to the thickness of insulation you are going to install) and welded a washer on the end of it. Then I removed the nut from the bolt and placed the washed over the bolt. Use a socket to reach up into the pipe and relpaced the nut. Next I sprayed polyiso foam around the pipe. This provides good insulation and I still can get to my nuts.....

Oh! I had to read that a couple of times, but I can see it now, that's a good idea. Another idea I'm trying to figure out is how to not only have easy access to the grab bar nuts but maybe I can put up a grab bar inside the cabin. But its so far away from the original design, I don't know if I should do it. I've seen it done in newer sailboats.
