I had alot of vinyl flooring left over from a remodel that I did. The vinyl is a foam core with a ruff (matt) hard finish on the top and is about 1/8" thick. I left it out in the sun for about two hours to see how hot it would get on my bare feet. It still felt comfortable. The question is: Has anyone used this in their boat? You can go to Home Depot or Loews and see this type of flooring and it is not that expensive. It appears to me that it would help for sound control and dress up the boat.
