Iain.........since nobody has jumped on this one.........I'll try to help you. ..........I have had little experience with what your going through right now......but. See what you can find on you tube. There should be a bunch of video on what you need to know. I know I have found it very helpfull with stuff I am cueless about.
The carpet issue........I would use carpet. Buy the right wood water proof it correctly....cover the boat when not using it and there is no reason not to have nice cushioney carpet in your boat. Google this and I bet you will get all sorts of video on how to answer your problem........
I know I am not answering your questions directly but atleast this should help you get started.
Another great website in which there is alot more traffic than here is
www.baylinerownersclub.org There is a project section and just do a search that could help you too.
Hope this helps
Roger
