Re: What do you have on your cabin sole?
there are some waterproof laminaites out there, but I don't see how a "floating" floor would really work on a boat. Seems it would just come up and move around. I just put down 1,500 square feet of it (from Lumber liquidators, and not waterproof) and it was not that easy, and I don't think in a house with molding holding it down it will last the 30 years it's warranty says it will.
There are some nice glue down products, some made from Bamboo that look nice. I looked at one boat that had it and it looked really nice. I also saw a boat with oak; I thought it looked nice but kind of out of place on a boat.
No way for me to have carpet, too much moisture gets trapped. Looking at an S2 and first thing I would have to do is tear out the carpet headliner. The foam interlocking tiles might be cool, but I wonder if they absorb moisture where you cut them? There is also cork, it can look nice but is hard to keep clean.
