So now I have the boat

While I whittle down my belongings and tend to the logistical problems of moving everything from Utah to Ft. Lauderdale, I decided on the flooring. It comes under a lot of name brands like Trex but I am going to use a brand called Latitudes. Now what I need is something for the walls. This being a steel hulled boat, any ideas?

We have a boat

Nice boat. What we have is a 40 ft boat with no interior. But awesome diesel engines and a 30kw genset. Pack up your stuff boys and girls, we are going on a trip:) The boat is in Fort Lauderdale in a nice marina. I am trying to figure out how to make it livable. It will take some money and vision but this is the boat. Pictures are coming up.
