A boat yes, but treated no different than my home.
The original carpet is foam backed and glued down. The foam backing carpet is hard to find, other than the cheap
quality Menards type which I won't install.
When I say not a concern, that is because it will not get wet. We boat on a small lake and have a covered slip. If it looks like rain, we don't leave the slip. When done swimming, we dry off before going down below. Boat only gets wet on teh outside when it gets washed. Just a different type of boating
than most on here from what I can see.
Back to my question, a lot of my friends have houseboats that have your normal looking carpet. The marine grade selection, from what I am finding, is very limited and nothing like I see in other cabin
cruisers. Hence why I thought that regular household carpet was used down below, just not sure if it is.
