We replaced the carpet in our new boat last fall. We asked a recommended local carpet company what carpet they recommended for long lasting wear. They used some sort of nylon carpet. I ripped out the old carpet. They said we saved about $1,400 by doing that. It cost $2,900 for the install. They did such a nice job that we hired them to do the tile work on our bathroom remodel and used the same carpet in our bedrooms in the house. Find a company that does a fair number of boats. I called several floor covering stores and asked who they recommended.
