I have been thinking about Seadek to use for some boats.

You can get it in any thickness to help cushion a bit in rough water conditions as well.

IMO carpet in boats is becoming a thing of the past. hell they are even rhino lining the center console boat floors and gunnels or using Seadeck nowadays for a complete finished look .

I would think you could get Seadek to just lay down keeping it removable in cuddy apps. You can also get any patterns made. All the wakeboard boats are using it currently for the floors and swim decks. it really looks sharp, clean and is extremely light weight plus you can incorporate your own design..

Some other ideas check out the picks. I like that it can be used as padding and again it is super light weight.
