My 1973 model 25 foot Dolphin (I just bought it a few months ago) has had all the decking wood replaced with 3/4 inch marine plywood about two years ago, but at that time they put non-marine type of floor covering on it (They used Berber carpeting) I am a do-it-yourselfer planning on getting rid of the Berber, and I am finding plenty of choices available as far as marine type carpet.. The really high end stuff is a little too expensive for this old boat (nearly 50 dollars per running foot from some sources) So I am considering using something less costly - (Either) a rubber back indoor-outdoor carpet (Or) a snap together vinyl laminate flooring on my boat, now that the water proof vinyl is plentiful and relatively cheap.. the boat is stored out in the open, uncovered, so I would like to stop the water from reaching the plywood.. I also want a textured surface that is not real "slippery" when wet.. And I know that whatever I do use will deteriorate within a few years from daily exposure to the elements.. I bet a lot of people have used the vinyl laminate snap-together flooring on the boats, please let me know how well did that work out for you ? Any helpful comments or input would be much appreciated, Thanks Everyone..
