" I assume by the floor you are referring to the "deck". First very carefully remove the existing deck, noting how it was fastened and what it was fastened to. Most likely it is marine plywood, glued and screwed to wood stringers, possibly fiberglassed. Obviously before this happens you will have to remove seats or anything else attatched to the deck. Make sure whatever supports the deck is dry and in good condition before trying to rebuild. If the stringers are in bad shape you may have to "sister" them. Try to save deck as you remove it for a pattern for the new deck. I am guessing that this as a fiberglass runabout or similiar boat. If this is so, you will probably find that the plywood deck is covered by a layer or two of fiberglass and resin. It is imperative that this be replaced in the same manner as to maintain a watertight deck. After deck is replaced, you may replace carpet or whatever was covering the deck before. My personal favorite finish is to apply a coat of marine deck paint (after fiberglassing) and adding no skid sand. This makes a great no skid surface, easy to claen. Then for comfort if you wish I add marine or indoor-outdoor carpet pieces that can be easily taken up and cleaned and dried between uses. Good luck, and post your results.

Sorry to be so long winded, but it is can be a fairly involved job, but is usually worth it and a lot cheaper than hiring it done. "
