Restoration of Old Sandy

Hi all. I'm restoring my first boat that I purchased in 1986. This old thing is a 12 footer. Last night, I tore out the old (and filthy) carpet, and today I replaced the seat. Common sense should have told me not to put the new seat back in until the flooring was inserted. Doh@ This is a really fun experience. I'm not sure I get why they put carpet in a bass boat, I guess I get you can't put tile in one. . . get too hot, plus all the huge bass I catch would shatter the floor. Is there another material I can use for the flooring that isn't carpet? You should have seen the filth under that carpet. I should have done this years ago. Any helpful suggestions on this project would be appreciated.
