Hello, I have a 1991 Penn Yan 245 Contender, currently I only have a Capt seat for seating. I have a small cabinet for lures and we use a large cooler on port side for seating inside the hardtop. I would like to put a padded bench with storage underneath and a wide seat facing back, like one of the options on this boat with the table. Penn Yan used Fiberglass for the bases and I would love to find 2 of these! But I believe I need to make bases, what would you make these out of? Wood? Any suggestions will help greatly! Thank you.
