Re: adding flooring
Sorry I didn't see your post sooner. I added floor boards to my 14' Gregor. If you havn't already done the project, email me at EDIT (put Gregor boat in the subject line) and I can send you some pics. I used vinyl covered marine plywood and aluminum "L" strips attached with sheet metal screws to the factory metal seats. Came out looking factory installed, and they're plenty strong.
