Does anyone one the board have an RIS Seaworthy Dinghy? The floor on my roll-up is not very rigid underway. I think I may be missing some of the floor. There are some wood blocks on the underside of the floor that look like they are supposed to have another piece join them together to make the floor rigid. I am going to try and make something to lock them together. I am actually thinking of making a one piece floor out of some scrap marine wood and fiberglass that I have left over from a project. I am also considering an application of Tuff Coat this winter. Any suggestions appreciated.
