Fixing to the floor is my next job, only picked it up today. I'm using 14 gauge A4 stainless self tappers and Sikaflex 291 to both bond and seal onto the deck. When I remove the seat I'm left with the 3 leg ovals bonded to the deck, there's no sharp edges and at 10mm thick hopefully no stubbed toes either
My idea is that if I start doing more diving again I can use the same pads and A'Frame mounts to install a bottle rack. The boat would never be a club dive boat just for myself and a few friends to dive out of.
