Mine went to the ocean bottom in 60'. I have ordered a new one from Bavaria. It has taken 2+ months, in part because one of those months was August. When I do get it, I plan to:
1. Use the fastener on the bottom
2. Drill a small hole in the back of it and run some Dynema through the hole and tie it around the stern cleat.
3. Add foam to the bottom so it floats, in case the Dynema lets go.
I miss my helmsperson seat all the time.
