We tried several different designs for different heights, etc. We also created a prototype seat with scrap wood and hinges, But, what we finally figured out was that our bulkhead is not high enough for the seats to work like the Glastron.
We also figured out that to make this work we would have to attach a pivot point to the floor 3 to 4 inches in front of the bulk head. So if we're going to use up space in the boat, why not just put the seats there instead.
