New backband outfitting for the Seawind

I had been suspending the backband in my Seawind between the two rear seat mounts. However, I was concerned that this would in the long term stress the boat. So today I made some modifications of the seatback. I used a piece of shock cord to suspend the seat across the back pillars, and used webbing to move the stresses of pushing back on the seatback to the front pillars, where the stresses are more inline with the strong longitudinal axis of the seat pillar.
