As those of you with the bow seat option know that it fits well in the bow, but less so in the side door location. On my S-boat there is about 1.5" of space on each side of the seat when placed in that location. Here's my solution. I went to West Marine and secured two stainless footmans loops, two 1" stainless rings and 4 stainless screws. This cost approx. $20. Now I can stretch a bungee cord across the seat (it hides in the seat's fold) and the seat stays in place. These images show what a footmans loop looks like, a close up of the installed parts and a photo of the opening with the parts installed.
