Hello, I have a set of new bench cushions for the Boston whaler sport and super sport from 1958-1999. These cushions are made from spradling marine vinyl which is one of the best vinyls out. The foam is a high density open cell marine foam and all the snaps are plated brass. The cushions dimensions are 2” x 11” x 52”. The snap flaps are 1” and require you to insert the snaps in the side of the boards. I make these in white, blue striped and red striped along with sewn pleats for the classy look. I have bow cushions as well. Product comes ships disassembled and it takes about 10 minutes to insert the foam and orient it into the right place. Any questions s please ask.
