Hello, I have a bow cushion for the Boston whaler sport and super sport from 1958-1999. This cushion is 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 snap flap is 1” and requires you to install studs in the boat which are included. I make these in white, blue striped and red striped along with sewn pleats for the classy look. 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.
