Thread: Rear deck attachment build.

If your wanting something that will last, look at Penski Board. Its a very strong and light weight fiberglass composite. Several boat builders have used this for transoms and stringer systems. Holds screws well also, very much like working with wood. Build what you want then some mat with resin, good for 20 years.
It wouldn’t hurt to place a jack under the seat base. Look at the bass cat and skeeter boats web page to see what I am suggesting.
Composite one used to carry it, or one of their sister companies might be closer to you.
