Force Fin SD-1 Military Proof of Concept.

Description

We won an International design award sponsored by Stevens Urethane, Massachusetts (acquired by SWM International) for our patented manufacturing process.
Sheet urethane is an exoskeleton in to which our custom cast polyurethane was pumped to fill out the fin structure and form. The Fab Force Line of fins were made without molds, as their outer skin layer of the fin is the mold. Add a recycled tire sole plate.
