Force Fin Designs

[Bob Evans]

Aren't you a bit gloomy on that one ? I'd have said an archaeology dig...

Maybe a grave yard would fill the bill. Very depressing to be pulling out years of Force Fin designs and not sure what to do with it all. And then other designs like Camera systems I made before Fins...and maybe push it all into a big hole for a archaeology dig?

Found boxes and boxes of fin drawings...but Professor Harry Wirth sums up my designs.

Found several boxes of early Force Fin drawings. I used a plug made from inside my Jet Fin. At that time I thought the foot pocket part was going to be easy. Later I changed the foot pocket design to the Open Toe. .This drawing is working out how to hold the inside plug within the two other mold half's. In front of 28 Anacapa Street La Mer Bleu Productions office. My first Urethane Force Fin 1974. You can see the wood dowels holding it all together.

This rod slipped under the foot pocket.

While working on a Force Fin Mono fin, I had to find a way to move the flexible wing into the right position. Made a fiberglass turtle shell with a way to hold and move the wing. Holding the Turtle shell in my hands I worked myself backwards. At one point I flew across our home pool. Afterwards I made and Patented the Mono Force Fin designed from early testing. Such a small market, I never went further. Have 2

pair to sell.

Falling a sleep with this SB group. Stopped supporting the creep of FB, so it looks like reaching out on media outlets is gone.
