Maybe someone in the Swaylocks community might have some info or knowledge on this old Hobie twin-fin. It’s been in my garage for a few years but I pulled it out of the rafters last week to check the fin boxes. I was going to search for some Guidance fins online which seem to be next to impossible to find. Anyway, the dims are 5’7" x 21.5" x 3.5" and the serial number is TM57309. Maybe it was shaped by the late Terry Martin?
I had a Hobie twin fin in 1971 tha I think was shaped by Munoz. Yours seems to be the same era. Does it have a flip on the deck side of the tail?
No flip on the deck side near the tail Surfifty, just a large bevel that reduces the thickness. Tons of V in the last foot on the bottom, I would love to take this board out for a spin if I could find fins for it.
Aloha,…
This twin fin shape was similar to the last team Hobie I had '70----mine was 5’4", shaped by M.M. with his Ogden logo stamp, part of the end of the Positive Force series—PF IV----had the Positive Force laminate.
I cut down the fins on mine.-------G.P.'s twin at the time had the same template but with a fuller nose.
Guidance System fin system, used plugs to shift the fin from one setting to the other.
