A glass IN single fin ....

Would anyone have an idea roughly what year a fin like this would be ? [My guess is somewhere between 1969-72 maybe ? Although , not having the hole for a legrope to go through , perhaps it was later ?]

cheers

… unfortunately the guy I got it off threw the board away , so I couldn’t check for a legrope plug , and also , he wasn’t sure how big the board would have been [pieces were missing , evidently !]

…it’s 8 3/4" deep , with a 6 1/4" base , if that helps …

here it is alongside a thruster back finbox fin …

That’s a tough one. I recall seeing similar fins in 1968-1969 on the East Coast US when the wide-tailed deep V-bottoms made their appearance (e.g, Con Iron Butterfly). However, those were somewhat deeper, all molded poly, I don’t recall any lay-ups or glass-ons. The closest match shown in Stoked-n-Board is a 1968-1970 Greenough Stage 3, but that was at 11-1/4" deep. 9-1/2" base, and in ABS for WAVESET. I don’t recall that leg ropes were yet in use here at that time.

Sorta smells like late 1967, or 1968. Actually reminds me of the fin John Kelly was using on his ‘‘Hydro’’ model boards of that era.

I wonder if it was not reshaped by the owner from something bigger. What makes me say so is the approximative foil. It doesn’t look like a pro job.

Because of the short length of the base of the fin, I’m certain the shape is the original design, and not cut down from a larger fin. Many larger fins WERE cut down, when higher aspect ratio fins began to appear, and proved to be superior to the standard D type fins of the day.

thanks for the replies , guys !

…it sounds like it was a pre-legrope , ‘transition period’ board’s fin then , from what you dated it to be.

[now I’m wishing he had kept the board , too [no matter HOW butchered it may have been]

cheers

yeah my first thought was a re-shape too, bill is right though the base is fairly short so it wasn’t a D-fin but possibly a greenough or similar?

if it IS infact the original shape, you are correct in saying that it’s not a great job!
