I just found this on Facebook. It might be too new but has anyone tried or seen them?www.facebook.com/Wave-Wing-SUP-Fin-132959330424959/
It caught my eye after that Kai Lenny foil video I guess.
Found another vid here. There seems to be wee bit of progression in the SUP world lately.
Hmmm...looks like the Starfin by Cheyne Horan,
except with an interesting lockdown mechanism.
I thought it was George Greenough and the tuna fish responsible for the basic surf fin as we know it. Prior to that mostly D fins??
Grandchild of Professor Julius Sumner Miller? Why Is It So?
Why wasn't the wave wing demoed in the surf, hmmmmmm
The explanation video is so full of bovine excrements it is actually quite funny.
Any lift from the winglets will provide drag. The design of the starfin is made for crafts rolling to the side (sailboats, then surfboards) so that a winglet becomes vertical and compensates the tendency of the single fin (or sailboat keel) to "slip" with roll angle.
Note I had a Starfin on my 6'6" SUP nearly 5 years ago... (pic below)
The issue with it is that, depending on the tail rocker, the winglets would induce extreme drag if not properly aligned with the water flow. But with the proper angle, it is quite fun, you get a single fin that keep its bite in turns. Alas the vertical, "spitfire" shape is quite twitchy in turns...
I agree with Colas as I also have an old star fin that I have used on surfboards in the past but now I am testing on wave sups :-)
That is Cheyne Horans Star Fin which he designed with Ben Lexan after we won the Americas cup. What ever benefit you get from it you will loose in drag from that black knuckle behind the fin in drag. Plus he is comparing it to a down wind fin. That was the most ridiculous explanation of Cheynes fin , I just don’t get it . WTF does the rocking fin do to improve performance ? You surf with your back foot over the fin not 12” in front of it , what meth induced computer model did you get that from (6.53 in your video) Sorry I can’t hold back that was a load of rubbish.
Cheyne is a mate of mine and I have forwarded this to him and this is the worst representation of his fin I have ever seen , it’s just a load of bullsh!t.
The Star Fin has merit on a performance Sup and if you want to try one go here and not from kook.com:-
Apologies for the rant but please send me a personal email if you are offended email@example.com
All good points, um but I think your starfin is in back to front
Yup, screw is in the back - most vertical edge is the front
(which is why they call it a Spitfire).
For me, it is hugely responsive like other pivot fins; however,
not too twitchy, more in control, I think because of the winglets.
