I pulled up to a beach where a long board contest was going on a couple of years ago here in NZ. There was an enthusiastic young shaper there with some boards with a very similar fin set up to this. I think the fins might have been set a bit wider if I remember correctly. He was raving about them and there were some guys competing on them. At the time I just thought huh. Might have to have a go at it on my next long board.
Bill's got a solid thing going here..........the average person would think that the two fins only equate drag. But what's really going on is increased lift and proximity of the fins accelerates the flow of water through that area.
Bob Krause and I did a whole multi fin deal that played on the priniciple of the vent (Greeks did vents). In one week we went from 1 thru 10......The similarity was that everyone thought "what a bunch of drag".....all those fins.........but the water accelerated through the fins and the increased area created so much lift on our shortboards that we inverted the vee in the tail.......scooped them up to the deckline to help stabilize the boards. They swooped like a seagull riding the apparent wind in front of a wave......and rode similar to a keel. The fence of fins had so much lift!
The double fin is different in many respects, but as I said, the design has definite merits.........kudos to Bill for playing with it.
...hello DS, may you explain a bit more how this set up can produce lift?
you say for the proximity that can produce kind of Venturi effect...
regarding this set up I just have been thinking in all type of things except in generating lift (to really have sense of that in the water in a notorius way)
I blame the guy with the hermaphrodite comment for derailing this thread.
Bill, I think I found another board to route...if there's no takers at the workshop, I'll bring it.
..is this double fin thing perpertrated by the fin companies to boost soft sales???? Oh and my stupid earlier non spell check post meant birds of a feather FLOCK.......duh
Are you sure that bird comment wasn't a Freudian slip?? It did seem to fit. Selling two fins per board is less than 3, 4, or 5 fins per board. So, no, there is not a fin sales conspiricy.
I've never been asked that question, and have not ever considered the circumstance. I just don't know the answer. It could go either way. I think the answer will come, when someone actually outfits a board that they have good nose riding experience with. Nothing like good emperical data. I hate it when I don't know the answer!
I'm loving these testimonials. It's fun sitting here and imagining the board banked over and the twinned tips holding in and all.
Hmm.

Birds of a feather fock together?
Just for the record, I don't have anything against gays.........the real flamers get to me a bit, but I loved "Priscilla Queen of the Desert".

Bill,
I am interested in the set up and was wondering, does the dual setup decrease or increase a longboards nose riding performance?
Thanks
Tony
