I was never that interested in asymmetrical boards, but recently while on a visual surf trip on the web I became aware of the Bi fin. I did some looking around in the resources and there was not a whole lot there.
My first main question is all the bi fins I’ve seen are built off center from the stringer. Most of them have V in the tail and it makes more since to me to build the toe side single fin side on the stringer. Am I missing something here?
So, if you are so inclined all you guys who lived thru the bi fin and rode/experimented I would love to here your story’s of trial and error…
I love pictures here are a few I have been breaking down the past few day’s
The reason it is off centered like that is because we pivot off our ankles when we apply pressure to start a turn. When you look at the position of your ankle in relation to the stringer, its off to the side about an inch and a half, atleast in my case. Donald Brink is doing alot with this design concept recently, there are some great videos of him online explaining it in depth. It makes for a very responsive board that turns heel-side with very little effort. I made a few of these with a quad on the heel-side and twin on the toe-side, But my next one will be an asymetric for larger waves and I’m going to use an offset single fin with quad option.
Watched a bunch of Donald Brink stuff. Really out there stuff, very function based… very cool. But most of the stuff he is doing is thruster or quad or the Carl Ekstrom twin on your toes quad on your heels school of thought.
I might should have put a bit of my surfing history in the mix and why the Bi fin hit me as such a dynamic concept. I ride everything but my favorite boards are single fins for my logs, hallow waves, and large waves and twins the rest of the time.
When I drew up my first asymmetric outline the other day it really made my head hurt. But after rolling the ideas around in my head for about a week the pain has subsided and I mentally redesigning my favorite shapes in an asymmetrical way.
And yes Ambrose, all respect where respect is due Peter Drouyn is the man. If you watch the clip of P.T. he even states that fact right off the bat.
Thanks for all the leads thus far, I really want to shake out the wood work here before I cut this monster out and shape it down out of just a few pictures a short clip and strait up guess work.
