We've been working with Carl Ekstrom and he's done some crazy asymmetrical boards:
First one is a Simmons type hull but modified to a customer's specs:
[img_assist|nid=1059434|title=Carl Ekstrom with Scott Bass' Quad/Twinzer fish. Scott says it works unreal!|desc=|link=none|align=left|width=0|height=0]
And this one is more performance fish like:
[img_assist|nid=1059435|title=This board is more of a performance fish rather than Simmons style board|desc=|link=none|align=left|width=0|height=0]
This last one is what we've been focusing on in my shop, a shortboard
with more vert performance in mind...
[img_assist|nid=1059436|title=Post-lamination, this Asymmetric shows the two-tailed approach|desc=|link=none|align=left|width=0|height=0]
I think this one was 5'2"/5'4" (been writing down 2 lengths,) but was derived from a
5'10" regular board.
[img_assist|nid=1059437|title=Our finner Pat, puzzling with the offset center fin box for a thruster A_Symm|desc=|link=none|align=left|width=0|height=0]
The empasis of the center fin on the "toe side" rail was to give that side more
drive, but to offset this drive (and the opposite of was Carl was doing then) the
rocker off the tail was flipped (increased) about 3/8"
[img_assist|nid=1059439|title=5'4"/5'2" x 20-1/4" x 2-1/8" Goofy foot version.|desc=|link=none|align=left|width=0|height=0]
Sorry he's goofing off in this shot, but it shows the overall outline. Basically a
round pin on the toe side and a favorite hybrid fish with a wing on the heel. The
last 3 boards have shortened noses to get quicker swing which in turn allows for
less mid/tail rocker which in turn yields more speed. Note also that the heel side
is shorter, BUT has less tail rocker off the tail (and between the feet.)
Now, before jumping to the conlusion that these boards are wild, the feedback
has been that they handle quite well. They also paddle well which is a good sign.
I liked the comment that "if I closed my eyes, the board feels like a normal board,
but turns better and has more speed..."
I want to also note that Carl Ekstrom and Chris Ahrens have been onto this for a
long time and that I'm just a short-timer on the newest ones (I did a few in the late
70's but not this crazy and was not as aware as now.) Carl is great to work with, just a
class-act all the way, I really like his model-making, he was totally liking our computer
modelling so I'm stoked to report that he is up-to-date in that area.
Regarding the Vinny Bryan comment, there were a lot of creativity along those same
lines in our zone here too, and Benny Ferris and Jon Riddle made a lot of their Edge
Boards as asymmetricals, some VERY radical, which worked well but were superceded
by the next week's new thing, ha ha.
So anyways, a lot has been going on lately, I got my newest personal A_Symm done
and hope to test it soon, maybe I'll post some pics if interested, it's 5'6"/5'8" x 19-1/4" x 2-3/8"
With what's been found out so far I know the design push has been going in the right direction.
Thanks,
George
