Am I the only one who thinks this thing looks pretty difficult to surf?

It looked fine to me. I’ve never really ridden proper twin fins apart from keel fishes though

:ROFLMAO: same ol crap

no need for 100k. we offered to help you get a board to salsa but nope

still didn't answer this question:

If this is so important, why don't the top pros have custom ins made for each of their boards? They're not all sponsored by fin companies so it's not that.

I dont make Free Boards - even for bordporn :)

This is Fresno's - you can ask him how it went





You have seen 100's of videos where Pro's are surprised by how a fin change works or an unridden board works

Not much research by Pros in what will make things best .

Yet you need to ask this when you know the answer .

Keep up the good work ;-)

It’s all cyclic fashion
Pretty much. I think my second new board was a twin fin in 1977. 5’6 Local Motion shaped by a visiting So. African shaper. It had a red Buzzy Kerbox chevron type band the huge logo lay on.

Got a 5’10 twin in early 2000’s from Wade with glass-on fins that sat in the glass shop forever because no one wanted to glass on fins.

In 2007 Wade made me a pretty big MR type board that I rode to get in surfing shape after getting pretty fat. 6’3 x 20 x 2 13/16. Worked best as a super twin with the MR retros and a small trailer.

In 2015 Kerry made me a 5’8 quad with no center box that I would put in those huge Harvey Ingleby fins and occasionally ride as a twin.

2020 been having a lot of fun riding the twin Kerry just made me.

Twin fins are fun. But according to Aruka I’m riding them wrong cause I try to surf them like my thrusters. Haha. All I want my boards to do is ride the barrel, surf vertical, go fast, get on rail.

There’s a bunch of guys that ride CI boards or CI clones that surf Bowls. I’ll probably see a Fishbeard or two through summer.

High performane twin fin with a shortboard outline!



Some of the design principles he uses include:
  • A parallel (straighter) foiled outline with forward widepoint
  • Fluid amplification curves, outlines and rocker.
  • Hydrofoil / Aerofoil curves } provides significant drag reduction and higher levels of Dynamic surface planing lift.
  • Balance of volume in relation to surface planing lift. {L = CL P2 SV2}
*SIMMONS FORMULA: Efficient planing surface provide effective lift to counteract the riders weight. Therefore a reduction of physical length, area and volume is necessary.
He goes on to say about his designs:
Naturally, the lower drag and higher degrees of dynamic surface planing lift result in increased speed. Both acceleration and top-end. With an increase of the potential speed of a surfboard design requires equal degrees of control. The balance of these two aspects is crucial to a successful surfboard design.
This guy is a freaking scientist and goes on to reveal more of his formula here:
  • Lengthening of the hard edge (further lift and drag reduction) combined with modern, low volume, medium/ boxy rail profile for sensitive and forgiving rail transitions.
  • A parallel fin placement ( 0 degrees tow) will provide excellent control with negligible drag.
  • Complex Channel and Concave bottom contours and calculated angular and vector tail profiles have also achieved positive results with low drag control through radical directional changes.
  • Custom Designed Power-Drive Fins and Keels (Thomson designed): flex engineered hatchet fins provide increase drive and acceleration through turns with the low drag properties of smaller overall surface area and ability of the fin tips to instantaneously adjust (flex and load) to changing laminar pressures engaged by the rider and environment of the wave, providing constant forward thrust.
Ok, here is the visual of this mini artist extraordinaire:

A lot of people love your boards. I love the outline, foils and especially fins. There's no doubt with that. I just find it odd that you post that "things could be so much better" on other shapers/boards threads.

Most pros on the CT ride the same fins regardless of their board and the Fannings/AM2's were not made specifically for their boards.

When I ordered my twin fin one of the first things Kerry asked me was what fins do you want to use. I asked what do you suggest. He said if you want a performance twin to use the FCS Power Twins. He designed the board, fin placement, sweet spot around that fin selection. He told me to try the MRs if I didn’t like the Power Twin. When I picked up the board he showed me where he thinks I should place my back foot.

I read an interview with Simon Anderson. He said when he is working on a new design he uses the same set of fins when test riding his shapes. That way he can be sure it’s the design changes he makes and not different fins that he’s feeling.

So I always ask Wade what fins he uses when he works on new designs. In fact he got me to change from FCS Fusion plugs to the FCS2 because he wanted me to surf the Large Carvers. Which were the fins he uses when he rides his new designs. I use that as the base fin and adjust from there. But the Large and medium AMs are still my go to fins for thrusters.

Yes my boards don’t come with custom made fins. My shapers are too busy to do that. But because I’m able to talk to them on each order I know what fins were used when the board was designed.

To keep it relating to the original post. The Fishbeard looks fun. I haven’t surfed a keel fin in a long time and have never owned one but the vid makes it look fun.

This your view of these posts and not my message


" I just find it odd that you post that "things could be so much better" on other shapers/boards threads."

This New Fishbeard is in the same catagory as my Modern Fish Keel that I have made for several years .

Its harmless to show this . Barry has done the same .

Nothing negative was said other than from my family of trolls .
