Yep that's the fin it's based on, the original has a very poor foil though and of course no leading edge bumps, plus ours is only a fraction of the weight of solid glass.

Why does it look sweet to you Steve? What positives do you recognize in the design elements of that fin?

well I've been testing the spitfire version and I'm impressed with the weight, foil and flex, as well as the overall design. The fin performs very well.

I already have a McCoy with a gull wing so It would make a perfect blind test against a fin I know already works well.

Also, excited to test that gullwing in other single fin based designs to see how it goes.

Ok . So does the gullwing design in general differ from a more standard type fin ?

Not all McCoy riders prefer the Gull Wing as I'm sure you know, the foil could be part of the reason.

Anyway foil design is well researched and the McCoy original I have in front of me has several known issues, which to be fair are in common with a large percentage of single fins:

1) a flat area through the middle of the chord, this produces bumps or corners in the curve fore and aft of the flat area.

2) an overly large leading edge radius, this causes drag.

3) a rather thin foil, again common to many singles, this reduces ability to turn through tighter arcs and encourages spin out at higher angles of attack.

4) It's just not a well worked out foil, it's a standard sort of result typical of fins ground out by disc sander particularly those which are on a box base since this makes proper foiling more difficult.

Roy, a friend of mine surfs a modern adaptation of MP's famous cutty board. Its around 5'9" x 20" x 2 3/4" with modern bottom and foil. Looks very similar in planshape to the old MP board. Its one of Mark Pridmores MP3's.

What size and foil shape single fin in your range would you recommend him to try in that board? Its designed to be a 2+1, so the tail a tad wider than a pure single fin. If that changes your advice.

Thanks!

It should have way more drive and much better control, as well as less drag and less weight.

Good looking too.
