Fin professer [jekel] pepe good stuff mate cant wait 2 see it on the water!

That's actually just to get the 2mm of black silicone to sit flush with the board, but I do use it with some wet and dry to make sure it's level.
After the test run today I'm convinced that it's the best weedie I've used, and with a few minor tweaks it will gybe a lot tighter (the fin maybe, not me). I need to move it forward about 1cm, maybe 2?? So I can get the centre of effort in line with the rear footstrap.
Now I wonder where I can get some carbon laminated g10 !?

Very nice Keef, is the carbon laminated over g10?
Took me a while to get the foil right and I couldn't use the traditional eppler or naca foil as they're about 9-10 percent. So my foil was done by eye. And alcoholic ginger beer

whoops, sorry, there it is

After a fair bit of R&D the fin was retrimmed and laminated with carbon, but it seems to resemble Tim Hemer's "Tomahawk", honestly Tim it just turned out that way
30 cm, 434 sq cm and 43 deg. Around 9 percent, I theenk. profile guage? nup!
Carbon laminated over polyester.

Nah , that's just an illusion. He took the photo on the way to the fridge for another one. :-))

They can custom make you G10 panel with layers of carbon inside if you like.

They prepreg fabric themselves in their factory and can laminate to your specs.

They may have stock you can purchase already made.

Cheers Kimba, hoping it will do the 69 with a 7.5m comfortably.

Taking orders, with a free ginger beer thrown in

Not sure what's happening here. Tested out the fin which goes well, until you try and throw it into a gybe. Then things get interesting, board wants to keep going, or spin out in the opposite direction. May have too much area around the tip of the fin. Or the cut-out is not profiled thin enough. More testing needed.
Wondering now whether when the board is transitioning through the gybe the lift is transferred to the other side of the fin, giving it lift and thereby throwing the whole process on it's head. I wonder if the thickness of the fin could do this?

No probs Kimba, think I'm going to go about 9 percent on the second fin.

2 things slowing the fin down at the moment. Leading edge is blunt as a bowling ball and the chord near the tip is (was) about 12 percent. Like driving with the handbrake on. See what happens today
