Locked up in Guantanomo in his orange steamer

In a concrete bunker with a cupboard full of tinned beans and corned beef.

Oh well, I'm going to make my own fins from now on. Roy told me he has stopped producing the printed polycarbonate fins.

well that was an interesting and telling read.

Isn't Roy a millionaire now? He doesn't have time for nickel and dime bullshit from wageslave cubemonkey battlers.

That explains it .... the micro collapse of his business and my $90.
No hard feelings Roy ..hope the sun rises kindly on yours
Take care

That sucks - but truth told - so did the fin. I used it in my mlv and the board turned, but there was no drive. The fin was flimsy. Let's see if those comments bring him back here.

Did you pay by paypal? Because you can get that back usually.

He posts on instagram occasionally...

Pretty sure the fins were only a small part of his business.

i really liked the fins.

The bumpy leading edge has more surface area than a fin with no bumps, therefore more drag.
Think corrugated iron, when it comes off the roll it's much wider.

You'll definately get he back in here talking about drag lol.

there's more to drag than surface area in hydrodynamics.

the fins definitely felt drag "free"

Here we are, 21 months later, and I have developed and produced a fin. I call it the GullWhale fin: The ride reports are extremely encouraging. I have made a few different versions and tried out a wide range of ways to make them. About 7 surfers have surfed these fins and only one has snapped off in the last 6 months or so of testing. I have since then improved the manufacturing process and I think the fins are much stronger now.
I think the fins are mature enough to start sending a few more out for testing by more surfers.

Steve, would you like to try one out?

How big are they? How do they improve on existing templates?

194cm^2 area
Depth 250mm

Main improvements: Very high aspect ratio but 'Curviness' everywhere.
Designed using finFoil https://finfoil.io/ until it looks most pleasing to my eyes (which is a long and slow process).

It results in very high lift to drag ratio and an exceptionally forgiving nature.

Picture shows a yellow GullWhale fin and a red HARFTUB-7 in relation to an 8ft board. The HARFTUB fin is 11mm shorter and has practically the same area (193.45mm^2).

I have experimented with basically 4 outlines and then permutated them through multiple different foils, thicknesses, thickness distributions, and different numbers of tubercles.

For each of the sea-worthy fins in the photo there were multiple precursors that never made it anywhere near the ocean.
