Give a man a fish and he'll eat for a day.
Give a man a 3D printer and he'll try one or two idiotic schemes and then leave it in the shed for ever after.

It seems water goes in the front and out the sides .
why ?
Is there an intergalactic space module inside ? The Japanese can make them pretty small these days .

They're talking about them in SUP forum
Looks dumb, even if it works at surfing speeds I can't see it will at our speeds.

Everything old is new again. I remember having something similar, Reckon it was 1990 or 1991.

White fibre-glass fin, more swept back that the picture and probably more of a bump and jump thing than a slalom fin.

It had a slot on the leading edge that fed a row of holes about half way back on each side. Probably 4 or 5 holes each side, maybe 8 to 10mm diameter each from memory.

I remember it well because I never worked out how they made it. If it was molded it was a very clever mold and if it was drilled afterwards it was a very neat routing / drilling job to get one slot into multiple holes in a pretty small space.

I am sure it was a hi-tech (hy-tec ?) fin, same brand that made the Kalama black tip.

Performance-wise I couldn't tell the difference between it and similar sized solid fins. Seemed an awful lot of effort for nothing, but looked pretty cool.


The Kalama Black Tips on the other hand were the greatest wave fin ever produced.
