Hade a look at Sam’s work really love what he’s up to . Alternative yet practical been using his find for 8 years now . I dig how open he is to change and trying things out .
He met Marc a few years ago around the time the paper was published and decided not to pursue the idea. He considers it impractial to do on a CNC machine and suggests moulding would be more appropriate though that would also have some issues.
My own take on it is that reducing fin drag by 13% probably has very little impact on the total drag. I mean if the fins are 10% of the total drag then a 13% reduction translates to a 1.3% reduction of the total drag.
Finally the application of data from testing fin drag under lab conditions to actual surfing is fraught with complications. Unfortunately, for most surfers, the only reliabke methids of increasing speed are to improve their technique and work with a competent shaper to develop more suitable boards.

Thanks for the share, those fins are incredible. I would love to try any of those out.
Ping him a message and have a chat .
I will pass this on to my friend who runs a business using a CNC machine to produce fins and let you know if he is interested in trying them out.
