(machine translated in 2023) Summer day
Finally nice wind for my GT85. Nice day to test different fins.
The Daytona 8.3 rigged.

First my just made White Water 65cm put under it.
Didn't feel right, no lift, easy spinouts. Also had little pressure in my sail, so also little wind.

2nd was the Deboichet R10 S 60cm. It belonged to Hans' favorite vin.
This one also had trouble walking height, easy spinouts.

3rd was my trusty Drake R13 60cm
Wind was already slightly better, but this fin felt much better, lift was better, no spinouts. Speed wasn't there yet
great, from Hans I got the tip to put the base back a lot further. As a result, the board ran a lot looser and faster.
So now test the other fins again.

Back the R10 S 60cm underneath. Didn't really feel any difference to the Drake R13 in all races. I did find the R10 more creaky in the box. the R10 is also just a normal tuttlebox.

Finally, the White Water 65cm tested again. Now with the wind, the fin worked a lot better. More rest than the R13, but is it necessary?

As with all, that Drake R13 doesn't seem that bad at all.

  (machine translated in 2023) Hans's favorite fin under my GT85. Could plan well, but height running was bad and speed didn't hold up either. I didn't feel like I had enough power in the fin. Next vin.

  (machine translated in 2023) Yes, clearly felt better than the the R10. Although the wind may have been a bit too bad, speed was not yet great. Hans gave a tip to put the base back. Much better. Board ran looser and was faster. Test the other fins again.

  (machine translated in 2023) With the base in the back of the rail and a little more wind, this went very well. speed also good. But the difference between this fin and the R13 is not worth keeping this fin, it is normal tuttle and my R13 is deep tuttle.

  (machine translated in 2023) Now doable, still a spinout, but runs super quietly, I have to test this more often.
