Guys so for 2023 my best fins are: iSonic 77 on 9,4-42cm on 8,4-39cm, iSonic 73 on 7,8-34cm, iSonic 67 on 7,8-33cm on 7,0-32cm on 6,2-30cm, iSonic 63 on 6,2-29cm in strong wind 27cm

Wojtek, jaki zakres wiatrowy przewidujesz dla zestawu 73;7,8 i 34cm? tzn. od jakiego dolnego zakresu to działa ( KNT)

[@thedude6258]

Enjoyed your video ,I'm also trying fins on my 77 ,fins are so important ,

[@douwemonsma5874]

You know Wojtek what you could try is to make a fin that a makes a smooth fillet (curved transition) around the circumference of the fin and the board. Water doesn't like to go around a sharp corner (the angle between board and fin is 90 degrees sharp). If you make a fillet there with a radius of say 3 cm, then you may get improved behavior. Shark fin has a similar smooth transition between dorsal fin and body.

So Wojek, what size of fin worked best? And did they all have the same profile but just different lengths?

[@wojtekbrzozowski]

Yes this were all the same fins just different length. For iSonic 73 2023 the best was 34cm.

[@lchiner]

sound great but why show us and provide us such information if we will never be able to try it, sounds like if you tell us that you compose such maravelous song but you never allow us to listen it, anyway congratulations for you work.. I guess

[@tyniewicki]

Najlepsze finy na jakich kiedykolwiek pływałem... deska idzie całkowicie inaczej ja to nazywam "smooth" a im bardziej naciskasz na fina tym płyniesz szybciej i szybciej, zestaw cały czas przyspiesza bez zbędnych nerwowych zachowań.

[@qbacody]

widać pasję , mam pytanie , stratowałeś już na swojej kosie na zawodach ? jeśli tak to jak wypadłą w boju ?

[@sandromatias4699]

So what size fin work best with your 7.8....you forget to tell US😅

[@wojtekbrzozowski]

Hahaha you are right :) 34

[@kgroszek]

Fin super, na jakich warunkach pływałes na tym zestawie?

[@dveziris]

Hello Wojtek i really enjoy your videos and although i'm not a slalomer anymore i would like to make my own wave fins. If you can make a tutorial video on the construction it would be great help. Thank you for the video !

[@wojtekbrzozowski]

Veziris, I also do waves and am also very disappointed at wave fins. So last summer I tested my slalom fins on my wave board and it was great!!! Finally I had speed that I really needed for high jumps, the grip was there for going upwind and I forgot about spin outs :) Try it, it works extremely well. Slalom fin on a wave board!

[@dveziris]

@@wojtekbrzozowski Thank you !! Will try !

[@sandromatias4699]

I know that you use rdm in your 7.8 sail...why you think the brand recomend a sdm for that sail? Or you Change the Batten configuration of yours to compensate the less power and less stable profile that rdm gives?

[@eddiehatch6636]

Great to see your passion. Are you able to share the dimensions or the build process so some of us can have a try to make our own fins. Thanks

[@GaragePlant]

That would be great indeed. I would definitively give it a try!

[@pitachaja124pl]

Wydaje mi się, że na odklejenie dechy bardziej od fina wpływa ustawienie palety no i technika.

[@wojtekbrzozowski]

masz racje ale tych czynników decydujących o wysokiej jeździe jest dużo więcej :) sprzęt w naszym sporcie jest bardzo ważny.

[@davyvangalen12]

nice video !!!!

[@J3hudi]

hard to imagine, that a sailbrand wouldn't do everything to make a faster sail, or even worse, making it slower on purpose

[@robertcain3426]

Have you guys tried multifins - twins or tris? Smaller fin are faster on surfboards.

[@douwemonsma5874]

low aspect ratio multi fins give poor lift, and lift is needed for slalom windsurfing

[@robertcain3426]

@@douwemonsma5874 Yes, perhaps windsurfing is more reliant on the fin in comparison to surfboards which incorporate the rail along with the fins and where a bigger single fin generates too much drag. Thanks for your comment. Cheers

[@robertcain3426]

Also, the realisation that slalom windsurfing is more about efficiency rather than top speed, as with speed sailing, and the same reason that boats benefit from the addition of foils.
