HWR/LWR fins

[pfaffi]

....... interested in FW?

its more difficult now to make a perfect fin. In the past the FW fins were stiff just with horizontal lift. The new extreme wide body FW shapes with flat scoop rocker lines need also vertical lift to run free and smooth. So the fins must flex a lot to create this vertical lift with the correct rake and should not twist by this extreme flex. Thats the job for the all fin development now. Some of the fin producers got this new aspects and some did not understand that task. The risk is to make a super soft fin which may break by this high flex. So a very good layup of reinforcement is asked.

(my newest G1 fin is flexing under full force (184cm, 91kg) up to 35cm to each side!!!
Compare my older underwater video of my F1 fin in M+ stiffness (that fin flexes up to 20cm each side)

Hi nonopr!
Compared to your former board, 162 (161,160)?? do you use the same fin? Different Rake, Stiffness, Flex, Cut down?
THANKS PFAFFI

pfaffi, VMG blades team has been testing fins for HWR, LWR and other new boards for some time now and I heard they came up with some really good fins, which work on pretty much every board out there. I think even Wilhelm Schurman bought one after testing it in Australia. I ordered one for myself, though I am still not sure if I am going to get the HWR board or stick with my old 162.

Talking about fin compatibility - HWR is based on 161 board and fins that worked with that one will work with HWR too. So you can even use R13 fin in it successfully (not like with 162). In other words, the board is not so fin sensitive as 162. Still, to get the best performance, you will want to use modern fins.

My last board was a 162, did not like it but since I paid for it I had to use it. For that board I had also an CR 70 Xtra Soft fin. Not cut. But it was the version 1 of that fin which had a rake of between 8 and 9.5 and it work really well.
In my HWR I am using the Version 2 of this fin which has a different flex and the same size 70cm and Xtra Soft. It is a lot faster than a Deb 13 and Deb 16. Easier to get going and keep the angle upwind. Downwind is very fast.

How are you fins doing? The Photo of the fin looks good. you can send me one for testing if you want.
Thanks

i sailed this weekend my new HWR with Deboichet R13+6 Soft 70cm (Fin from 2008/2009) and a 9.0m² Warp 2009.
It was very good. Other Drivers with old Formula Boards, who drives my combination ,are very
happy about the performance.

They said it will goes faster than the 162er.
But the HWR loves much power in the Sail, then he goes faster and faster.

This is my first Formula Board and i wonder how easy to use.

yesterday I received my new Formulas, HWR & LWR:
exciting weights!!!
HWR: 8,80 kg (catalogue 8,88)
LWR: 8,90 kg (catalogue 9,07)

Now I will start fin testing.
Will be very interesting how a perfect 162 fin will work on HWR!?
