Caution Speedwings

Postby FredBGG » Sat Sep 19, 2009 6:31 am

I saw in a magazine that Caution will be marketing the Speedwing fins by RFC.

http://www.rainbowfins.com/surf/a_rfc_speedwing.php

I have been using them (RFC lable not Caution) on my Aviso Surfboards. These fins are great.

Seemed like a gimmick, but there were a pair on sale at a surf store so I grabbed
a pair. They are great. They reduce drag and leave a cleaner trail.

If you have a surfboard and kite is low wind give them a go.

Good to see that a mainstream kite company has adopted them... confirms my choice in using them.

Same thin with Slingshot and Aviso surfboards... been using used Aviso's for a while now...
good to see Slingshot adopt them.

Can you post a pic of your fins? The site has that tiny pic so cant see much from it. I am interested in the fins, hence want to see a larger image.

Thanks

Here is an illustration of the principal on how they work at least in the case of an airplane:

It makes sense so I ordered a set of these fins for the fun of it (future box). Will put these on my surfboard and comment on it after a few sessions.

Thanks for the tip....

Cheers!

Very good resutls so far.
Only had two days in the water.

Second day was a good day for testing as the wind went from light to strong.
So far I can say this....

Increased upwind preformance and speed.
I was also happy to find that the board was actually more stable at high speed when I expected to have problems.
On the downside I found it harder to do jibes while carving. No problem jibing by switching my feet around before or after the carve, just durring the carve... especially if going fast.
I sort of found that the board could easily shoot out infront of me if I misplaced my feet.
Straight downwind is very fast too. Felt like the board could zing out infront of me.
I'm guessing this is because of the reduced drag or "lack of resistance".
I actually got used to it quickly.

One other thing I noticed is that I could ride the board furture back sooner. I'm guessing that reducing the toe-in at the top of the fins reduced the downward pull of the fins.

I also tried the fins in the waves and the turning prefomance seems to be just as good as before.
However I did most of the wave testing in the dark with the moonlight so..... well I was just stoked to be riding waves in the moonlight and not being able to see much.

This weekend I hope to test the fins some more.

I also made a pair of "reshaped" speedwings. It will be intresting to see the combined effect of wings and "Progressive Toe-in" (twisted fins).


Hey Twisted fins sounds good.... I think I'll officially call these fins Twisted Fins

To conclude I'm suprized how much difference they make... I guess water is dense and small changes make quite a difference.

Been riding the Caution surfboards for a few years, and just got a new 2010 Caution Trespass that came with these fins. I didn't know what to think at first look. All I can say, is they work. Seems to have more upwind performance, a bit faster, etc... I highly recommend them!

I think Caution made a smart move adopting these fins.
