View Full Version : For Remi/Ian: Fin for is122 2009?

9th February 2009, 03:04 PM

what deboichet fin (model/size/stiffness) would you recommend for is122 08/09 for 8.2m2?
My weight is 83kg and I am looking for the most all round fin for with very wide range and it should be very fast. It will be used in flat water, chop, in downwind slalom, figure of 8 slalom...pretty much every possible racing conditions.

I would probably use original drake 46 for very marginal conditions and for figure of 8 slalom if the legs are short (when I need more upwind power then top speed). Is it good enough for that?
When the drake 46 is to big / to slow, I would like to switch to deboichet for the best top speed and ultimate control in extreme overpowered conditions. I need big range because my next sail/board is 6.7/is101.

One more question...Do you thing that is122 would be good also with 6.7 and sl4 37cm? Is it a good combo for flat water and very gusty conditions when the gusts are to strong for 8.2, and when is101 is to small for lulls?

I tried original drake 46 yesterday with 122/8.2 in light winds.
I don't like this fin at all. I had the feeling that it can not lift the board enough. I do not know about the speed, but planning thru lulls was also bad...

So, I decided to get two fins for this board. One for fullpower 8.2 conditions, and one for light wind and good upwind performance (for figure 8 slalom).

What model/sizes do you recommend?

Canfire from Vector fin... www.vectorfins.com
Sizes 42 to 46 or 48.

Sorry, deboichet only.

Debs are about the only fins that you can buy and then sell for about the same price if you do not need them anymore.

Sorry Vector fins are the same thing just better in your pocket. :)

I like the F-8 Tomcat Slalom fins by Tectonics. I have the 42 on my iS 111 and use it for 8.5, 7.6 & 6.6 sails. NO spin out and if you do push it out, it immediately pops back without pulling the tail of the board back in.

They come in sizes from 38 - 44. Less expensive than the Debs.

Debs are very performing Fins, but you need the right size in the right conditions...
For a big range Tomcat, Canefire are probably better choices.

Overpowered is done for the SL2 or the Rockit.

SL4 Only for top speed & DownWind, if you want a Deb prefere the SL2 if you have lulls & UpWind

Papounet, which sizes of SL4 have you used on which board? How did you find this fin after testing against SL2?

For a given contitions, which fin will perform better (top speed/range/upwind/control) - SL2 or 2cm bigger SL4? For example, do you think that I would still lack upwind and power if I take SL4 44 instead of SL2 42?

I have SL4 34 and SL2 36 so it is hard to compare for me... I like both fins very very much, and I do not find SL4 to lack power.

Nonopr, did you find any differences after testing vector fins against deboichet?
Which models did you test in what conditions?

A lot of informations from a lot of users here : http://www.windsurfing33.com/forum
but generally in French...
Some extracts ( first in english )

Hi Marko,

As you know we test a lot different fins here and until now we prefer the Deboichet line for the iSonics and are testing new fins for Futura.

For the iSonic 122, I recommand you the SL4 line in 42 or 44 in rigidity 2. Their is 2 option now 1 for soft and 2 for more stiff. 1 is more for light weight.

Hope this can help

All the best

Thanks Remi!

I decided to go for 2 fins for this board because I found that original drake46 does not work well at all.

Do you think that SL4 42hard and Sl2 45 would be a good choice?

SL4 42 for fullpowered 8.2 conditions, and SL2 45 for underpowered 8.2 and for figure of 8 slalom?

Is there any new model which would be better then SL2? Maybe SL6 or R16?

Thanks once again

I'm about to place my order for 2 deboichet fins for my iSonic 122 2007 to use with 8.7 and 7.7 2 cam sails..
I'm 72 kgs, figure 8 slalom and free sailing mainly..

44 sl2 and 40 sl4?

Both sl2, both sl4? Or something else?

Last, rigidity 1 or 2 for my weight? Same rigidity for both fins?

Ok ok, that's all... for now! :-)

Hi Marko,

The SL6 is the most powerfull on with a great glide, so in my opinion the perfect one for underpower condition, R16 is very good but use it in more stable condition.

Hi Alexwind,

For 8,7 you should use R16 or Sl6 in 44 and for 7,7 SL4 40 in rigidity 2

All the best

Thanks Remi but you are a bit late :(
I already ordered sl2 45 and sl4 42hard for my is122.

Do you think that sl6 is superior to sl2? I went for sl2 because I wanted a very universal fin which works in many different situations (upwind/downwind/flat/chop...). Good choice?

Hi Marko,

Anyway is still a very good fin, but yes prefer the SL6 who have more glide than the SL2. You will be not disapointed with the SL2.

All the best
