sail for isonic 117 2011
Ive been sailing formula, from about 7 years, use FW 161 and 9.7 and 11 sqm sails.
Now from my last trip brought in an isonic 117 2011, and I am wondering in wich sail size I would have the best wind range. My plan is to use slalom when the wind is 18k... and above 25k just never happens down here. I thought of a non-cambered 6.7 or 7.2... not sure.
Also with the board, came a 48cm drake race fin, wich I plan to cut to about 44cm (sb recomended fin on the web site), any thoughts?
Could you guys help me out on this? I am 75kg

First of all, Isonics like more cambered sails.
A 7ish sail with your weight would suit much better on an ISonic 90 or 87.
The IS117 typically prefers more an 8ish sail or even bigger with your weight

What is it that you exactly want to do with the board ? race, freeride, cruise ?

If you want to cruise/freeride with it in 18 knots average with peaks over 20 knots, you'll get your hands full.
I don't say it is impossible, but then there are more comfortable boards. A lot depends on the water state, i.e. flat or choppy. I think that the IS117 with a 6.7 or 7.2 sail will allow you to plane starting from 13-14 knots with your weight.

The IS117 is something like my IS122 and use it often with a 7.8 as smallest sail. It feels very sweet and it covers a very wide range 15 - 22 knots, but I'm 87kg. Me too, I'm not a competition racer but I want to blast as hard as I "comfortably" can. Usually I use the 7.8 on this board when this sail does not work well anymore on my IS101 because of irregular winds. When the wind drops below 15 knots average, I use a 8.8 as largest sail on it.

Tks for your help bel... I came with this board cause it was an excellent deal... I know it my be too big.
I'll stick with you then get a cambered sail above 7.5. What sail, mean brand and model, do you use with it? I had a look at the np h2....
What do you think about the fin question?

Hi Carlos,

I'm using a 7.8 NP RS:Racing Evo2 with 4 cambers and a 43 fin.

I really have no idea what it does with a fin, cutting off 4 cm. The length will be OK, I guess.

The older IS122 can use a fin with a lot of lift and the mastfoot far behind to get a looser feeling.
Don't know how it is with the newer IS117. I'm sure that the team or other people can help you out with this.

Yep, it sure looks like that.
Holidays for everyone.

On monday, I was out with my IS122 + 8.8 sail and 48 fin in 14 knots average and peaks till 19 knots.
Nicely powered up !
Still planing when coming out of the gybes. Very nice with such a large sail.

The combination really rocks in these conditions.
