Slalom quiver question
 
At 70Kg, I am geting a new slalom quiver for 2010. Sails are Hot Sails GPS 5.5-6.0-6.6.-7.3-8.0. Two main options:

(1) Isonic 86 Slim + Isonic 94 + big one (width 75-80)

Or:

(2) Isonic 86 Slim + Isonic 101 + big one


Opinions? I am inclined toward (2), but (1) has appeal (and it would be the best choice if I keep my Is-111).

Hi Davide,
my first choice would be 86 slim/ 94 / 122, but guess you could go with your 111. It´s big enough for the 8,0 and works great with 7,3. You cam put the 6,6 and 6,0 on the 94 and the 5,5 and the 6,0 as well on the 86 slim.

You could also think about to go for a 2 board solution: 86 / 111

Have fun,
Chris

I second 2 boards solution: my 95 kg mate uses 94 + 122 for several years now (he is even racing occasionally), I've tried it and had no problem covering most conditions with no gap. So 86 + 111 would work well for you with a crossover sail 6.6.
I don't think you need 80cm board - at your weight and with sails not bigger than 8.

Davide,

For a 2 boards quiver with your 70kg, I'd go iSonic 86 Slim (5.5/6.0/6.6) and keep the iSonic 111 (6.6/7.3/8.0): plenty wide with 8.0 max sail for your weight (planing as of 10/11 knots).

The iSonic 122 + 8.0 sail quiver is perfect for 85+ kg racer. I don't gain nothing in early planing between iSonic 111W68/122W75/133W85 with a 8.2 m2 racing sail + 48 cm fin combo and my 65 kg. For my light weight, the limiting factor in earliest planing is clearly sail + fin size, but not much hull width (69-85 cm width) or volume (102-170 L; the iSonic 101W64 + 8.2 m2 sail + 44 cm fin combo clearly needs a tad more wind to start and sustain the planing as of 10 knots of wind). For a medium or heavy weight, this is a different story of course...

Cheers!

Thank you all, and Jean-Marc in particular who is close to my weight.

Interesting observation about sail/fin as limiting factor. I have an old Mike Lab "boat" (ultralight pre-formula course board) and it has a distinct advantage with a 7.3. However 7.3 turned out to be too small for marginal conditions (I tried!) and I am adding back an 8.0: I was indeed wandering if the advantage ML vs Is-111 was going to be reduced by a larger sail. (I'll keep the ML anyway, it is a pleasure to sail in tiny winds).

I am sure the 86 slim will cover the CA 52 territory, and if it can take some of the place of the CA 58 I should be set. The standard Is 86 should give a safer overlap with the Is-111, but I am a bit afraid it would be a bit less easy than the slim in the summer 5.5-6.0 conditions so frequent in the Bay Area ... Wondering how much difference 5L make ...?

Davide,

If you can read french : test of iS86 Slim vs iS86 2010:

Or get in touch with Christine.

Cheers !

Davide,

I have two 2009 boards 86 and 111. And I'm exactly 70 kg like you. Going out in lake garda with 20-25 knots in early morning, i was expecting to use the 86 just a few times .... and ... it's two months that i use only this board (mostly with a 6.2 .. sometimes with 6.7).

Maybe it depends on the condition where you do windsurfing ... but for me it's just like this ... light wind: 111 with 7.6 or 7.1 ... and then 86.

Ciao

Not a great english translation, but readable. Christine has done a lot of very good reviews on the iSonics, very usefull.

I'd think that the 2 x board solution is best. iS86 & iS111, more time on each board. Theres only 4 litres difference between the 86 slim & 86. I think there like the 08/09 iS76 & iS86, the iS76 was a slightly different shape, a higher nose for rough seas.


Review by Christine:
It appeared me wise to test them together since carrying the same name.

The 86 is the same as the one of the last year that was our favorite flotteur to both of them. Of course, our navigation conditions itself there lend well, but she is exceptional. Therefore the 86 is the even.

The 86 slim has the same shape, but some liters of less in thickness: she has a lot of paces.

Used fins: Deboichet sl230/32 sl4 31/32 Tectonic goldwing 30/32/34

Veil: North Warp 5,7/6,3/7m

Slim: No change at the level of the inserts of straps, one remains on the position all on the back, external for the rear, internal strap for the strap before.

Christine:

Fos, N 15 to 25NDS, plan of still water to small clapot.

In navigation, this always is it same régal of nervousness without yawed, great check, I always like as much.

On the 86 "normal" I prefer to put 6.3 while on the 86SLIM, I prefer 5.7. Mast foot to 133.5 for the two.

The 30 goldwing appeared me a not very small one in the soft ones, the sl2 32 or the goldwing 32 go better when the wind is irregular.

To the stop, it is more better to have the 86 classics, necessarily.

Perfect to the jibe, always to the top in replacement.

The Jaï, N 20-25nds, plan of difficult water.

86 slim 6.3, 32 goldwing: I am surtoilée (deliberately to see!) I advance my mast foot to 135. Despite the work-site, the flotteur remains healthy, controllable, there is only at the jibe where I not myself some go out (the sail is really too big once unhooked of the harness and the plan of copious water, a hell). Water already is fresh...

Fabrice, slim, Fos by North 25 to 40 nds plan of still water to short lateral clapot. Veil North warp 5.7 + goldwing 32 The slim presents a superior check in these
conditions. The remainder is for him to the avenant: a régal.

Fabrice 86 classics, north warp 7M goldwing 34, N to Fos, plan of still water to small lateral clapot: the body is particularly performance, slipping.

Grazie Giorgio, very useful observation. Here in San Francisco there are quite a few days with conditions requiring a 5.5-6.0, no idea of what is the wind speed (I carry no anemometer nor check wind speeds) but they are solid overpowered conditions with 5.5 when I clock my best speeds.

Have fun on Garda, I miss sailing "our" Italian lakes.
Ciao
