Default IS80 or Speed Special 54 ?

I am looking for a speed/slalom board for high wind, my weight is 62 kg. Local conditions are usually flat to small chop. Sail size 5.5 till 7.0. Has anyone tried both boards ? I would love to hear the main differences in performance. Top end, range and ability to handle small chop. Thank you.

Hi Frederico
If its only for speed sailing in flat water to small chop better to go the iSonic Speed W54, the iSonic 80 is a fast machine for slalom in any water condition.

Hope this help

All the best

Federico,

If your main goal is to go as fast as possible with your light weight, I would strongly recommend to get the speed board. I'm 65 kg and have been using the iSonic Speed W53 with mainly 6.6 and 7.7 m2 sail, wind range 12-25 knots of wind. This is a great board from flat water up to medium chop with 50 cm swell. The biggest speed difference with regards to a pure slalom is when going downwind at 120-150° : the true speed board has a really big advantage for a light weight rider with her overall smaller "footprint", smaller tail block, smaller fin, reduced lenght and swing weight, reduced volume and lighter weight. There is no limits, except that of the pilot himself. If I would buy again a speed board, I would pick up the W53 (or W54) without question : she's a true gem with 7.7 m2 sail and ±30 cm fin.

If your main wind range is 50% with 5.5 m2 sail and 50% with 7.0 m2 sail, I would pick up the iSonic speed W49 board because of your light 62 kg weight. You obviously want to get the smallest gear going in full control at full speed with a 5.5 m2 sail in ±30 knots winds. In those high wind conditions, excessive volume is just an useless balast. However, if your main wind range is 20% with 5.5 m2 sail and 80% with 7.0 m2 sail (or more), better get the W54 for medium to light wind speed sailing.

Finally, if your main goal is to win slalom runs in any water condition and keep top notch control during jibes, I would choose a dedicated slalom board ŕ la iSonic 80. Higher scoop-rocker line, wider tail block and softer rails all do enhance her jibe control and speed exit quite significantly. The more difficult and severe chop it gets, the better the iSonic 80 goes.

I'll ask Christine from the french forum to churn in and let her to tell us what she's experienced with her light weight 62 kg.

Cheers !

JM

Default Thank you jean-Marc,

Thank you for your reply. It almost makes me go with the IS80 and W49 combo for medium to high wind. By the way, have you tried any of the wide base fins that are in the market ?

Great advice from Remi & Jeam-Marc. The iS80/W49 sounds like a good option. Or, If your sailing in proper speed conditions, then W44/W53 would be best. If you want just one board and you have just small chop, go with W54, but get two fins, one small speed fin (25cm wide base/23cm Assy etc) for perfect flat days and a second more control fin for chop (Tectonic F1 Falcon 28cm).

The 1st generation wide base fins are doing very well now. I switched from normal speed fins (Assymetricals, raked etc) to Tectonic Nomads (also tried C3 Slingshots) and I love them. Regular speed fins have great top speed potential, but they also have a very narrow sweet spot to be be in the 100% range. This means you need at least 3 or 4 (or more) fins per board to be at top speed all the time. No good in gusty locations, as super tuned fins can not cope well here.

Wide base fins are 95% as fast as specialist speed fins but they have a massive sweet spot range, so you do not need so many fins. They are fast on tight courses as well as super broad courses (110_150 degrees), also good enough to get back to the top of the course and pretty good through rolling chop at the bottom of the course.

Since I switched to wide bases, my PB's keep going up. recently got half an ants testical shy of 44 knots in not great conditions on a Tectonic Nomad 21cm. I am normal speed sailor, and wide base fins are made for normal speed sailors to go super fast, easily, in big range, on all angles, in most conditions (even in not good conditions) and to be safe (spin-out free).

You have a great choice of wide base fins, Vector, Tectonic (my favourit), Sonntag fins, Curtis, C3

You can probably tell I really like

Thank guys, for your input. I decided to go with IS 117w, IS 97 and the Speed Special 54. BTW, anyone has experience with Severne Reflex III's ?? Are they suitable for a light weight rider ? ( I am only 60 kg.). And what brand and sizes would you recommend for this board ?
Thanks !!

Federico,

Interesting, we almost have the same speed-slalom quiver:

- iSonic speed 53 + 6.6/7.7 m2 sail; fin range 26-32 cm; wind range 12-25 knots.
- iSonic 117 Wide + 7.7/8.2 (8.6)/11.0 m2 sail; fin range 40-54cm; wind range 7-18 knots.

As for sail, I cannot comment on Reflex III but I do have a Reflex II 11.0. A lot more tender and softer than a 2007 Code Red R2 11.0 m2, so I have a much better control in the high wind range (+12 knots steady wind with gusts peaking at 15 knots for my 65 kg).

The Code Red 7.7 m2 sail is a perfect "switch" sail between 2 boards size. When I'm well to overpowered with the speed gun (15-18+ knots wind), it's grunty and slippery enough to go fast without too much effort. When the wind starts to fade a bit and gets more holey (say 10-18 knots), I just swap the speed gun for the iSonic 117 Wide and off I blast again with the same 7.7 rig. Just did 1 session so far and I was very pleased by the ease and control of such a wide board in the upper wind range for my light weight.

At the other end of the low wind range spectrum, I'm very happy with the 11.0 sail on such a board. Sure, she points quite less upwind than the HyperSonic 105, but she's fast, accelerate steadily and jibe faster. Like my old HS105, the iSonic 117 Wide felt clearly 1 size smaller than the iSonic 127. I'm sure you can't go wrong with the iSonic 117 Wide, even for a light weight rider...! Keep us posted of your progress report so we can share our light weight rider's experience with such a quiver.

Cheers & enjoy your fast ride !

JM

Thank you Jean Marc, I will keep you posted. I am considering a switch to a new sail brand. From NP EVO's (I have been with them for the last 8 years) to either: Reflex's, Vapor's or Maui Sail's TR8's. I would love to get more input on them, specially from guys in our weight category. Thanks, JM.

As a lightweight also (68 kg) I use my combo I Sonic 107 and Speed W54 with The Loft Blades on RDM masts, an option to consider!
