View Full Version : Best Isonic in between F159 and St 126

14th January 2009, 01:03 AM
I have a Formula 159 (+ 10.3 freeracesail) and an S-type 126 (+6.5 freeridesail, the 126 doesn't really work with anything bigger than 7.5).

If I - 95 kgs experienced - want an Isonic in between these two boards what will any of you recommend? I will primarily use a 8.5 freeracesail with the board.
I don't compete, and I sail in quite gusty conditions....


2007 or 2008???

All feedback is very welcome.

Either would be good and both will work with your 8.5m, but the iS122 will feel best in 8.5m mode. 07 & 08 are both nice boards, but the newer the better. Your ST126 should feel good with a 7.5m. I'm 105kg once borrowed an 06 ST126 to use with a 7.8m race sail. It did feel like it would take a little bit more with a larger fin. But this might just be my preference.

The only prob is that you will end up with 3 light wind boards!! Although they have different briefings, the iS111/iS122 are very near to your ST126, and the iS133 will be for just one sail (8.5m), a bit of a luxury I guess. I wonder if it might be worth considering a more even spread between your boards.

Maybe sell/PX the ST 126 and replace with an iS111 for 6.5/7.5/8.5 then jump onto the FW/10.3m there after??


Keep both your FW & ST, dump the 8.5m and replace with an NP Helium 7.5 for light wind ST126 days and get a powerfull fin??

My 2 cents worth

Hi Mark
Thanks. Well, the ST 126 isn't really a light wind board. Though 126 litres the tail width is only 41 cm (only 1.5 cm more than Evo 100 - the IS 122 is 13 cm wider in the tail). This makes it a very loose and great blaster with my 6.5. It can carry bigger, but then it gets a very locked in feeling which it's not really made for.
I guess you're right. The F159/IS133 gap is a little too close. Almost same wind range.
Maybe it should be F159/IS122 and then switching the 126 to something smaller...??
I don't know if the IS 122 will work with a 6.5 for recreational blasting??

Hi Per, the ST126 was my light wind board, an excellent one by the way. But at 95 Kg and with 8+ sqm sails you probably need fins in the 45~48 cm range, and it's too much for it. The gap between 159 and 126 is too small. The Futura 122 (47 cm OFO) will probably carry a 8.5 better and work with your 6.5 as well.

Hi Per, I have a IS122 2008 and at 85kg have used a 4-cam 6m6 on it with a C3 Venom 38 fin to peak at 31kn gps - not too bad at 50+ years. But, I find it all comes down to sea state - those runs were on small inner harbour wind chop - as it gets to true 6m6 waves then the IS122 is way too big to hold down (and slower with control!).

I've also used 7m0, 7m6, 8m2 and 8m8 Naish Redlines/Stealths on it too with Venoms 42 and 46. 7m0 & 7m6 are fast in the right sea, but I feel a smaller board would be faster ( I'm planning to add an IS94) - for me 7m6-8m2 optimises the planning/board speed at my recreational level while 6m6-8m8 hold their own challenges!

Hmm... If you want to keep both your current boards, I think the iS 133 or futura 133 would be the best fit between them.

Or if you want to replace the S-type, I'd get a futura 122. It should have more range than the S-type on both ends.

For really windy conditions you could get a cheap secondhand board around 100 liters, since you won't be using it often.
