Remi Hi Mark H

Did need something particay to read your video?

Hi all

The 2013 UltraSonic 147 was develop with sails from 7.8 to 12m and think that every weight rider category can have big fun on it.

Have fun

All the best

Stargazer HEllo Chris,

Sorry for the late reply it has been quite hectic the last couple of days.
Thanks for the info .. the IS 127 surely looks interesting .. it's hard to believe u start planning in 9-10 knots
I'm still in between a really early planner as the US and the IS 127 ... my 7.6 Vapor next to the Maui TItan 9.0 would fit nicely on the IS as well I guess.
I do however think I'm going to have a big overlap between my Futura 111 and the IS127. The US however is particulary well suited for the light wind conditions and as soon as the wind picks up to 4 BF I'll be hopping on the futura.
But planning at 9-10 knots and I weigh 75 kg .. thanks you made the decision just harder :-)
Anyway u turn it .. bothe whether it's going to be the IS or the US they r going to plane faster than the Ray 145 [ although this one planes pretty fast as well]
Is the IS 127 hard to sail and do you really have to actively pump it to get planning ?

Chris Dimond Aus06 I've been enjoying my new 2013 iS127 and Severne R4 9.2m with a 49 Select. I'm 95kg, and can get planing on this in 9 - 10 knots. With max downhaul, I can still be out there in 15-18 knots+.

13-15 is sweet...

The early planing of this combination for my weight is sensational, and I'm still using it with a 'dodgy' fin. I've got a 50cm carbon Volt on the way for light wind, and also a 46 carbon volt to use with this board and my 7.8 R2 in 15-20.

Stargazer Dear MOP, yes I do have the same question too .. more even since my weight is 72-75 kg [ no clothes] with a wetsuit ..we are a lot heavier of course not to mention boom/mast/sail.
Is a ULTRASonic no overkill for me .. r would it just work .. is an ultrasonic not only for heavier riders .. do you need as many liters for 75 kg surfer to plane as quick as possible or is the width that makes the biggest difference?
WOuld an IS 127 not better for me. I currently sail a FAnatic ray 145 ltd [2011] with a 9m Maui Sails Titan and it gets big quickly. I just want to plane earlier and have more control in the gusts.
I know formula is the king .. but I wanna have lot's of fun to and a board that serves me well for years to come.

Pelegrin Today I was out with 8.0-sail on both JP SLW and Isonic 127 Carbon. The wind made planning with 8.0 but not 7.0. SLW was planing earlier than 127 and planning-speed was about the same.

BelSkorpio Good question. I don't know. I've never sailed an e.g. IS127/137. So I can't compare.

Perhaps Remi or Jean-Marc can answer this one.

My guess is that on reaching courses and typical PWA downwind slalom courses, there will be not much in it. Probably the US needs less pumping. On the other hand, in slightly upwind courses it could be a different story.

If I compare the US and Formula in upwind conditions, I find there is still quite a difference. Formula rules without any doubt.

MOP Do you think that US gives much better planing than 82-85 cm slalomboard in 5-8 m/s when biggest sail is overdrive 9.5?

What do you think of gybing performance of the US compared to slalom 82-85 cm?

Pelegrin BelSkorpio - You did well explaining!!! I did not count with bodyweight and the differense between freeride and Formulasiails.

Anyway I think the mix that US and SLW stands for is fantastic - so lot of fun planning in lightwinds! I was out today in 7-8 m/s with 9.2 and felt I was flying(!).

BelSkorpio Hi Pelegrin,

With my 87 kg, I probably plane even with my 8.8 in 5 m/s = +/- 10 knots. For sure in a downwind slalom course.

The thing is that I also want to plane upwind in 8 knots average. That also means regular lulls of 6 knots or less.
Therefore, I prefer a 10.9 sail. It's no fun to be off and on the plane, nor to have problems to return to the starting point.
On the other side, I don't like too much freeride sails that quickly overpower me when the wind picks up. I had before a 9.5 freeride/freerace sail which horrified me in stronger winds. I'm far more comfortable with my 10.9 Formula sail than with my former 9.5 sail, despite of the heavier weight.

I guess, it's all about the range and personal preferences.
