Default gain in early planning 8,8 to 10,0 for 82 cm slalom board

Hi,

Sorry for a non-starboard related question on this forum.....

I have a 135 L 82 cm width as my biggest slalom board. I have 8,8 as biggest sail for it and a 49 cm fin.
In the summer where i live we often have quite light wind and it is often that the 8,8 feel just a little bit to small.
I wonder if I would gain a lot of early planning potential by adding a 9,8-10,0 sail and of course a bigger fin?

My weight is appr 98-100 kg and I compete on national level in slalom as well as some local competitions.

I've asked Kevin to comment when he gets some time after the racing.

I notice a big difference between an 8.5 and a 9.5 for light wind slalom. The difference is evident when the winds are light and gusty. You may have to pump your 8.8 like crazy to get going when a 10.0 (assuming your board will carry it comfortably) will pull you onto to a plane with little effort. You may be able to plane through your gybe with the 10, but not with the 8.8. In conditions where you can plane easily with the 8.8 I don't think a 10 will help much unless there are some really big holes. The extra grunt of a 10 is only worth it for those really marginal days, but definitely worth it since it will turn a non sailing day into something worthwhile. Once you get beyond a 10 it gets hard to justify unless you're a super heavyweight.

thank´s Ola and Deja vu!

I do not want to go bigger than 10 m2. I have been doing formula before but does not enjoy it that much.

For sure, you will notice a big difference from 8.8m to 10m. I'm similar weight to you (105kg) on an 85cm XL slalom and feel a big benefit when I switch from 9m to 10m (and bigger fin). Pumping is easier, faster exit out of jibs, better acceleration, better angles up/down wind and generally feeling more powered up. In fact, 8.8m is about as small as you should go on an XL slalom, is yours a JP Slalom 82?

Hi Mark,

No, my board is the Naish SP 135. What size of fin would you recommend for a 10m2?

Mark H.

What do you think of your Is144? I've sailed the Is133 and find that it is one board that is actually better than the hype! How does our IS144 compare to the big JP Slalom V and some of the other big light wind slalom boards? Sorry for the off topic post, but I'm really curious.

I would go with a 10 or the 9.3. For us on the PWA we dont usually use bigger than the 9.3. For you in the light wind you can go with the 10 if you are not racing and just want to be planing early. HOpe this helps.

Kevin
