Which to chose with 7.8- iS 107, 117 or 117 wide

I searched for similar threads but didn't quite find one that suited my question.

I'm 87kg (I do a lot of gym and running) and wanted to buy a slalom board. My main interest in windsurfing are waves but when the wind is light I like to jump on a slalom kit some time and due to the really bad season for waves this year on my homespot I wanted to buy some slalom equipment for myself to be able to sail in weaker winds.

I already have a good boom and mast (460) as my brother rarely uses his kit so I use it more often and I wanted to make a low cost kit with just buying a slalom board and sail (with 460 mast the choice would be probably 7.8 as 8.6 requires 490).

My main concerns are:

1. What board should I buy to sail in flat/choppy/wavy (sometimes) conditions with 7.8 sail considering my weight (87kg)?

2. What range could I get from 7.8 paired with 107 iSonic, 117 iSonic and iSonic 117 wide? I mean what could be the smallest wind for me to get plaining in (knots)? I think that I have enough experience to handle the kit as this is my 13th season and I already tried some slalom and formula kits before and I really liked it. I also sailed a lot in light winds on bigger kits (also freeride rigs).

3. What fin should I chose for the board that would suit the 7.8?

4.Maybe I should buy a carbon mast extender and go for a bigger sail? (however the mast I have is X6 80% carbon (low cost option is the only option for me as mentioned before)? Will the carbon extender work anyhow with 80% carbon mast anyway?

5. Maybe some older model like the iSonic 122 would be ok for me with 7.8 (it would also be cheaper)?

Sorry for so many questions ;)

All Best!

Hi, I'm the same weight as you and I also like to jump ASAP on wave equipment, but as you can see in my signature, I have quite a collection of slalom equipment too. Else my TOW would be reduced to perhaps 20% of what I'm doing now.

First of all you need to decide about the border line between wave & salom. It is something personal.
Personally, I'm not interested in wave stuff when I need sails > 5.5 m2. Actually I only have 2 wave sails that I use frequently, i.e. 4.0 & 4.7 with 1 freewave board of 83L. I start using this equipment from +/- 22 knots and up to 40 knots. Below this I'm on slalom equipment. There are a few exceptions when the wind has the right direction for a few speed strips with dead flat water in my neighbourhood. Then I could also be on my IS87 with 5.7 and 6.7 in the same wind range 22 - 40 knots.

My 7.8 slalom (NP evo2) sail is probably my most used sail. I use it both on my IS122 and IS101, but mostly on the IS122. I almost always start using it on my IS122 and when I get too overpowered, I just switch the IS122 for the IS101 and the same 7.8 sail works again fine. For you the IS107 will be right in the sweetspot of the 7.8 sail.

The low end range will start from 13 knots average (bare minimum), below this you can forget to have fun.
The sweet spot wind range will be around 16-17 knots average, also depending on the water state.
The high end will be around 20 knots, unless you are an experienced PWA racer because those guys can hold on to this sail probably up to 25 knots and more.

Fin size for the IS107 will be around 40.

I heard that a carbon extender works fine on an X6 460 mast, but I've never tried it myself. It's probably not the most optimal. Anyway, If you also think about an 8.6 sail you should definitely also think about the new IS110. You will have a lot of fun in the 12-18 wind range with the 8.6 and in the 16-20 range with the 7.8.

I'm planning myself to replace the IS122 for the IS110.

Hope this helps.

I always thought the X6 has a carbon content of 60%? Perhaps I am wrong?

Anyway if you want a cheaper option but want the same fun why not try looking for an isonic 111?

Easy choice really 7.8/107/39 or 41 cm fin (Vmax or S12 in Select work well). Expect to get going easily in 13 knots and as little as 10 with good technique. 8.6/117 combo is good also, just depends on what wind range you want to have fun in.

BelSkorpio 12th June 2013 09:24 AM

Yes, the X6 mast has only 60% of carbon, but for the carbon extender they say it is not that important.

I'm afraid that in 10 knots it will be very difficult if not impossible to get on the plane for a 87kg rider with the IS107 + 7.8. For sure no fun and only downwind courses possible. It's even hard to pump my US147 + 8.8 on the plane. Normally I take my US147 + 10.9 in these conditions (8-12knots).

Hi mate, this is my 2 cents worth.
1. 121/122 and 7.8 ( better lower end).
2. Or the 107/ 7.8. ( better higher end).
3. Spend more dollars and get the 110 and an 8.6 with your extender ( I would also get a 7.8 and you you would have lower and higher wind covered).
Good luck with what you decide.

Cheers Ozi.

Thanks a lot Guys for Your replies. I've been thinking more of a low end equipment because even if there is not so mu h power for my 84 and 5.0 (18 knots) I still like to ride waves as I prefer riding to jumping.

Anyway. What is Your opinion on 117 with 7,8 or 117 wide? Aren't these boards too wide for 7,8?

Unregistered 12th June 2013 09:07 PM

Mcross19- this one is actually 80% carbon SDM i think the shorter ones are 60%.

I also consider buying 111 but I wondered how much different it is from 107 or 117 because I have no knowledge about these boards.

All best!

Must be one of the older masts.

Just make sure the IMCS is correct for the sail you are buying

I would absolutely go for the 117W over the 117. Det 117W is far better low end. And it will carry the 8,6 much better. It will go superbly with the 7,8 also.

I often use my 7,8 on my IS127 with either 46 or 48 fin in 12 m/s. Pulling the mast base a couple of cm back from centre and the board dances gracefully over the chop. I would guess the 117W will do the same.
