Hi!

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.

Cheers.

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.

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?

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.

The 117 or 117W will take the 7.8 no problem. If you want to use an 8.6 I would go 117W.

If you're looking for a light wind kit, here is a simple answer to a simple question : best board for best sail and best sail range :

iSonic 110 : 7.8. Range 7.0 - 8.6
iSonic 117 : 8.6. Range 7.8 - 9.6
iSonic 127 : 9.6. Range 8.6 - 10.x

I have an iSonic 117 Wide and I can confirm that a 7.8 m2 sail is fine, even for my 65 kg light weight up to 18 kts of wind. So I'm sure that it would be no problems with 20 kg more body weight to keep her flying above chop at full speed.

I also doubt you can start and sustain the planing as of 10 knots with iSonic 110 + 7.8 sail combo for your 87 kg. I can do that on iSonic 117 Wide but I need an 8.6 sail. I need more wind for sure with a 7.7 sail.
So, if you really want to enjoy blasting in 10 knots winds, better look at iSonic 127 + 9.6 sail combo IMHO. Several of my 80-90 kg buddies are using that kind of kit and we are on par when doing drag racing as of 10 knots of steady wind despites our 20 kg body weight difference. A 7.8 sail is definitely way too small in such light winds.

The 107 is the successor of the 111. Same width, probably almost the same volume. Starting from 2011, all boards carry more precise volume specs.

I agree with most replies above, i.e. if you're aiming for the lower end, then forget about the IS107 (or 111) but go for the 117W (80cm) but also go for a bigger sail next to the 7.8, at least 8.6 or 9.5.

Thanks guys, Your replies helped me a lot. the last question is what fins would You recommend for 87 kg with 117 wide with 7.8 (what fin for stronger and what fin for lower wind) and also for 8.6.

Please tell me the lenght and if You have some tested brands and models.


All best again and thank You very much!

44cm for the 7.8 and 46cm for the 8.6 should do it.

I agree with the above comments, but I'd skip the IS122 and get the Is107 or the IS110. I have experience with both the 122 and 107 and IMO the 107 is a much better board. I have the IS110 on order so I'll have an idea how it compares with the 107 shortly. If you can find a used 107 and a 127 or a 97 and a 117 wide for roughly the same price as a new Isonic then I would go that route. Buy good used sails from sizes 6.2 to 9.5 (6.2, 7.0, 7.8 or an 8.2 and a 9.2 or 9.5) and you'll be covered for most "normal" conditions. If you're willing to look you can find great used equipment or a fraction of the price of new.

Hi Deja Vu,

May I ask how much you wheigh ?

Either way, I'm very interested in your findings on the difference between the 107 & 110.
Let us know.

Thanks.

I'm 180 to 185 pounds (82 kilos). I sail relatively flat water and the 110 should fulfill my needs better than my 107 (which I really like). It took awhile to receive the board, but was worth the wait. The 110 is fast on a reach and is extremely good upwind and off the wind. IMO there's no comparison between it and the 122 -- I like the 110 much better. I have the carbon version of the 110 and it is extremely light and feels very responsive on the water -- definitely a keeper.

It is my impression that the 110 has a more "formula" feel to it than the 107. This could be good or bad depending what you're looking for in a board. I've owned and sailed formula boards and it seems to me that Starboard has successfully combined many of the positive attributes of a formula board in a relatively small slalom package. The downside is that the 110 appears to be a little tougher to control in overpowering gusts. I would chose the 107 in big winds if my only other choice was the 110 and the 110 over the 107 for all other conditions.

The footstrap setup on the 110 is quite radical -- the rear footstrap is located right on the edge of the rear winger. For anyone used to the Isonics this won't be a problem. Also the deck concave on the 110 is more spread out and this makes it easier to insert the mast foot and twist it to tighten it down. The deep Tuttle box for the fins is a nice touch and it will easily take both deep and normal Tuttle fins. It comes with four screws for the fins (two longer ones for the normal fins and two shorter for the deep fins). Where you insert the screw is still recessed like the 107 so the tail must be pretty thick to take a deep Tuttle fin and still have the screws lowered into the board before you tighten them.

I'm not sure if the tail cutaways, the double wingers etc. actually effect the board's overall sailing characteristics in a positive way, but they sure look radical and the 110's performance is very impressive.
