Hi,

I want to buy a early planing Isonic above my Isonic 122 ( 2008, 114 liters ).
I'm 87 kg.
I'm now surfing with:
* Isonic 105 ( 2006 ) with Tushingham X-15 sails ( 6,4m and 7,6 m )
* Isonic 122 with Tushingham X-15 7,6 m and with a Tushingham Lightning 8,5m
* Falcon slalom 145 ( 2007 ) with the Tushingham lightnings 8,5m and 9,4m.

I want to change the Falcon for a;
* Isonic 131 or a isonic 144.
Or must I go for the mini-formula Isonic 150?
In the past I have had a starboard Formula 159.
Nowadays I don't like the big formula boards anymore ( to heavy and to exhausting :o) .

Can you advise me.

Regards
Maarten

Hi Maarten,

Is it for race or just for fun?

All the best

Hi Remi,

The new isonic is just for the fun.
But I don't like the the formula style of surfing.
So I'm not sure about the isonic 150

Remi,

Not only the upwind qualities are very important for me but I also want to be fast in downwind runs.
I think that in lightwind conditions ( 9-14 knts ) the Isonic 150 is much slower than the 133 or 144.

I like my new 131 iSonic. It is a super good board for light wind slalom for sails up to 10m. But also has when the right fin is selected great upwind ability, not formula like but enough for me to go up wind from one spot to the other no problem.
I think is the best boad I have in my quiver so far.

I'm still waiting from the answer of Remi.
My biggest sail is the Lightning 9,4m.
Is with that sail the early planing qualities of the isonic 150 so much better compared with the isonic 121/144 ?

You ask for advise.

Sorry nonopor. I appreciate your comment on the isonic 131. I think it is a good early planing slalom board for me.
But my next question : Is the isonic 150 not better for me considering the super early qualities of this board. Or is there not so much difference between these two boards for early planing with a 9,4 m sail.

Regards

In my opinion a 9.4 sail will get a 122 going in that wind, but the 131 will hold it better and stay on planning speeds better. I have never use the 150 but I have a formula board that is about that same size a Mistral Devil and i think the difference will not be worth it.
Yesterday we had a graeat day here with less than 11 knots of wind and I was on my 131 with 8.0m sail an got it going and my friend was in a 133 with a 9.0 and he was going also. I wont buy a 150 for slalom. The reason is that the board was design just for crusing as the PWA rules dont allow a board that wide. I dont think it will be faster or any better than the 131. That is my opinion.

I have had the iS144 for about 12-months. This replaced my Formula 159. I have found that XXL slalom/10m needs about 3 or knots more wind than formula/11m to get going.

In both of their wind minimums, the formula feels more powered up. How ever, once the wind fills in to 12/15k, XXL slalom starts to feel faster, my GPS showes this to be true for me.

In really light thermals, I missed formula, so I was going to change the iS144 for either an iS150 or get another Formula.

I recently borrowed an 08 iS150 from my LWS for 3-weeks. I tried the iS150 with 9m, 10m & 11m. Its good with all sizes. Fins from 51cm to 58cm tested. Smaller fins give much faster top end and 58cm fins gave it "mini formula" feel. In non planing mode, the iS150 feels much bigger than the iS150 and its easy slogging with an 11m. Once planing, it still feels much bigger than the iS144. One thing I did notice was that the iS150 feels smoother over chop C/W the iS144,this is due to it having thinner rails. The iS150 footstraps are slightly more in board C/W the iS144 which I did not like, but other may prefer this.

I personally really like my iS144 with a 9m and 51cm fin and hesitated to sell it. So I opted to get a good second hand Formula 161 for 10m/11m and keep the iS144 as well. I bit of a luxury having two light wind boards during credit crunch times, but the iS144 and F161 are two totally different boards, both are diamonds in different areas and its hard to choose which way to go.

I guess if you want "one board" to enter both area's, the iS150 would kinda give you the best of both. But not Diamond, more ruby:)

As you already have a very good light wind slalom (iS122), I think the iS131/iS144 will give you way to much cross over. So you should really consider the iS150 as the only sensible option. Has I said earlier, I was really impressed with the iS150 with a 9m/10m/11m. It only needs about 2 knots more wind than a formula, is faster in 12 knots and above, and eats chop (for such a big board) and its thin rails make it jibe very well (again for such a big board). If I would not loose a lot of money on selling my iS144, I would definetly have gone with the iS150 instead of an iS144 and Formula 161. In the future I may still do this???

I just wish that SB had made the iS150 95cm wide as it could have been classed as a "formula" in the GPSSS.com formula rankings.

Sorry for the extra long reply, but some times there's just no simple answer to these questions:)

Thank you Mark for your answer.
I agree with you that the isonic 131 cross over the isonic 122.
But I don't like use the 9,4m on my IS 122 ( better suitable for my 8,5 and 7,6 m ).
The Isonic 150 what you say feels big and with a big fin it feels like a mini formula ( wath I don't like )
And I'm not so heavy as you are ( I'm 87 kg ).
So perhaps the Isonic 131 is still a good solution for my problem.
Selling the isonic 122 is not an option ( I lose too much money ) .

Just to clarify. The iS150 does feel smaller, faster, easier in chop C/W a F159 or F161. It only feels like a mini formula when 58cm plus fins are used. I used up to a Deb R13 64cm on super light days and felt like I'd gone into formula mode. On 10/12 knot plus days and using a 51cm to 54cm it felt much more like a XXL slalom. I feel it can be switched from "almost" formula to XXL slalom with a simple fin change.

Hi Maarten,

I'm also 87 kg.
From 12 - 15 knots, I use a 125L board with sails 7.5 & 9.
I'm a recreational surfer, but with a combo like this in those conditions, I don't see many guys passing me.

I find that once the wind drops below 12 knots, I really can use all the volume I can get.
In these conditions with us at the North Sea, the wind is also very often not too stable anymore.
It often happens that I start sailing with 11 knots while half an hour later only 8 knots are left. All averages of course.
To be quite honest, in these conditions, I'm not interested anymore in speed BUT more in keeping the board planing comfortably.
The board that helps me the best with this is my SB F161 with 11m sail.
It helps me pointing when the wind gets a little stronger to recover from down wind racks when te wind gets a little weaker.
Again, planing in these conditions is really what matters to me the most.
If you say that you dont really like Formula equipment, then it seems to me from the experiences of Mark H, that the IS150 is your best option.
I'm actually also curious to try that board one time and compare it with my F161.
On the other hand, I dont think I need anything in between my 125l board and the F161.
