View Full Version : Isonic 150 vs. Isonic 133

18th June 2009, 07:24 AM
Remi sure likes the Isonic 150. I've never sailed one, but I've sailed the 133 and quite often against the 133 (recreational sailing) and I'm very impressed! Does anyone have experience with both or with at least the 150?

I am beginning to suspect that Starboard hasn't sold a single Isonic 150! If it has then that one person either isn't willing to talk about it or doesn't read this forum.

I saw a 2nd hand iS150, a white "none wood" version on friday at my local WS shop. Did realise SB did a non wood version. It looks much wider than my iS144 in the flesh than the numbers suggest. Its also much thinner than the iS144. I opted for the iS144 as it was thicker, I just felt that light wind pumping would be better CW a thinner board. Heres a link with pics of an iS150.

Thanks for the link - just wish my French was better.

Hows this. Not the best translation, but readable:)


The tail thickness is on-parr with an iS111, so its quite alot thinner than an iS133/144. This was the only thing that bothered me about the light wind performance off the iS150. I could be wrong, but my feelings are that thicker rearward sections will out perform thinner sections. Other than that, the iS150 does look "one size" bigger than the iS133/144. Although Im a bit sceptical about thin tails on wide tailed boards, Remi has assured me that the iS150 will plan earlier and feels more powerful CW the iS144/133. I'm still thinking of switching to an iS150???

Hi Grant,

If you want to use 10 and up for sure this board will be the best one and also will be more easier, jibing will be better also with a very good exit.

All the best

Thanks for the comment Remi. The sail range I'm looking at is basically 8.5 to 10.5. I'm assuming 10.5 is a little big for the 133 and 8.5 a little small for the 150. Which is the better compromise - sailing a 150 with a 9.1 or sailing the 133 with a 10.5? Does the 133 have a distinct advantage when an 8.5 to 9.5 is used? Thanks for any response.

Hi Grant,

We use just to compare in Formula Experience 7,5 on the F 160 and this work perfectly.

The iSonic work great also with a 8,5 but will be less easy in choppy condition compare to the 133. But for sure with 10,5 the 150 will be much better than the 133 and alos the insert position are not the same, less extrem and more confortable.

To help you in your choice just think how many hours you will have on your 10,5.

Hope this help

All the best

If my largest sail is a 9.0, and I sail in fresh water, is the 122 big enough?

yep, plenty big:)

not so fast mark...

It depends on your weight and what you want...

For riding (racing) yes...but if you are about 95kg and more you can forget uphauling and you will be suffering when the wind dies...

Ciao M.
PS: remember 122 actual volume is somewhere 113 liters...

Hi Mim, good point and very valid. My take on this is:

I'm 105kg/194cm and used to be able to uphaul a 9m warp on my old 125. The 9m/125 was a real nice combo from 10k to 20k.

I replaced the 125 with a 111 and also find this no problem to uphaul, but admitedly, you have to "snap" uphaul and avoid doing it slowly (especially in chop/swell). I now prefer the 111/9m combo.

I understand that from time to time the wind does die when we least expect it, (& what pain it is when it does this), but no one usually rigs to be under-powered, so water starting shouldnt be a problem. I guess if possible, keeping an eye out for dying winds is best.

What I'm trying to say is, dying winds are a bigger problem in some areas, but if its blowing 30 knots, most people would take kit best suited to the conditions, not bigger in case the wind dies. Other wise, we would all be sailing on SB Rios all the time:)

Just my 2 cents worth

Sure you are right...with plenty of wind there is not a problem for uphaul or waterstart.

You know, the problem is when there are two weeks of no wind...you take what ever comes...and sometimes there is just a few knots...and the frustration from not surfing just kicks you on the water even though it is obvious that when the wind gets weaker just a little bit you will not be able to watterstart and if you have abad luck the wind will die totally.

PS: me personally, for such conditions I have iS 144...where there is no problem at all.

Ciao M.

Hi Grant
I got my iSonic 150 2 weeks ago and finally after few days of right wind conditions
I can tell only good about a board. I am also ~95kg, so i.e. 2 days before I was
sailing in 18 knots with 9.0 and board was very good.
