I'm interested in finding the GPS max speeds for 144,133,122 ,111,101 Starboard I-sonic's. Plus the sails and fins used to reach these Max speeds. 
I have a 122 for light to medium winds and will be buying a 101 later this year for heavy winds.
Cheers
HI Biabog I have the 122 and the 86. My best speed on the 122 is 31.6 with 8.5 and 46 Venom fin the 86 ive done 39 with the 6.8 and 34 venom.

Bilabog, I was just looking at this the other day, here is an interesting thread from the Starboard forumhttp://www.star-board.com/forum/showthread.php?t=5313
I think you can go quite fast on a larger board if the water is very flat and you your are sailing broad, so the answer really depends on the conditons. I have an i86 and am hoping to get a i122 soonish.
I did a low 31 on IS111 & 7.8M sail. I was new to the board and water was a little choppy. So I think with a bit more familiarity and finding a flatter spot in the chop it should be good for a few more knots. Although I would imagine that bigger sails would limit the top end speed.
Haggar is right, given smooth water you can make most boards go fast. I did a 35 knt run at Sandy Point with my JP Super X 118. Didn't even feel fast or on the edge, just smooth. 
I have a 2008 101 on its maiden voyage i got a 33 even on it since bumped that up to 33.5 the other day, both were with a Koncept 6.6 and a 28cm lessacher Chamelion fin, the 33.5 was very hard work as in the chop it was trying really hard to throw me off
Hi Vando,
So far I have only recorded 26.28 Knots on my 122 IS and 25.77 over 10s . That was with a 6.8 Arrows T-Force, Select Eliminator 32 Weed fin. Winds gusting up to about 18-20 Knots I think. Hard to tell. At the moment my largest sail is the VGM 7.5 which I have done 26.08 Knots in about the same wind conditions as above but the water had more chop. I'm looking foward to getting bettter conditions to try and brake 30 Knots!!They are very impressive speeds that you have done.
Cheers!
Hi Haggar,
I have only had my i-122 (2008 model) ,3 months now and I'm really impressed with it. It just wants to drive foward when the gusts hit you instead of trying to lift out of the water. I know you are really going to love one!
Hi Sausage,
My I-sonic 122 w75 is a 2008 model.
I have a Star-Board 2008 product catalogue with lists the 122 as 122 litres. But I don't know if that is the correct volume? Where I sail the condition change alot on the lake and the 122 is perfect. I was thinking of getting a i144 for the really light days and see what speeds it can do.
Back in '07 at SP in a NW near the car park on a '08 Futura 122 with Drake/PA 30cm wave fin, Koncept 6.6 2sec peak was just over 39,
Going on that experience it should do over 40 in a SW, ie flater water/better angle. A 28 sweptback speed fin would make the task easier though..
Further to what Spotty said - I've had my '07 122 up to 36 / 37 knots regularly at Sandy Point with a 33cm Select Lightning fin and 6.5 '06 Stealth. That has generally been on an Easterly or NorthWesterly - on a SW you could probably do better but I tend to change down boards as my 28cm fin is a powerbox & needs different board. I find the smaller fin means you need to get up a decent speed before really pushing - but once you get everything set-up right you just lock it in & use the board width to really leverage the rig.
... I gots another ten knots to get outa that lass!! Love the board and stoked to hear that it has such a high end. Next time it's flat and windy I'm going to do a compare and contrast with the 93L.

Hi Vando,
What is your body build? I am 1.76cm for 80 kg! Are you a big guy?
I have myself the 86iSo and done only 33.5 on a 6.7 and 26.5cm! The board feels big for me, and does not seem to free itself (maybe the fin)I never really used that board for speed, it is more like light wind board for me, also I always used weed fin because the 2 main areas where are sail got lot of weeds.
I may try one of days the board on Hardies run with the 5.8 and 25 fin. I noticed the board does not like fins under 25. (depend where I suppose)

Hi Vando.
I did my best speed today so far for my 122 IS : 28.34 Knots and 27.33-10s.
It was a ENE about 18 knots. I used a 7.5 VGM with a 32 cm Weed Fin.
Board felt like it wanted to go faster but not enough wind.
I have only used this board several times, I've been using a RS 6.7 with a 34 cm Venom and its performs great, also used a 30 cm Venom which has felt a bit quicker. Best peak speed so far is 33.9 with the 34. I just love this board

Hi Sam, Im prob abit heavier at 85kg 178cm tall. On the IS86 I run the straps in the middle posi and mast track pretty much on the recomended marks.
26 fin is prob to small for the IS86 and 6.7 I wouldnt use less than a 30 ulness your sailing at sandy point lol.
ta Vando
Thanks Vando for the inf... appreciate
Same as you for the straps and mast but was thinking to move the strap at the back on the last one and keep the front at the same pos, to try to free the board and more control over it (g that board feels big in high wind!)
For the fins I have been using anywhere between 25/35 deg and 34/43 deg, using 5.8 and 6.7 RS and depending the water surface.
I have not try the board on the run yet and the max fin there is 25/40 to 45 deg, anything else is not save 
I tried the other days a Lesh_Cham 24/45 deg with 5.8 RS, due to too much weed at SBay...weeds was sticking to the fin caused by the concaves on each side! Beside this it felt just right on the limit (the surface is probably egal to a 26cm)!
But I have to say that C3 profiles works perfect for the 86L 
but need to be bigger sizes!
Anyway I ll be trying the next few days the iSo on the run and post back here if any better that 33.5.
Thanks again
Sam
Sorry Bilabog, you was asking about all the iSos but the 86!

Sam, I have the i86 and am about 80 kg when I have drunk too much Guiness I have only used this board several times, I've been using a RS 6.7 with a 34 cm Venom and its performs great, also used a 30 cm Venom which has felt a bit quicker. Best peak speed so far is 33.9 with the 34. I just love this board
Thanks Haggar, bit like me then... I have to try harder I think 
gg you guys over there are all using C3s !
I got the feeling that the 86 with a 30cm and a 5.8 on flat water will rocket...
eh Vando, a 39 with the 6.8 and 34 cm thats awsome speeed! I don't know how you do it! I though only heavy guys could achieve those kind of speed with the 86.
Hi Vando,
The lake where I sail changes alot depending on wind direction for weed. I do have a 43 cm select Race pro weed fin. I might try that next time then the weed is not so thick on my 122 IS. I used it once before but the weed was catching on the fin.
I have found the 45% Select weed elminator fin being the best so far in this lake.The guy I sail with has tried a Maui weedburner in the lake and it was picking up weed. I wish some one could make a weed fin that was ajustable so you could change the angle while you were out on the water.
Vando where do you mainly set your mast on the mast track on your 122 IS ?
Hi Romas,
That's just over 28 Knots. That's really moving for a big board!!! How strong was the wind when you recorded the 28 knots & was the water dead flat?
Big kit can go fast. been pushing my SX XL. Still have not found it's top end
gpsteamchallenge.com.au/sailor_session/show?date=2009-02-13&team=2
32knt 2sec peak.
Kit was a SX XL (135Lx235cm long x 80cm wide with a 7.2m RSS MKII and a 40cm weed Choco)
Hi Bender,
Great speeds for the big rig. Fantastic pictures from the helmet cam.
What Brand & model cam is that? I'm thinking of buying one soon.
