Hi Floyd, overall width plays a role indeed, but OFO and kick/rocker line probably even more.
Futura's are wider than S-Types of similar volume but I wonder which ones are really faster.

For the sailing for pleasure windsurfer there is another factor to consider. Some boards FEEL fast without necessarily being so, and some fast boards DON'T feel so fast, even though they are.
Since I don't race, give me the feel fast boards . They'll still be able to keep up with the pack at our beach. (A bit of 'trying hard' can usually keep the others roped in! )

Wonder how many other sailors have similar experience to Per ???
We take it for granted that dedicated slalom kit is faster and without doubt looking at fin and width of them compared to equivalent volume freeride they are bound to go up wind better but I`ve not seen any increase in my Vmax over past 4 years on 120 ish litre boards even though I now sail a dedicated slalom board. I`m sure my VMG is better but my Vmax certainly isn`t !!!
Suspect problem lies with comparing boards of equal volume ??? Perhaps a 120 (ish) litre freeride should be compared with a 100 litre slalom (equal width ???). I think it would be a different story but problem is I just dont feel confident enough (with the wind) to go off out on a 100 litre slalom knowing iof the wind drops I`m swimming .. For me I suspect the bigger (buit narrower) freeride gives better Vmax than the slalom board I`d have to sail (do sail)
Perhaps there`s a market for a salom type performance board but with a safety margin of volume built in. (Was it the S type ???)
As for my speed board; it got used twice last year !!! Sub 80 litres + offshore winds + no rescue ????? I`m sure it would be faster ?????

The Carve 145 wasn't slow. It used to win a few slalom races some years ago. And that's one of my points. Modern freerideboards aren't slow or low tech at all. I doubt most riders would be able to squeeze more than 10% more speed out of a slalom board compared to a good freeride board, but those 10% make the whole difference on the racing course. It's not like comparing a family car to a formula 1 racer.
Regarding the iSonic 122 I use a Tushingham Lightning freerace sail, give it plenty of downhaul, loosen it a little on the boom, straps back and out, mast foot in the middle.
Nice, fast and controlled set up and I can really max it - no problem it's a lovely board, but I haven't cranked 30 knots yet ( I sail in quite choppy conditions) as I did on my Carve (which I sailed a LOT!!). Probably it's a matter of time on the water.
It will come though, and I believe the iSonic is capable of +33 knots with my ability.

|Unregistered||You must be ridding the isonic wrong cause iS way fast than carve 145, no doubt about that|

I was generally able to do one knot higher GPS speed on my old Carve 145 with a 6.5 no cam than I can do on my iSonic 122 with a 7.0 cammed slalom sail!?!
On the other hand the acceleration, pointing, jibing and especially maxed out control of the iSonic is a lot better, so at the end of the day the slalom board would be fastest around a slalom course.
My S-type 115 would beat them both with a few knots on max speed, but loose everything in planing and pointing..
Slalom, speed freeride?? Different boards for different styles but they do overlap a lot as they are basically all high quality and conditions are unpredictable as a design factor.

Good few years ago now Nick Green (a mate of Dave Whites) won a round (perhaps overall ?) of UK speed championship on an F2 Axis. He managed 41 knots on it and was only using twin cam sails !!!
Perhaps its more to do with angle off wind and flat water rather than Slalom or freeride but reckon Slalom would walk it back up course.(ie at angles less than 90 degrees)
Again ,a few years ago a bloke won monthly speed challenge at Sotavento hire centre on an F2 powerglide; his speed was 41 mph. !! (37knots)

|agrelon||I know that on a good day I could make it up to 30 knots on an old AHD 106l freeride board, but at the time I was using a pretty dodgy GPS (garmin etrex) which ended up drowning... despite its IPX7 claims. I think 35knots should be doable on the Futura with my RAM F8. I'll post again on this post my best speeds once I can sail again.|

Certainly Speed boards set records and and ultimately faster are but dont think there`s much difference at all in sheer top speeds of freerides and slaloms.There`s quite a few instances of freerides approaching 40 knots. Martin Van Meurs managed 38knots on a Fanatic Shark which is quite a big freeride to say the least and not renowned for its speed !!
How many so called salalom boards could top out at 38 knots ?????

Havn't had a chance to test out my smaller boards back to back as i only got them at the end of last year and then the wind dissapeared for the winter :-( but a friend of mine has both the I Sonic 86 and W49 speedboard and achieves similar speeds on both boards when the speedcourse is square to the wind (90 to 115 degrees). Once the wind is between 125 to 140 degrees the speedboard is clearly faster.
Like Mark said the I Sonic 86 is a perfect board for speedsailing if you don't want a full on speedboard and it is capable of 40 knots plus. Also if where you sail is choppy then a I Sonic 86 would be faster most of the time because a speedboard needs flat water to get the best out of it and can be slower than a slalom board in chop.
