Posts: 612 Cape Town, South Africa | Wouter, You are quite right that windsurfers will not perform to their maximum in choppy water, I windsurf at the same lake that our speedsailing league is held, and the top guys at speed are unbelievable, when I am backing off and getting airborne, they are locked in and flying. But they are on the right equipment (F2 Missile, Naish Stealth sails), and one of them holds the African record, the other holds the kite world speed record. I see from the SA speed league site http://www.windsurfingafrica.org/GPSSpeedLeague/tabid/834/Default.aspxthat they have 10sec, 100m, 250m records, so not only measured over 2sec, my mistake. At these speeds you will sail 100m in 5sec, I just don`t think you will see a beachcat do that unless it`s on it`s trailer. What the windsurfer guys have to worry about is those pesky kitesurfers getting faster, and faster ... With regard to the tri vs windsurfer video, I`ll agree, no doubt the tri was not making the effort, looking at the water and windsurfer rig size and board choice, it would have been around 18-20knots windspeed, no white horses, very little chop. My guess would be their average speed was around 22-25knots in those conditions, which is consistent to how fast they appear to be going - 40knots looks a whole lot different. And yes, knees make remarkable shock-absorbers, our creator was the first engineer, none have come close to replicating anything that came off his drawing board. | | | Re: Very Large Tri Vs.

can't keep my nose out when the subject goes to sailboards V's Multihulls and speed.
The sailboards don't have to be in a purpose made trench to get high top speeds, recently at Sandy Point a couple 100kms. from where I live, sailboards reached speeds of 45kts. When a low pressure system came in from Bass Strait, mind you winds where gusting 40 to 50 kts. at the time!!!!!!!!!
I have sailed there myself a few times I believe it is one of the best natural speed sailing locations in the world.
But when it comes to sustained speeds in open water nothing can beat a big Multi. The bigger it is the higher the sustained speeds, I have seen speeds of around 30 kts. for miles on the ones I have sailed on.
I have also had the opportunity to line up a few Formula Race boards including the new Olympic board with my F16 they are easy pickings in under 15 kts. With the kite up and a hull out of the water the F16 kills them for speed.

Sandy Point has all the same ingrediants as the trench...... It is very sheltered from waves, very shallow so the chop does not pick right up and gets good breeze from the Southern ocean. It is a natural made speed sailing course and is where Maquarie Inovation is attempting to take back thier record and be the first over the 50 knot mark. Unfortunatly it is a smallish body of water and MI must enter the course at low speed from behind a sand dune and try and hit super high speeds to reach a good average. They have said MI has alread exited the course in excess of 50 knots.... Just got to get a better entry speed. ![[Linked Image]](http://i78.photobucket.com/albums/j91/Tornado_ALIVE/MI_sail_01.jpg) MI with a minor setback..... They reported that they were traveling @ 45 knots early in the run when this happened. It was set to be a record run they believe...... It has now been rebuilt much lighter and stronger. ![[Linked Image]](http://i78.photobucket.com/albums/j91/Tornado_ALIVE/after20-20steb.jpg) Previous record holded Yellow Pages ![[Linked Image]](http://i78.photobucket.com/albums/j91/Tornado_ALIVE/sailing_background.jpg) | | | Re: Very Large Tri Vs.

The current OPEN WATER world speed record is 44.35 knots..... faster than any cat has recorded over an official trial, anywhere. Maxicats have recorded over 44 knots offshore, fully crewed and provisoned. Someone in this forum commented that they might try the outright speed record, if they stripped the boat of everything unnecessary for the short sprint. Also, Orange II is bigger and faster than the maxicat that recorded over 44 (Orange I, probably).

Unregistered | Hi who me,
when did "Alered" beat the Worlds fatest foiling Moth? Please refresh my failing memory and introduce yourself, assuming I was there, I have probably met you.
When speaking to Rohan Veal he has never claimed the foiler Moth has a sailboard type top speed, my recollection was he said about 19kts. The secret to the foiler Moth's speed, is it's average speed around the course, however control is it's problem, when compared to the other craft capable of similar speeds, the Tornado, A class, F18 and F16 don't crash as much, I am afraid I don't have experience with the current racing sailboards around a course to add them to this list.
However I think it would be very unusual for any of them to attain over 20 kts. but in their ideal windspeeds they will travel at around 15 kts. regularly. Each having it's ideal windspeed and wave state, allowing them to excel in the conditions that suit.
In 12-14 kts. of wind "Altered" has been recorded on a Radar Gun at a top speed of 32km/hr, nothing to amazing but the lowest speed was 29km/hr over a series of runs, it is the average speed that is the impressive factor, allowing for exciting performance around a course in anything over 8kts. of wind however Altered's speed peaks at about 15 kts. of wind, this is when the two up cats come in to there own.
I too would love to see F16 one up v's A class, Foiler Moth and Sailboard, around a windward and return course, but fact is they are probably all capable of winning in their ideal conditions.

It is very likely that they ran over more than 500 meters when the speed was recorded. But this is not important. A windsurfer is amazingly fast for its simplicity and price. A monster multihull is expensive and complicated, but more consistent overall. Not much to discuss, really.

It was at the Brass Monkey regatta at the Squaddy; Alerted 35th, Rohan on Amac's boat =52nd (no finishes).
I know you both had gear failure (didn't we all, and yep you do know me....) but from where I was you looked clearly faster in terms of consistent speed. Until Rohan retired in R1, he'd only made up 1 minute in 2 miles on the NS14 and the top Cherubs, you'd come and passed us. Ok, you crashed but so did he, and you were much faster until you both had problems.
R3 was a walkover for the F16s. I think we were all together 1/3 of the way up the beat and by the time I got to the top mark you were well ahead, and he was so far behind his sail numbers couldn't be read.
Of course, it wasn't a great test. The Moth is amazing, as we all know, and the conditions were terrible for it. But the Mothies will talk it up when they beat As and Tornadoes and 49ers, so why can't other people mention it when they get beaten?
Which is not to say that Moths, FWs, As, F16s etc are not stunning machines, I think you're dead right the winner would be the one that had its favoured conditions.
We used to get some FW guys (including one we raced against in raceboards way back when, I think) pacing the KCC fleet at times. In 20 knots or so I'm sure they paced Dave Hart's T and Steve Brewin's A downwind, and they were pretty close to Taipan pace upwind for VMG.
The comment about the FWs and Moths comes from the fact that some FW guys believe that nothing else comes close to them, yet rohan reckons he's as fast upwind, and under 6-8 knots he's much faster all-round.
By the way, re-reading the Brass Monkey thread reminded me that the regatta clearly went to the A Class, with Elvis averaging about 45 knots in Race 1 (check the times...he finished the 6 mile? windward/leeward course in 10 minutes!).
THAT'S fast!!!!!!!!!!! :-)
PS do you get the feeling that any comparisons of all-round speed are getting harder and harder to make these days? Many boats these days seem to have more holes or strong points in their performance than those of 20 years ago. Even when we were racing boards, most of them were more consistent in their performance than an FW board, and shortboards didn't come into it because they couldn't do course races. Even Scow Moths didn't change performance across the wind range like a foiler Moth does, and all fast cats were kiteless.
Just an idea.
