Wow, 50 knot top speed in 17 knots of wind! That's an efficient craft-must be all the hot air from the MacBankWankers.....

I love the way the describe it as a sailing boat, when it can only sail one way, WTF?

This is a much better video, and record!

There's a lot of yacht sailors that would argue that kiting isn't sailing.

of course it`s sailing.[what else would it be] you edge to go up wind like any other sailing craft you have a sail albeit 30m away but so what and you have a board[so does a wind surfer] get over it we win.

yes and no really. The arguement is that we are doing it a smooth surface. Basically riding on a frictionless surface just above the water. Sailing boats are forced to ride out the chop and all the bumps, which puts them at a big disadvantage. It is unfair to put the two agains each other. We do beat poleys hands down now though[}:)]

from that article "sailboarding fraternity continuing to push the limits down the one kilometre long man-made French Trench at Saintes Maries de la Mer"

if that is considered legal then kiting on the shallowest water should be too, that channel would never get a ripple....

Really boats could have a stupidly big kite attached to them as well which would let them ride the same way as us, im pretty sure we ride through the water in exaactly the same way it's just thaat we dont have as much weight to displace as much water so it looks tlike we are "skimming" ontop.

You and I both know the argument is flawed and is really based on feeling threatened by the quickly evolving sport of kitesurfing.
The yachty speed records are set is super flat water, too.
By boats that can only sail one way, they are the joke and everyone can see it except the spoiled old brats who are whining.
We displace water, and are not skimming on top of the water.
We are sailing, with a remotely controlled sail, commonly called a kite.

In my opinion, sailing is the act of moving over the surface of the water using a craft that generates a mix of hydrostatic & hydrodynamic lift whilst powered only by the wind. Once you lose contact with the water for an extended period you are flying/gliding.

Kiteboards generate a tiny amount of buoyant/hydrostatic lift (approx 1kg) with the rest (90%) coming from hydrodynamic lift. An 18ft skiff will be about 75% hydrodynamic lift and a maxi yacht (Wild Oats) about 25% hydrodynamic lift at full speed. All boats are 100% buoyant lift at rest.

The drag on a kiteboard will be almost completely frictional due to the water passing over the board surface and the spray produced. The wave drag will be quite small due to the high speed-to-board-length ratio.

While the authorities have begrudgingly accepted kites into the sailing fraternity, I understand their hesitation in doing so. The WSSR Council have ratified the kite speed record.

Most sailcraft are vessels with attached wind powered device (sail) piloted by one or many humans. Kites are a little different where there is no vessel and the sail is attached to the pilot.

Why are we bagging the sailing community? Their history is long and proud. Are we not also a little slow to accept different forms of our chosen sport? Do we not ridicule those who choose alternate methods of kitesurfing? (inflatables hate foils, c's hate bows, bow's hate c's, everyone hates Flysurfers)

I reckon the speed sailing records should have divisions to differentiate the different forms of sailing.

Already been tried, didn't have the desired effect

haha, yeah but where would the fun in that be! Le Hydropter (spelling) is pretty cool though, it's a 60' tri on hydro foils (and they don't sial it on perfectly flat water) and they can sail on both tacks. They where going pretty well at the speed record till they pitch poled doing 40 knots . I think the boats that where built for the DoG challenge could have a good go at itas well, apperently the Oracle boat is using it's "small" mast (god know's how big the big one is).

There's about 12 or 13 different Classes for the 500m speed record 3 of which being female classes. Though I don't know what the differences between some of them are!

Kiteboards are in fact a vessel, just much smaller. The underlying physics is still the same regardless of vessel size or whether the kite is attached to a mast or person.
