Kiteboard speed record

Shoot the breeze and stay in the loop with the unhinged and unhooked word on the street.

So I hear a french bloke took it back from the yanks , 56.62 knots (65.15 mph) / 500 mts.

Need to squeeze another 10mph out and take the sailing speed record back from the yatchies :-D

There's time for this record to change hands again a few times, Alex and Rob are going to be there for a good few weeks yet and the location has to be even better than the Luderitz strip so well capable of producing record breaking speeds. Another 10 knots is a big ask but you have to remember the millions that have been pumped into the Vestas sail rocket compared to a bloke on a kite and a plank of ply, I reckon you get more for your money knot to knot on a kite.

judging by the video, the board are riding REALLY nose high...

Is that normal.

I have acquired a couple of speed boards but I am riding them a lot flatter...

Gaz, do you have thoughts on this?

I'm 3 years in and still learning T, all I can say is that the more power you are dealing with the heavier you will need to be on your back foot hence probably the reason Alex is nose high. That said once he bears away the board will flatten off, BUT if you flatten off too much before bearing well away you will be prone to sliding out, it's a very delicate line because you want to hold loads of power but not too hard on the edge to be stalling speed. If you join sportstracklive.com you will be able to see GPS tracks and it's a good way to see that as the tracks bear away the speed increases, I think a lot of the speed photos you see show the rider loading up before bearing away. All that said every speed rider has a different board, stance and technique so although you can get a general idea from footage of others you need to develop into what suits you.

Any idea on the gear he's on? There's no logos on the kite or bar as far as I can see. A small Fone sticker on the board though.

I don't understand. At the end of the video it say's New kite speed record, but that can't be right. Do they mean new speed sailing record ?

I have just been told today in conversation from a very good source that Alex has in the region of 12+ prototype kites from Fone who are his sponsors as well as VW, he is one of very few properly sponsored riders in the world, this is probably the reason for no logos. I would think at the end of this Salt and speed event there will be an official press release that will include more accurate information of the kit. One thing worth mentioning is that most speed riders are on one off and usually home made speed boards, I can only think of 2 companies that have produced a speed specific board as it is a very minority discipline within a large sport.

[quote] nose high [/quote]
I think they are keeping the minimum amount of board in the water for speed and control.
Once able to get to speed, power is available, you want minimum drag, and minimum lift.
Too much of either and the board feels too big, you lose control, and crash.
For me this happens at about half the speed these guys ride!
That overpowered on a light wind board feeling....
Nearly all the drag on what is almost a tiny flat plate of a speed board is skin friction, so less skin in water = less drag.
And at that speed, only a tiny bit of board can be in if the rider is to be able to trim the board and stay in control. And to get that force out of a small area, AOA can be large, therefore sometimes nose high, tearing a hole in the water... that's how it looks to me.
But I have never really sailed much over 30 knots, I think.
Certainly confident I've never seen 35. So what do I know?

Your completely correct that the smaller the surface area the faster you need to be going before it creates sufficient lift to plane smoothly, in addition you need more power to actually get the board lifting and stable.

I built some boards for speed week with very large cut aways underneath that need much more power to get moving and we're unbalanced until they were moving at 30kts then they just stabilised and tracked through anything.

They ride very nose high, great on chop and had very high back leg pressure but it worked as a principle, the next boards are going to be a tough wider, slightly less rocker and frontal area and a small cut out to get better and smoother acceleration.

The boards Alex uses I have no idea how they work with the extra section at the back on the toeside, might have to do a bit of digging to see what it's all about

As James says, you need to be going pretty quick before the boards start to actually work.

I have been using an xcellerator board at my local flat spot and at first I was really struggling to get it really going, I thought I was just too heavy for the board but once you are juiced enough the board just goes! at about 30 knots your heel still catches the water and it is quite painful. You need to push though that, get your weight super low and pull that bar in! over 40 and it starts to really make sense, the board feels like it is running on tracks, it's serious point and shoot sailing. At 44 the world is going past so fast that it is hard to fathom what is going on and my biggest struggle for a long time was how to slow down. You cannot put your hand in the water at that speed, you will hurt yourself, as for using your ass to slow down, same rules apply. Don't put your ass in the water at anything over 35 knots, it's like getting a hundred hand slap from E Honda.

I have yet to have a really bad slap at serious speed, I seem to come unstuck at lower speeds as the board hasn't settled yet.

Seriously, if you have a flat water spot near you and some time and money, get a speed board or build one. There is a chap in Germany called Tillman who rides homemade boards (wood) and has peaked at over 60 knots. You don't need something that high tech to get really good speeds. The only thing I would really recommend is a good, well fitting helmet as the board will often be launched into the air on impact and they are not head friendly.

This Aguera speed board looks more of a simple shape. Damien Leroy has a max of 51.99 knots on it.

Maybe that's why it's slower than Alex's board? :wink:
