Speedsailing . Where are we ???
 
With kite having broken 50knots And Sebastien Cattelan claiming 53.37 k with 61.7 Vmax

(see http://www.surfertoday.com/kiteboard...peed-challenge)

Along with Hydroptere now holding record (ratified) at 51.36 with crew claiming 61 knot peaks. (http://www.hydroptere.com/_en/) was wondering what windsurfers were doing about it ??? Anybody getting near 60knots ???

I know my speeds havent gone up at all in 4 years ??? Anything in pipeline Starboard ???

Not much to do: the Kites can sail in absurdly shallow water, while the sailboats have oustanding efficiency compared to both Kites and windsurfers. Which leaves windsurf dead on the water until it can either sail in 2" of water or develop some new revolutionary rig+board that will probably will not look like a windsurfer at all.

By the way: my personal take is that now that sailboats are going 50 knots in open ocean it is pointless to compare with windsurf or kites that sail in canals or ultra-shallow venues. Sailboats seem to be doing the real sailing, while the rest is confined to very artificial conditions.

Color science: "white bottom is lighter and faster"... Or nanoparticle layers that will almost eliminate hull and fin drag.
Davide, this is a good point: at the other end, iceboats are cruising in one mil deep water much faster than any other sailed engine.

Dont think Hydroptere did 50k in what you`d call open sea. Fair enough it wasn`t a canal but it was in a massive harbour.They flipped it in open sea 18 months ago; outer fin (partly resposible for opposing heeling) cant maintain negative lift (down force) in big seas, ie in wave troughs it looses force; boat can (and has ) flipped. For its size it still needs relatively flat water.
(Yes I know outer ama is also full of water; but foil does do its bit)
In rough conditions suspect WS is still fastest ???

In rough conditions.....


- Transatlantic W to E, Ambrose Light – Lizard Point
=> "Banque Populaire 5" 131 ft Tri, Pascal Bidegorry FRA, 3d 15h 25m 48s 32.94 kts
=> 24 H, 908.2nm 37.84 kts
Try to do the same on 500 m

Look at the GPS in open water

And there, they cn drink a cup of tea at 41 Knots

Yes, I can be said that the Hydroptere record was beatten in open water.

So, why windsurfing does not seem able to participate to this record hunt? I see one main reason: money. The record of Antoine Albeau can be improved (it was not make by really ideal conditions: choppy canal, run too downwind a absolute freezing cold) but windsurfers would need a big amount of cash to do so to allow our champions to totally dedicate their time to this hunt - as the kiters do. We need to find the good spot (massive wind everyday) and to built there the good infrastructure and then stick Albeau 6 months there... But who would pay for this?

What an excellent idea !
It should obviously be an Anglo-French effort with Guy Cribb and Antoine.
We will provide a nice windy location like the Falklands.
The French have lots of money so they can pay....
Simple really.

Papounet 15th October 2009 07:21 PM

Thats false !
We have the worst economic systeme off all EU & every one says that UK have the best...

French people are very very poor, but they have the best man for the Job ( not Sarko of course )
English have the best financial place, with a lot of money in traders pockets.

Hi Papounet
Yes I agree those speeds are damned impressive and even more so in conditions encountered but they aren`t the record. Point to remember with Hydroptere is that it easily doubles wind speed; believe on record day it was gusting to 32 knots ;windy but by no means howling . (especially for that region) Its the efficiency of Hydroptere which is trully astounding;resultant of foiling ???

Hydroptere (reputedly) has topped out at 60 knots +; they are now working towards breaking 100km/h barrier. Not sure wether craft you mentioned are foilers but I doubt it.(Dont think the long voyage tri`s are)
Hydroprere(the one built for 500 m and 1000m records) definitely is. Wonder if way forward for us is foiling ??? Wonder what a windsurfer could do if we could emulate this efficiency in ???

Do you really want to make a cup of tea whilst trying to break record ????

There are new rules regarding min depth of water for record attempt.

ďFor every record attempt on a WSSRC approved course, there must be a minimum depth of water, which is defined as follows.
At the time of the run in question, the shallowest part of the course must be covered by water with a depth of at least half the static immersed beam of the craft involved, or 10cm, whichever is the greater. (Guidance note) To define the depth requirement, the craft or board involved should be afloat and the widest part of the hull or hulls touching the water should be measured. In the case of a multihull, the widest hull is measured or hydrofoil if fitted. In the case of an event involving a number of competing craft, the WSSRC Observer can announce at the commencement of the event what the minimum depth requirement will be.Ē

I donít now how they will define the depth requirement for kite since I donít think that kite board floats, at least not with kiteboarder on it.
