Posts: 1,669 Melbourne, Australia | Check out the video here - http://www.hydroptere.com/index.php4?lang=EN L'HYDROPTERE HAS EXCEEDED THE 45 KNOT BARRIER Faster, Higher, Further... Samedi 20 janvier 2007 Today, l’Hydroptère reached the record speed of 46.5 knots and, according to our measurement system, she beat the 500 meter distance record in her category as well as the absolute record for the nautical mile. After a few training sessions spent on the adjustment of the boat, l'Hydroptère has now entered a new phase of "Performance" from the beginning of January. The crew is now increasing the number of training sessions to define the best conditions and boat configuration to enable her to reach her first objective. The first two records Alain Thébault and his crew would like to beat is the 500 meter record, held by Techniques Avancées with 42.12 knots and the Nautical mile record, held by Finian Maynard with 39.97 knots. Today, during a training session, our measuring system recorded a run at 43.05 knots on 500 meters and 41.74 on one nautical mile which prove the reliability and potential of l'Hydroptère in the 5th version. The completed improvements on the structure over the last nine months in the shipyard, plus the optimizations carried out since her launch, have made it possible to have a prototype technologically accomplished, with an incredible speed potential. The speed peak recorded at 46.5 knots proves that the boat and her crew are ready to take up the challenge as soon as possible i.e. the absolute sailing speed record set at 48.7 knots on 500 meters. Everything is being done to accelerate the certification of the speed reached before Port Haliguen, in Quiberon Bay, in order to make those first speed breaking records official for l’Hydroptère. | | | Re: L'HYDROPTERE HAS EXCEEDED THE 45 KNOT BARRIER

Ultra Cool boat no doubt, I love seeing the envelope pushed like this... but I would have to say the sailboard has it beat hands down when it comes to accessibility and bang for your buck.
Regards, Bob Agreed, but the kit will be more than $5000. Speaking to my local chandler (and windsurfer) and a top of the range carbon mast is £1000 - that is quite a lot of the $5000 gone !

Posts: 1,152 tampa, fl | I would like to see speed sailing take a somewhat different approach. Right now, the record is held by a windsurfer that used an asymetrical rig. The luff sleeve is much longer on the windward side than on the leeward side, there is no boom on the leeward side, and an additional strut that connects the leech and luff ends of the boom to provide additional stiffness. That all makes this windsurfer capable of sailing in only one direction. Yellow Pages and the similar boat (not sure of the name) also are asymentrical craft. To me, a true sailing record should be held by a craft that can complete the run on either tack. I believe Hydroptere can do this but I may be wrong. Thoughts?

Posts: 9,582 North-West Europe | You mean to say that the sailboard used to set the record only costed 5000 to develop from the sailing "barn doors" that were introduced 30 years ago ? That is like saying it only costed 30 bucks to have the DVD player developped. but I would have to say the sailboard has it beat hands down when it comes to accessibility and bang for your buck.
In response I would say that actually landyachts and iceyacht have gotten this particular game down. Remember the Blokart. These things clocked a max speed of 95 km/h (51.3 knots) already without the need for a special ditch. Come to think of it, was digging this ditch included in the 5000 quote you gave ? And there isn't greater accessibility then driving a 2100 Euro Blokart on a nearby carpark. You don't even have the car top it as it folds into a small package that fits inside your boot. Landyachting ultimate record is 188 km/h I believe (101.6 knots) Wouter

It would be relatively simple to disassemble the windward vaka/ama to reduce weight and drag. Will they do that to try the absolute record?

Posts: 6,049 Sebring, Florida. | The Wright Brothers figured it out over 100 years ago, if you want to go fast, get out of the water!
So at what point is a "Flying Boat" not a boat? Maybe they should design the aka's (the beams) more like large wings, with the foils at the ends, and generate some lift like an airplane. If they design them right, 49 knots is plenty of wind to generate a useable amount of lift.
And on the whole speed sailing records thing, I think they need to continue to do the runs in the Ditch to develop what is fast. Then they need to figure out how to apply it to a real boat that will operate in the real ocean. That Tri is out in the real ocean, or just slightly above it! Too bad there wasn't a fast windsurfer next to him for comparison!

Posts: 9,582 North-West Europe | Jake got this absolutely right ! The most stunning thing about Hydroptere is that this boat is raking up the speeds in open water. All the windsurfer and even Innovation explorer records are done in perfectly flat water only a few meters aways from a dry sandbar, the coast or in a specially dug ditch. Hydroptere does it amids a rought seastate. As such Hydroptere is something really really special. Wouldn't it be fun if they crossed the 50 knots barrier first and none of the special craft in very special ditches (c.q. locations) Hell Hydroptere could theoretically cross the atlantic this way ! And that is not me just saying that, here , they announce the plan to build a version that will sail around the world. Wouter

Posts: 9,582 North-West Europe | "All the windsurfer and even Innovation explorer records are done in perfectly flat water only a few meters aways from a dry sandbar, the coast or in a specially dug ditch." that may be true of the new records...but windsurfers hit 40+ mph regularly in rough water...it might not be 45 knotts ...but still 40 mph in a wicked 3-4' chop on top of a good ground swell is still moving really fast on the water.
Right, the trouble only is proving it. Over the period, both the wind surfer and kite boarder lost a bed against an olympic tornado held at the German boatshow. At the the deli petit navire we have more then enough photo evidence that windsurfer and kite boarders are not that fast after all. Look at : http://www.youtube.com/watch?v=FWINygISxDE&mode=related&search=(and you really should look at this video) For two seasons now I know personally that kite boards can't perform in the conditions I'm out with my cat (up to 25 knots) despite using the biggest kite sizes. And I'm no where near 40 mph. Pretty much to only reall impressive speed data we have of both kite and windsurfer comes from the French Ditch, walvisbaai and several stretches along a dyke or the Danish sandbars where the water is only 3 feet and perfectly flat. I guess alot of people just assume that they reach these same speeds when they are going 50 % airtime over the large swell at their local pond, but they are mostly not. I thought you guys would be much more tuned into windsurfing in europe than we are here in the US...but either you live where the windsurfing sailing talent is on the less extreme side of things or maybe it just never interested you to the point of really paying a lot of attention to it.
None of the above is the case. But it is too much to detail at this time. Usually when the conditions are really good for high performance windsurfing no ones on the beach because they don't like getting sand blasted...Tell Dunkerbeck you can't go fast on rough water...
"Usually when the conditions are really good for high performance windsurfing" Exactly my point ! These things need very special conditions to perform up to the 40+ knots range. And please lets not trouble the water by coming back with 40 MPH claims. We are talking knots here and not miles per hour or 40 km per hour. It is 40+ knots or you are simply not in the game. but still 40 mph in a wicked 3-4' chop on top of a good ground swell is still moving really fast on the water.
Hydroptere (in the video on its webpage) is sailing in something more then "wicked 3-5 chop" and it is also a little faster then 40 mph (= 35.6 knots). Sorry mate, windsurfers are fast craft but hydroptere does something really exceptional here. Wouter

I agree Wouter...it is exceptional...but the chance of my experiencing it personally is remote, while windsurfing is accessible to anyone who has a few thousand dollars, is in good physical condition and is committed to gaining the expertise. I guarantee you that in the extreme conditions that we look forward to sailing in, there is no catamarans to be found…when you can bairly carry a 3.0 meter sail down to the beach … a catamaran is not even going to be able to sit upright on the beach, let alone sailing out on the water.

Posts: 902 Norman,OK | Yeah, being able to sail in extreme conditions is great but those are rare. Look at average conditions.... winds of 7-15. Not many windsurfers out in that because it isn't fun but cats are everywhere.
In reality you can sail a beach cat up to winds of 35mph without having to do anything special. I don't even have to change sails between winds of 10 and 35 when the windsurfers will have gone through 2.
Also what can you do on a wind surfing board, jump a few times, then get tired and go in. On a cat you can pack a lunch,take out the g/f, fly a hull all the way to the beach have a nice meal and then go blast around some more. Can you take anyone out with you on the board?
I am not saying that boards are not badass and I know that they could smoke me speed whys....but they can't do alot of stuff that cats can.
