World Sailing Speed record broken!

September 6th, 2009 No comments

It’s a development we have anticipated for some time – the large multihulls taking the speed record from the kitesurfers and specialist (often one-tack-only) machines such as Yellow Pages and Macquarie Innovations.

Now the team on L’Hyroptere have done it – setting a new record of 51.36 knots over a 500m course with a peak 55.5 knots (thats over 102 Km/h or around 64Mph!).  Designed with this purpose in mind, Hydroptere is a specialist speed sailing trimaran with advanced floats modelled on a sea-plane float and foils that allow the entire yacht to sail 100% out of the water when the speed is sufficient.

55 Knots!

55 Knots!

And it was today – sailing at 55 Knots in only 28 knots of wind.  Those of you wondering how this is possible – think of a car travelling at 20mph in no wind.  The wind felt out of the window (the Apparent Wind) would be 20 mph in your face.  Much the same effect happens with this high performance sailing.  A yacht that is efficient at converting wind energy into speed effectively makes its own wind.  So the wind over the deck on the trimaran would be about 28 Knots + the effect of the boat’s speed.  Given that the boat would have been tight reaching, the 55 Knots of boat speed would probably translate into an additional 20 Knots over the deck – so she was sailing in about 40-50 knots of breeze!

Yes! 55 Knots!

Yes! 55 Knots!

What’s next?  Will the BMW or Alinghi boats beat this?  Possible – in lighter air.  It boils down to issues of sea state.  When the wind is blowing north of 20 knots the sea gets lumpy.  While the foils help with this, as does a carefully chosen racetrack (the Trench for kitesurfing records or sheltered bays for the other attempts), ultimately the speed records will be held by the most efficient boat, since the higher speeds can come in less wind which means lower sea state.  Both the Alinghi and Oracle boats are super efficient.  And dont believe they dont have some trick with foils that we haven’t seen yet!

I think there is way more to come in this arena.

55 Knots - what's next?

Alinghi 5 Damaged!

September 2nd, 2009 No comments

Our favourite catamara in the whole wide world broken????

From the Guardian:

Alinghi 5, the catamaran built by Ernesto Bertarelli for Switzerland’s defence of the America’s Cup, is reported to have suffered a major structural failure while testing in light winds on the Mediterranean. The 120ft high-tech craft, flown over the Alps by helicopter from Geneva to Genoa, is reputed to have cost in excess of £20m to design and build.

Observers of the testing claim that the carbon-fibre structural beam that runs from the centre of the main crossbeam at the mast to the aft cross beam close to the starboard hull, was fractured in the incident, which occurred in nine knots and a flat sea. The sails were dropped and the catamaran towed slowly back to its base, where the mast was removed immediately.

A video of Alinghi 5’s arrival by air undeniably shows the starboard aft ‘corner’ going into the water and the boat twisting on it. This could have been the root cause of the damage to the catamaran.

Alinghi sources say that for the past week the team have been doing nothing more than “ongoing work and routine maintenance” and that this was afforded by “a suitable weather window for carrying out this work.”

The video is here :

Another cool video from Alinghi on their Monster Cat

Another cool video from the folks at Alinghi. This grudge match is setting itself up to be an awesome sailing contest!  Pretty sure Larry Ellison will launch another boat now with engine powered ballast and controls – and probably lean towards lighter air as well (it is clear that this Alinghi boat will crash and burn in the heavy stuff!.

I would guess he will wait until the definitive venue announcement that is in the next few weeks – super important for the boat design.  Keep watching this space for the latest!

Check out the video here.

Can’t Resist posting more piccies of the Monster Multihull

July 23rd, 2009 No comments

This thing leaves me gobsmacked!  Here are a few more shots of the Monster Multihull – also plse look at the video it is totally awesome.

Awesome

Moere Awesome - look how little wind there is

And on a slightly more technical note, check out the mainsheet.  Where in the old days one would see ropes and blocks we now see two rams attached to that V8 snowmobile engine.

Use of hydralic rams instead of ropes and winches on the main sheet.

And over she goes!  Well – it kinda makes you wonder how robust this all is.  How do you dump the mainsheet when its a ram?  What happens in a puff?

Alinghi 5 – the Monster Cat sails!

Awesome!

Awesome!

Well – it didn’t fall apart.  Yet.

Still a fair amount of controversy over that engine (which I have heard is from a snowmobile).  Apparently it runs (noisily) all the time and supplies power to the winches.  Observant observers will notice the lack of winch pedestals (the handles to wind the winches found on normal big boats).  How they will get away with this under the rules is still to be disclosed.  As defenders of the cup they are able to change the rules, but since they already announced that the match will be to ISAF rules they will have to be amended for this.  There is some precedent – the really large monohulls also use hydraulic power for winches.

Look closely at the hulls - those specs are grown men!  Gives you and idea of the scale.

More Monster Multihull Madness

Had to just bring a few more pics of this Multihill Mania that is developing in the world of the America’s Cup.  From the BMW Oracle sea trials …

From the Swiss camp as they prepare to try their creation out today, a few more pics …

War of the Monster Multihulls

July 9th, 2009 No comments

It is hotting up in the “spend and ignore the recession” America’s Cup multihull build race.  BMW Oracle have launched a new version of their 90 foot trimaran, and so far have not lodged the customs house papers so they can still change it further.

Its hard to get an idea of just how big this beast is from that photo.  The little glitches at the end of the boom are people! Take a look at the following pic for a better idea as to the scale …

While all that goes on the Swiss are progressin as well, emplying the services of the biggest and most powerful helicopter in the world – the Mil Mi-26 – to carry the hull in to Lake Geneva.

The Swiss are opting for a Cat instead of a Tri which would be faster particularly in light air, but poses significant build and design challenges (there is an issue with a huge mast pushing down on an area where there is no boat – in the middle).

There is also a bit of a mystery surrounding a huge V8 mounted on the back beam.  I presume it is related to hydraulics – there are numerous tubes leading away from it. Not sure how all that works under the rules!

Alinghi unveil their monster

July 6th, 2009 No comments

Alinghi unveiled their base defender on the weekend.  I say base because they may modify it extensively before it is final.  For one thing the current soft sail configuration may be changed to a solid rig although I think that is unlikely given the engineering challenges involved.  From the Alinghi website ….

Alinghi, the Defender of the 33rd America’s Cup, unveiled its 90ft catamaran this weekend in Villeneuve, Switzerland. This multihull represents a culmination of Swiss multihull heritage and is the first step in Alinghi’s development process towards the 33rd America’s Cup in February 2010. The boat will be launched by helicopter next week on Lake Geneva before the process of ‘debugging’ begins and the boat goes sailing for the first time. “
