The amazing looking Speedboat is surely destined to break a few records. Spar makers Southern Spars describe the thinking behind the rig
In blustery weather, the new Juan Kouyoumdjian-designed 100ft maxi, Speedboat, was launched in Auckland’s Viaduct Basin. It’s a yacht designed to produce blistering speeds and the first record to fall could be the Newport Bermuda race time this June.
Built by Mick Cookson in Auckland this yacht looks fast standing still, her radical underwater features and amazingly flat run aft pointing to a boat that’s going to need a lot of handling but could produce startling speeds off the breeze.
It goes without saying that her rig is the ultimate collaboration of latest design thinking and innovation in rig technology.
The 44.3 metre high deck-stepped mast was designed and built by Southern Spars. It is the tallest and most powerful maxi rig produced by the Southern Spars yet, meaning it has the highest righting moment of the maxi rigs produced.
Speedboat’s 5 spreader cathedral in-line rig is built from high modulus carbon fibre and is equipped with a complete set of EC6 carbon rigging – the same rigging product used on Open 60 yacht Paprec-Virbac, winner of the Barcelona World Race.
One of the most noticeable features on Speedboat’s rig is th aerodynamic structure. The rig uses EC6 carbon continuous rigging with internal tangs. This means the entire rigging runs free from the deck to inside the mast without any bulky external fittings or attachments. Because there are no bulky end fittings on spreaders, the spreader ends are considerably smaller, making for a cleaner, lower drag spreader end. The runners are also made from EC6.
The internal halyard locks will have some of the biggest loads seen on a racing yacht, with the halyard lock for the Code Zero sail having a 20 tonne safe working load.
Speedboat is the first maxi to have a deck-stepped rig produced by Southern Spars. Steve Wilson, rig designer for the project comments, ‘The decision to go with a deck-stepped rig was based on structural reasons. It’s also easier to pass the loads through a bulkhead rather than through a mast and it means no water comes down into the cabin.’
SpeedBoat is due out on her maiden sail today 17th April, when sea trials will commence.
All eyes will be watching her first race in June 2008, the classic Newport to Bermuda race, which will include a very competitive line-up of Southern Spar rigged yachts, including Rosebud, (IRC winner of 2007 Sydney to Hobart), Numbers, (IRC winner Div 1 Key West) and Rambler, (winner Rolex Middle Sea race).
