2013 SIDNEY-HOBART RACE

The 100-footers in the 2013 
Sydney-Hobart Race 
A Battle of Giants


Wild Oats XI, 2013 profile


Launched three weeks before the 2005 edition of the Sydney to Hobart race, Wild Oats XI proved an immediate success. Since then, she has hoarded silverware to the point of appearing to be invincible (six Sydney-Hobart line honours wins, including two trebles for winning on handicap and setting a new record).

Though her appendages had been revised continuously, the yacht was still prone to nose diving when running in seaway, thus limiting her speed potential. A solution licensed from Dynamic Stability Systems was developed and tested during the 2013 Hamilton Island Race Week: It consists of a lateral retractable horizontal foil, located just below the waterline and alongside the mast.

The thick carbonfiber foil measures 55cm along the chord and extends 275cm outside the hull. It generates vertical lift to the forward part of the yacht, thud providing better planing ability.

The forward centerboard, with a thick profile, was added in 2012 to stabilise the yacht and avoid windward and leeward broaches when reaching the crest of waves in downwind sailing. Wild Oats XI's light displacement and her long waterline and bowsprit allows the centre of effort of sails to move forward significantly; The forward centerboard prevents a lee helm in these conditions.

Wild Oats XI, 2012 profile


Between 2007 and 2008, Wild Oats XI was fitted with daggerboards amidships, positioned forward of the mast, with a 10° slope, thus correcting the yacht's tendency to sail on her topsides when heeling.

Wild Oats XI, 2005 profile

Wild Oats XI was launched in 2005 as a development of the 60ft Wild Oats IX (2002) and the 66ft Wild Oats X (2004), all penned by the same designers Reichel/Pugh with CBTF appendage configuration including a canting keel, an aft rudder and a canard rudder forward of the mast.


Perpetual Loyal, 2013 profile

Perpetual Loyal, lines


The lines of Perpetual Loyal were developed from the trends in the IMOCA Open 60 and the Volvo Open 70 circuit. Scaled to 100 feet, the lines are so sleek that is very difficult to read the shape of the yacht in her aftersections. Because of this, her horizontal sections (which are parallel to the waterline) all stop abruptly at the transom. Half the yacht's weight is located in the canting keel which may be swung to windward under sail. In a breeze, 8 cubic metres of liquid may be pumped to her ballast, allowing for a huge righting moment that her opponents cannot match. Furthermore, Loyal's ability to plane offwind give her exceptional top speed. During the SOLAS Big Boat warmup challenge ahead of the Sydney-Hobart race, she was taken over by Wild Oats XI after her spinnaker blew out, a reminder that victory can only be achieved if nothing fails.


Wild Thing, ex-Skandia, 2013 profile    

Ordered by Grant Wharington en 2003, Skandia won lines honours in her inaugural Sydney-Hobart race. In the 2004 edition of the race, she retired after losing her keel whilst she was heading the fleet. Her canting keel received several modifications thereafter: Originally 4.80m, her draught increased to 5.20m in 2005, 5.50m in 2006, and finally a staggering 6.80m in 2009, which is a record for an IRC maxi. The hull was also entirely remodelled in the rear third of the yacht's length, giving the yacht sleeker and fuller lines.

Grant Wharington had hoped that the dark livery of his yacht, now called Wild Thing, would have distinguished her from the rest of the fleet, but Perpetual Loyal's new black coat and 7 metre beam could cast a very long shadow...
