An outstanding creation that provides a remarkable demonstration
of the knowledge and experience of the shipyard and another sign
of the excellence achieved by Alloy Yachts in aesthetics and performance, technology and engineering. It showcases how constant progress in technical innovation can be applied on a fully custom
basis to create a new, exclusive size class of modern yachts. This is another extraordinary result for the New Zealand company Alloy Yachts, led by Tony Hambrook, Managing Director of the company for more than 20 years. Yet again, it is a unique creation and so, once again, a luxury sailing yacht from Alloy Yachts plays the starring role in a detailed portrait in Yacht Première. Two of its sister (although not twin) ships, 51.80 m /170’ in length, have already been featured in the magazine, having been launched in 2008 with naval architecture and exterior design by Dubois Naval Architects. After Red Dragon, a sloop with interior design by Wilmotte & Associates, which featured in issue 9 of Yacht Première, it was the turn of Mondango, a ketch with interior design by Reymond Langton Design that was featured in issues 5 and 12 of Yacht Première. Now it’s the turn of Kokomo, a 58.4 m/191’6” sloop with naval architecture and exterior design by Dubois Naval Architects and interior design by Redman Whiteley Dixon, launched this spring and featured in the current issue of Yacht Première.
This new yacht is the third bearing the name Kokomo built by Alloy Yachts for the same client, over a ten-year period and progressively increasing in size. All three have naval architecture and exterior design by Dubois Naval Architects and interior design by Redman Whiteley Dixon: the first Kokomo, a 40.40 m / 132’6” sloop, was launched in 2000 and later renamed Nuberu Blau. The second Kokomo, a 51.7 m / 191’ 6” sloop – sister but not twin ship to Red Dragon and Mondango – was launched in 2006 and later renamed Konkordia. The new Kokomo is the 20th sailing yacht constructed by Alloy Yachts to a design by the well-known expert Ed Dubois. It also the 26th sailing yacht built by Alloy Yachts, and notably the sixth of more than 50 metres in length, but most importantly it is the first to cross the 55 metre threshold. It’s a constant, unstoppable ascent for Alloy Yachts.
The main dimensional and technical data
With numerical construction code AY39 and naval architecture by Dubois Naval Architects, the new Kokomo has been constructed using light aluminium alloy for both the hull and the superstructure. The construction is compliant with the classification rules of Lloyd’s Register of Shipping (LRoS) and the Maltese Cross 100A1 SSC YACHT MONO G6 MACH UMS; it also meets the requirements of the Maritime and Coastguard Agency (MCA) for a Large Commercial Yacht Code LY2.
In terms of hull dimensions, the Kokomo’s length overall is 58.40 metres, equivalent to 191 feet 6 inches, with an SWL of 53.64 metres, equivalent to 176 feet 0 inches and an LWL of 52.12 metres, equivalent to 171 feet 0 inches; the maximum beam is 10.90 metres, equivalent to 35 feet 9 inches. The maximum draft is variable thanks to the lifting keel, which has a large vertical travel of 3.20 metres, equivalent to 10 feet 6 inches: with the keel fully raised, minimum draft is 4.90 metres, i.e. 16 feet 1 inch, while with the keel fully lowered, maximum draft is 8.10 metres, i.e. 26 feet 7 inches. The new Kokomo has a gross tonnage of 495 GT and a load displacement of 598 tons, equivalent to more than 1,320,000 pounds.
The keel ballast has an overall weight of 120 tons, equivalent to 264,900 pounds, consisting of the sum of the steel fin weight – 30 tons, equivalent to 66,225 pounds – and the weight of the bulb, a steel casing filled with lead, which is 90 tons, equivalent to 198,675 pounds. The new Kokomo has sloop-type rigging, typified by the mast with five levels of quartered spreaders: the mast height above the waterline is 74.30 metres, equivalent to 243 feet 9 inches, while the mast height above the deck is 72.36 metres, equivalent to 237 feet 5 inches; the carbon fibre mast tube weight is 6.5 tons, equivalent to 14,350 pounds. The mast and boom were produced by Southern Spars in carbon composite with graded high modulus carbon fibre; the new Kokomo’s mast is also equipped with composite carbon-aramid rigging, called EC6+ Continuous Carbon Rigging, from Southern Spars, complete with high-strength stainless steel Nitronic 50 rod rigging parts from Ocean Yacht Systems (OYS).
