Mark Mills är ju en kille som vet hur man ritar en båt som är sweet. King 40 och Landmark 43 är väl de mest kända just nu. Här har vi Ambush, en 41-fotare som har just gått till Hong Kong (där det verkar samlas en del coola båtar)…
12.50 x 3.65 x 2.60 x 7.050 kg. Ryktet säger $650K = 4M.
Experienced partners Andrew Taylor and Joachim Isler are no strangers to custom boat projects, and when they decided to get serious about IRC performance in Hong Kong they wanted something special. Their new IRC 41′ Ambush has been built by Mark Evans at McConaghy’s chinese operation in Zhuhai, and reflects the brief they originally laid out: it has to be an IRC performer, it has to be aimed at the specific conditions of Hong Kong with an eye towards the far-flung regional events like Kings Cup, and it has to genuinely serve their families as a dual purpose design. With clients like these willing to take a few risks to get an exciting package we proposed a design which combines interesting visual cues with an evolutionary step forwards under the water.
The design effort started with a CFD program with America’s Cup consultants Cape CFD. With the growing maturity of the software and their experience organising and analysing CFD results inspiring confidence in the data, we looked at developing the successful design thread we have been pursuing at this size/weight category under IRC. One area for example to be validated was the shaping of the aft hull sections, some of the results are visible in the increased transom width which can be maintained without sacrificing light airs performance. The two swept-spreader carbon rig is a natural in IRC, while the the medium/light bias of Asian conditions and the desire to sail the boat with less crew the retracting bowsprit option was a perfect fit.
