Design
The hydrogen-powered chase boat (HSV) that McConaghy has now begun to manufacture for the AC teams and other customers is in many ways more technically advanced than the AC40s
completed in the yard – and we finish an AC40 every five weeks – these yachts are fully fired up and fully commissioned, sitting in our factory ready to ship out to the teams.’ Evenmore surprising,
however, is that opposite the AC40 production line inMcConaghy’s facility in Zhuhai, China lies an evenmore advanced foilingmachine that is also a spin-off from the Kiwis’ foiling Cup vision: the hydrogen- powered chase boat.
Those who have closely followed the
‘The HSV has to have a range of 75 miles at a speed of 25kts’
development of the Cup over the last year will know that Emirates Team New Zealand launched the prototype and were delighted at how well it worked straight out of the box. This was just as well because under the terms of the Protocol for the 37th America’s Cup, every Cup team has to have
at least one, “hydrogen powered vessel (“HSV”) at the Match Venue to support its on-water race operations”.
Unless the teams want to go down
their own route of development, the New Zealanders’ prototype is the answer and it's easy to see why they might opt for this McConaghy-built machine as the design brief is pretty demanding. Under the terms of the Protocol the
boat needs to be at least 10m long, have a top speed of least 50kts and be capable of cruising under hydrogen fuel cell power alone. The HSV has to be fully on its foils at 24kts and have a range of 75 miles at an average speed of 25kts, which well exceeds two back-to-back AC75 races.
The ETNZ-designed and McConaghy- built AC chase boats are capable of carrying six people including the driver plus 250kg of additional payload, as required by the Cup protocol
