Simon van Velthooven calls himself an "enthusiastic weekend warrior" these days as he continues his transformation from Olympic cyclist to bona fide sailor.
The 29-year-old former Olympic track cycling medallist became an integral member of Emirates Team New Zealand's success at last year's America's Cup when they utilised cyclors. He could normally be found at the front of the high-speed AC50, head down, relentlessly turning his pedals to feed the hydraulics for the speed machine.
Grinders will replace cyclors for the next America's Cup in 2021 but van Velthooven is eager to earn a spot on the boat for his sailing skills.
His development will take another step next week when he climbs on the 52-footer Kia Kaha for the Bay of Islands Sailing Week, which is the country's biggest keelboat regatta.
He will join Team New Zealand chase boat driver and Kia Kaha skipper Chris Hornell, who has enjoyed success at Bay Week before.
