Olive was launched in Heusden, in the Netherlands on May 7, on what would have been Henry's mother's 88th birthday.
The boat is in every way a tribute to her: "the Olive Suite" features olive-coloured furnishings and a dome of olive glass that contains her ashes.
Henry plans to sail the world, aiming to be back in New Zealand for the America's cup in 2021.
He told the New Zealand's Woman's Weekly he feels like his mother is "on the journey with me" and hearing the words "Olive, Olive, Olive" come across the radio when he comes into port helps keep her alive.
Henry is enjoying the anonymity his new life offers him. Far from the headlines of New Zealand news, he's free to be himself.
"I loved what I did when I did it, but I certainly never craved the audience," he says.
