New Zealand's richest man Graeme Hart is selling one of his superyachts just a few months after taking delivery of it.

The Kiwi billionaire's 107 metre explorer yacht Ulysses - which only had her first cruise in the Mediterranean in March - is listed by Fraser Yachts in Monaco, with a price tag of $266 million.

Ulysses boasts 15 cabins, a helipad and a jacuzzi. It is staffed by a crew of 42 and can accommodate up to 30 guests. It was available to hire for $400,000 a week.

Businessman Hart recently took delivery of another mega yacht, currently called no.370.

It was designed by Norwegian company Marin Teknikk in cooperation with naval architect Kyle Dick of new Zealand-based Oscar Mike Naval Architects.

The 116m expedition support vessel launched at the Kleven Verft shipyard in Norway three months ago. It gives Hart two ships that are about the size of the Royal New Zealand Navy's two frigates.

Hart's new vessel, designed for long expeditions in rough waters, can accommodate 66 people and is reported to be equipped with a helicopter deck and hangar, plus space for five excursion boats.

Hart, who is new Zealand's wealthiest citizen with a net worth of $9 billion according to the National Business Review's rich list, has a third luxury vessel - the 77m Weta.
