PURPOSE is built for the far side of the map. This 55 m (180 ft) Trinity Yachts explorer, launched in 2005 and completely refitted in 2023, carries fuel for around 5,000 nautical miles, so a week aboard can follow the reefs of Melanesia, the Great Barrier Reef or the coast of New Zealand rather than a marina timetable. Twelve guests share six suites styled by Dee Robinson, two of them full-beam, looked after by a crew of 14 that includes a dive master and two massage therapists.
Up on deck there is a Jacuzzi, a sundeck that becomes an open-air cinema after dark, and room for long shaded lunches. Being RYA-approved as a water sports centre, she suits families and first-timers as much as keen divers, with e-foils, jet skis, Seabobs, kite-surfing kit, a giant slide and a 9.75 m Intrepid chase tender all carried aboard. For a South Pacific superyacht charter with true expedition range, PURPOSE stands apart.
