Dunia Baru

Translate her name from Indonesian and you get 'new world', a fair promise for what a week aboard shows you. She is a phinisi, the traditional Indonesian sailing ship, built by hand from teak and ironwood by Konjo boatbuilders in Ara. Below decks, the people responsible for the Aman hotel group's own yacht updated the rooms, which is why they feel calm and crafted rather than rustic.

What really sets her apart is how a week is run. A cruise director on board plans the route around what the group wants to see, and the crew have spent their careers in these waters, so the quiet bays, the villages and the best reefs are familiar ground to them. In Komodo that might mean a walk ashore to see the dragons; in Raja Ampat, days built around reefs that hold some of the richest marine life anywhere.

Diving is the core of the programme. Fourteen complete scuba kits live aboard alongside specialist dive staff, and anyone new to it can earn a PADI qualification before the week is out, so seasoned divers and first-timers in one family each get their day. The owner's commitment goes beyond the yacht: no single-use plastics or reef-damaging products are used on board, scientists from the University of Papua have used her as a base for research into Raja Ampat's black coral, and guests can visit an eco learning centre the owner built in the village of Sauwandarek.

One practical point: some agents present her rate as inclusive of meals, house drinks, diving and national park fees, while other listings quote the rate plus expenses, so it is worth confirming exactly what the contract covers.

She suits curious families and groups of friends, divers above all, who want culture, wildlife and reefs more than speed. Travelling with a baby is easier than usual, since one cabin has a cot made to fit. Skip her if the plan is to rack up miles quickly, or if you expect the gym, beach club and nightlife of a Mediterranean superyacht.
