Alila Purnama, Indonesia
This 46-metre mahogany vessel was built to resemble a traditional Indonesian phinisi sailing ship. The boat rises through three decks, with custom-made furniture in five cabins, a Padi-certified dive centre and several spaces for alfresco dining. Tailor-made charters around Indonesia are available year-round, but she also sails on set itineraries to wildlife-rich Komodo Island, the volcanic fleck of Ambon and the exotic chain of Raja Ampat in West Papua province.
