Si Datu Bua (meaning “Beloved Princess”) was handcrafted with Indonesian heritage. She is the smaller sister of Silolona and just as luxurious.

Built by the legendary Konjo Boat Builders of Sulawesi, Si Datu Bua was created from carefully selected materials that call to mind the classic phinisi spirit. Reflecting the phinisi ships that historically traded along the spice routes in the region, Si Datu Bua embodies the essence of Indonesia’s past with the contemporary luxuries expected of a modern-day superyacht.

Si Datu Bua is a wonderful choice for families or groups of friends looking to sail in authentic style, and her crew of 12 includes an expedition leader, chef and dive instructor. Her team is known for an in-depth knowledge of the culture and customs of Indonesia.

Onboard Experience

Si Datu Bua has three classically decorated, romantic guest cabins located below deck.

Adorned with traditional woven textiles and Indonesian artefacts, these suites combine the warmth of solid wood with neutral cream tones, creating an elegant, relaxed ambiance.

All suites feature air-conditioning, king-size beds and en-suite bathrooms.



An indoor lounge and dining area is naturally lit with large windows, carrying through the theme of wood combined with cream linens and printed textiles. Outside, there’s a beautifully lit lounge area with daybeds, sun loungers and ample space for alfresco meals at the dining table.

An additional lounge on the aft deck provides space for relaxing in the shade and taking a moment to appreciate the exquisite landscapes that Indonesia has to offer.

The dedicated chef prepares menus according to guests’ preferences, with culinary creations including traditional South East Asian specialties as well as classic Western fare. Onboard, Si Datu Bua is equipped with a PADI dive centre, water skis, wakeboards, kayaks and fishing gear.
