Master Liveaboards

Komodo, Raja Ampat, Ambon & the Philippines · Indonesia

Formerly Siren Fleet / Worldwide Dive and Sail. Same operation under a new name — worth knowing if you are holding an older recommendation.

A liveaboard operator running wooden phinisi-style yachts across eastern Indonesia and the Philippines, on itineraries that reach reefs no day boat can.

Komodo, Raja Ampat, Ambon & the Philippines

Why they are on this list

Five trips between 2012 and 2017, when they still traded as Siren Fleet: Komodo, Raja Ampat to Ambon, Tubbataha, Malapascua and the Visayas, and Raja Ampat a second time. The Siren name is gone; the operation is the same one.

What you can see there

No affiliate links, no commission, no paid placement. This list is short because it only holds operators I have actually dived with — including the ones that are gone.
