All About The The Phinisi

A Purpose-Built Phinisi for Similan Diving

While many phinisi-style boats are converted sailing vessels, The Phinisi was purpose-built in Indonesia for diving. This design approach means thoughtful details throughout the boat — from wide staircases to tank storage and rinse tanks — all configured to meet the needs of divers.

Its two-mast schooner appearance blends traditional wooden boat charm with modern engineering, making it one of the more unique Similan liveaboard choices in the region.

Comfort Above and Below Deck

The boat offers seven cabins: flexible twin, double, and quad configurations — all with en-suite bathrooms and air-conditioning. Interiors are warm and wood-paneled, reflecting the boat’s classic style while maintaining comfort. Cabins are cleaned daily, and space is optimized well for storage and ease of movement.

Communal areas include a covered outdoor dining area, an indoor saloon, and multiple sundecks for relaxing between dives or enjoying the sunset over the Andaman Sea.

A Dive Deck Designed by Divers

Divers will appreciate the dedicated dive deck, which is well laid out to avoid crowding. The platform includes rinse tanks, storage space, a camera station, and nitrox availability. Gear setup is made easy, and the dive team ensures smooth scheduling, safety briefings, and entry/exit procedures.

Itineraries cover the top dive sites in the Similan and Surin Marine Parks, including Richelieu Rock, Koh Bon, Koh Tachai, and the Similan Islands. The Phinisi typically runs 4- or 6-night trips during the high season (October–May), timed to explore each area in depth.

The Crew and Experience

The Phinisi is operated by the same experienced team that runs The Junk, one of Thailand’s most iconic liveaboards. Expect the same high standard of service, dive professionalism, and hospitality, backed by years of experience operating in Thai waters.

The onboard chef prepares Thai and Western dishes, often buffet-style, and special dietary requests can be accommodated with advance notice. Guests often comment positively on the food quality and variety.

Who It’s For

If you’re looking for a Similan liveaboard with character and luxury, The Phinisi delivers. It suits underwater photographers, couples, dive clubs, or solo divers looking for a well-run and stylish dive trip. It may not be the most high-tech vessel in Thailand, but its balance of authenticity, comfort, and dive focus makes it a standout.
