The bathroom matters more than the cabin label

All 15 cabins have air conditioning. Eleven have private bathrooms; the four Budget cabins use separate shared facilities. The useful comparison is between Standard’s flexible beds downstairs and Deluxe’s bunk beds with a main-deck sea view. A higher category does not automatically mean two beds side by side.

Master and Deluxe rooms have larger sea-view windows; Standard rooms have a small porthole. Budget rooms differ by deck, so the cabin number and window arrangement deserve confirming. Solo sharing is available in several categories. The published private-occupancy calculation is one diver fare plus one non-diver fare, which is a significant step up from buying a single berth.

A large saloon, with the sea just outside

The boat’s main indoor lounge is spacious, located on the upper deck, right by the wheelhouse. Big windows keep the island scenery in view, while the covered dining area opens towards the stern. Upstairs, shaded and open lounging spaces give sun lovers and readers different places to settle between dives.

Thai and international buffets follow a busy diving day, with an early snack, breakfast, lunch, afternoon food and dinner. Vegetarian meals and other dietary arrangements are available by prior request. Drinking water, tea, coffee, fruit and snacks are included; soft drinks and alcohol are extra. Wi-Fi uses the Thai mobile signal, so it is an occasional convenience offshore rather than a dependable working connection.

Four dives can make a wonderfully full day

A broad preparation deck, individual equipment space and rinse facilities support a programme of up to 14 dives. Air cylinders, weights and guiding are included, as are nitrox fills for already-certified nitrox divers. Regular groups are generally around five or six divers per guide, with the actual grouping shaped by experience and the people aboard.

The current booking itinerary lists Open Water certification and four logged dives, but its detailed conditions also require Advanced Open Water or a Deep specialty, arranged in advance if needed. Junior Open Water and Junior Advanced divers require a private guide rather than joining a standard group. Those conditions matter more than the reassuringly low minimum in the headline. Included accident and recompression cover also has policy limits; its terms need comparing with the diver’s own insurance requirements.

One northern circuit, with time at Richelieu Rock

The published 2026–2027 schedule follows one principal four-night itinerary from Thap Lamu back to Thap Lamu. It is sometimes sold as four days/four nights and sometimes five days/four nights: both descriptions include the first evening aboard, followed by four diving days. There is no separate southern or Myanmar route in the current regular programme reviewed here.

Route description remains available while the map loads.

Approximate trip-planning outline, not a navigation track or guaranteed daily schedule. Weather, park access, guest experience and the captain’s decision can change the sites.

Route: 1 Thap Lamu → 2 Similan Islands → 3 Koh Bon → 4 Koh Tachai → 5 Richelieu Rock → Koh Tachai and Koh Bon → Thap Lamu. The first diving day stays among the Similans, the second moves north, and the third concentrates on Richelieu. Two dives on the final morning round off the trip before the return to shore.

The repeated stops are part of the appeal: a pinnacle can reveal different fish activity or light on a return dive. The sample Similan day includes Princess Bay, West of Eden and Elephant Head Rock, with a beach visit when possible. Marine-life encounters remain possibilities, including mantas around Koh Bon and whale sharks at Richelieu, rather than a promise tied to a date.

A walkthrough before choosing a cabin

A four-night fare with nitrox already included

These 2026–2027 reference fares are Thai baht per person sharing, including VAT. They provide a consistent comparison between cabin categories; promotions and the selected departure can produce a different quote.

National park fees add THB2,300 per diver or THB1,500 per non-diver. A Budget diver’s cabin-plus-park subtotal is therefore THB37,000; the corresponding non-diver subtotal is THB33,200. Meals, scheduled transfers, air cylinders and weights, diving and certified nitrox fills are included. Equipment hire, courses, private guiding, paid drinks, flights and personal insurance costs sit outside those subtotals.

Rental equipment is quoted differently by booking supplier. One current package lists THB3,200 for the four-day set, excluding computer and torch. The useful comparison is the written total for the equipment actually needed, including the number of rental days. Published terms also allow fuel-related price changes, so the final departure quote remains important even when no fixed fuel charge appears in the current mandatory-fee list.

An evening departure from Khao Lak’s harbour

Scheduled minibus collection runs from late afternoon into the evening across Phuket and Khao Lak. Boarding is at Thap Lamu, followed by dinner and the overnight passage to the Similans. The last day normally reaches the pier in mid-afternoon; the hotel transfer then takes additional time. The booking confirmation’s pickup point matters more than a generic Phuket departure label.

There are two dives on the last morning. The operator-provided itinerary recommends 24 hours between the final dive and flying, making a night ashore the straightforward way to finish the cruise without rushing the no-fly interval.

A partner can join without a dive certification

The published non-diver fare is THB3,000 below the diver fare in each cabin category, with a lower park fee as well. The large lounge, open decks and possible beach visit give companions time to enjoy the islands. Snorkelling and swimming depend on the stop and conditions; offshore pinnacles are not all suitable for a relaxed surface outing. A dedicated daily snorkelling guide or separate excursion programme is not confirmed in the regular package.
