An established yacht with eight ensuite cabins

Built in 1977, Thailand Aggressor joined the destination programme in 2013 and returned after a 2024 refit. Her 35 m length and 7 m beam give the boat a substantial footprint, although this remains a classic liveaboard rather than a new resort yacht. The current cruising speed is nine knots.

Three Master cabins have queen beds: numbers 2 and 3 are on the main deck with picture windows, while number 1 sits below with portholes. Five Deluxe cabins, numbers 4–8, offer separate twin beds on the main deck. All eight have private bathrooms and individual air conditioning. Couples may favour a Master; friends sharing a room generally have a simpler arrangement in a Deluxe.

The quieter moments between dives

The original Divezone review picked out the partly shaded sundeck, wet bar and hot tub, and those remain central to the boat’s appeal. The indoor lounge offers a cooler retreat for a book or a fish-identification discussion. There is room to enjoy the sea without turning every surface interval into another activity.

Cooked-to-order breakfasts, buffet lunches and served dinners set a reassuring rhythm. The sample menu moves between Thai curries, grilled dishes and familiar Western meals, with snacks between dives. Dietary needs belong in the booking conversation; a remote boat cannot promise every specialist ingredient. Local beer and wine are included, with alcohol reserved for after the day’s diving.

North or south: two seven-night journeys

Both programmes run Saturday to Saturday, with diving from Sunday until Friday. The northern season centres on the Similans, Koh Bon, Koh Tachai and Richelieu Rock; northern logs also document Surin island dives. The southern week explores the limestone islands and reefs around Phi Phi and Koh Haa, with the wider programme also advertising Hin Daeng. Up to 24 dives and an island visit are planned, subject to conditions.

Route descriptions below.

1. North: Thap Lamu area (1) → Similan Islands (2) → Koh Bon (3) → Koh Tachai (4) → Surin Islands (5) → Richelieu Rock (6), returning through the northern islands to Thap Lamu. November–April is the operator’s core northern season.
2. South: Phuket area (7) → Phi Phi (8) → Koh Haa (9) → Phi Phi → Phuket. This illustrates the island sequence documented on the 26 September 2026 departure; other southern weeks may visit Hin Daeng and other sites. May–October is the advertised southern season.

The map shows regional planning references and indicative connections, not navigation tracks or exact boarding points. Actual stop order, repeat dives and crossings change with the conditions. The southern map is an observed example, not a promise that every departure follows that week.

The current northern boarding point is Andaman Sea Sun Travel Pier in Thap Lamu; southern trips use Visit Panwa Pier in Phuket. Phuket International Airport serves both. Scheduled transfers operate on charter dates, with arrangements requested at least seven days ahead. The host hotel and pickup time differ by route, so the booking confirmation matters more than an old generic pier label. Checkout is at 08:00 on the final Saturday.

A budget with the park charge included

Standard 2026 and 2027 fares are US$3,490 per person for seven nights, based on two people sharing either a Deluxe or Master cabin. Promotions and currency quotes vary by departure. The operator lists a US$95 park charge plus 7% VAT on that charge and onboard purchases.

The rental example adds the advertised US$175 set; it includes a BCD, regulator, computer, night light, mask, fins and snorkel, but not a wetsuit. A seven-night wetsuit rental is listed at US$50 before local tax. Airfare, hotels, insurance, tips and other personal spending remain outside these totals. The quote at booking establishes the final inclusions and charges.

A guaranteed private cabin carries a 65% single supplement on the full fare under the operator’s standard policy. A solo traveller willing to share should therefore compare the actual shared-cabin availability before pricing the entire room. Special offers have separate conditions.

Tender diving, cameras and practical preparation

All dives use skiffs, with the yacht’s dive deck providing personal equipment storage, rinse facilities and camera workspace. This is a good arrangement for photographers who appreciate help between boat and tender, but confidence with tender entries and exits still matters.

Air cylinders, weights and belts are included. Current operator information lists Thailand Aggressor as compatible with both DIN and K valves, replacing the old DIN-adapter-only advice. A dive computer is required; an SMB with reel or spool is required for tender diving. Nitrox is available to certified users at US$100 for seven nights before local tax. Buddy teams remain responsible for their dive planning within their certification, experience and briefing limits; a private guide is not offered under the fleet’s current policy.

Certification, recent experience and any medical or insurance requirements should be settled with the operator before payment. A week with many optional dives is more enjoyable when the schedule suits the diver; the advertised maximum is never an obligation to join every dive.

For a travelling companion who does not dive

Non-divers and snorkellers are accepted. The standard liveaboard non-diver reduction is US$200 off the fare, excluding consumer specials and unique adventures. It is not a free companion place, and the booking quote must state the remaining fees. The lounge, deck and hot tub provide genuine downtime, while the advertised island visit adds some time ashore. Snorkelling access depends on the site and conditions; this is still a diving-led itinerary, without a separate daily excursion programme promised.

What recent guests enjoyed—and what to weigh up

Our reading: Thailand Aggressor makes most sense when service, ensuite accommodation and a full seven-night programme justify the higher total spend. Someone prioritising a very new vessel, large cabins or a short break may find a different Thai boat a better fit. Read the dated guest accounts.
