Are Phuket Boat Tours Safe? The Rules, the Limits and What to Check

The 2018 sinking and what changed afterward

On 5 July 2018, the Phoenix, a tour boat carrying Chinese visitors, sank in a storm off Phuket, killing 47 people. It is public record, widely reported at the time, and it is the reason the checks now standard on the island exist in something close to their current form. In the aftermath, authorities tightened requirements around passenger manifests, listing names and photographs before departure, added equipment inspections by the provincial tourism office, and stepped up licence checks on both boats and captains.

That history matters for context, not for alarm. It explains why a modern Phuket boat tour asks for your name and photo before boarding, why crews run through safety equipment before the boat leaves the pier, and why a red flag at the harbour can hold departures that would have sailed a decade earlier without a second thought.

Life jackets and the flag system, in practice

Life jackets are mandatory for every passenger on a Thai tour boat, and operators brief the location and use of safety equipment before departure as a matter of course, not as an optional extra. Port officials use a red and green flag system to signal whether boats may sail from a given pier: a green flag means departures are cleared, a red flag means the port is closed to them, and that decision sits with the harbour authority, not with any single operator hoping to run its schedule as planned.

• Life jackets: mandatory for all passengers, briefed before departure
• Manifest checks: names and photographs recorded before boarding
• Flag system: red flag closes a pier to departures, overriding any operator's own plan
• Licensing: commercial boats must be licensed, and operating without a valid licence carries fines

Thailand's Marine Department sets the licensing and equipment rules that commercial tour boats operate under, and provincial tourism officials carry out the equipment checks that followed the 2018 tightening. The go, no-go call on any given morning combines that regulatory backdrop with the harbour authority's flag system and the operator's own read of the sea state, so no single party makes the decision in isolation.

Where this guide cannot go further is publishing a licence registry or an inspection log, since neither is released in a form this site can verify listing by listing. What is verifiable, and what genuinely matters more day to day, is what each operator states in writing about who can and cannot board, covered in full below.

Reading the table honestly

Phi Phi speedboat day tour publishes by far the most detailed list of the six, naming an age ceiling, a weight limit, and specific medical conditions where the others state a shorter list or none beyond pregnancy. That is not evidence the other operators are less careful; a shorter published list may simply mean fewer conditions have been formalised in writing, and a traveller with a genuine medical concern should ask the operator directly rather than assume silence means clearance.

A maximum passenger count is stated on two of the six listings: James Bond Island Sunset Cruise states a maximum of 95 passengers, and the speedboat tour above states 40 to 42 guests. The other four do not publish a capacity figure, and none should be assumed.

• Pregnancy: excluded on all six tours compared here, no exceptions stated
• Age: an upper limit (70 or 80) is stated on two listings; no listing states a strict minimum age
• Weight: an individual cap of 100 kg is stated on one listing; none publish a combined or tandem weight limit
• Wheelchair access: two listings state they are not set up for wheelchair users; none advertise wheelchair accommodation
• Heart, back, neck or mobility conditions: named on four of the six listings in varying detail

A day on open water carries a handful of genuine, specific risks, each with a specific response a well-run tour applies rather than a vague reassurance about safety being a priority.

• Rough seas on the open Phi Phi crossing: managed by the red and green flag system holding departures, and by operators' own free-cancellation policies rather than sailing regardless
• Motion sickness on a long speedboat day: the speedboat tour includes motion-sickness medicine, and the power catamaran tour recommends bringing your own; see how the tours handle weather disruption in our guide to what happens when a tour is cancelled
• Boarding and disembarking from the water at some stops, rather than a fixed dock: mitigated by mandatory life jackets and crew assistance at each stop
• Crowding at the busiest snorkel stops: a comfort issue rather than a safety one, covered honestly in our guide to whether the Phi Phi tour is worth it, not glossed over here

Sea state and the crossing that matters most

The Phi Phi crossing runs about an hour of open Andaman water, the most exposed leg any tour on this site makes; Phang Nga Bay's shallower, island-shielded routes cross in 30 to 45 minutes and hold up better in the same conditions. That geography is one reason a cancellation or a skipped stop is more common on the Phi Phi route in the wetter months than on the Phang Nga Bay circuit, and it is worth knowing before booking during the June to October stretch. The speedboat tour's own listing puts this in writing rather than leaving it implied: low season, June to October, is recommended only for guests comfortable with rough seas, because the ride is very bumpy in that window.

What a pre-departure briefing actually covers

The specific format varies by operator, but the substance is consistent across the tours compared here: where the life jackets are, how to put one on, where the exits and emergency gear sit, and what to do if a crew member calls for it. One tour runs its briefing inside a marina lounge before boarding rather than on the moving boat itself, which gives passengers a calmer setting to actually absorb it. None of the six listings publish the full script of their briefing, and that is normal; what matters is that a briefing happens before departure on every one of them, not after the boat is already moving.

What a traveller packs matters too. Our guide to what to bring on a Phuket boat tour covers the practical side of preparing for the day, including motion-sickness options and sun protection, separate from the safety rules covered here.

A traveller cannot inspect a licence registry directly, but a few things published on the listing itself are worth reading before you pay, not after.

• Read the exclusions on the specific listing, not a general assumption about boat tours; the table above shows they genuinely differ
• If you have a heart, back, neck or mobility condition, check whether it is named explicitly, and contact the operator directly if the listing is silent
• Note whether motion-sickness medicine is provided or only recommended, and pack your own if the listing does not supply it
• Check the cancellation policy; every tour compared here offers free cancellation up to 24 hours before departure
• If travelling in the June to October window, expect a bumpier ride on the Phi Phi crossing specifically, as the speedboat tour's own listing states in writing

None of this makes a Phuket boat tour risk-free, and no listing anywhere makes that claim honestly. What the record supports is a regulated activity, tightened meaningfully after a well-documented 2018 incident, running under mandatory life jackets and a flag system that can hold a departure when conditions call for it, alongside a published set of exclusions that genuinely narrow who each tour is suitable for. Reading the specific listing's restrictions before booking, rather than assuming boat tours are interchangeable, is the one step within a traveller's own control. The Phuket boat tours we compare each publish their own terms; check the one that fits before you pay.
