There is a particular quality to leaving Phuket's east-coast marinas before dawn — the lights of Phang Nga Bay still glowing behind you, a sport-fisher pushing through flat black water toward open ocean. By the time the sun clears the limestone karsts, you are already beyond sight of land, scanning the horizon for frigate birds circling above a bait school. That is when a full-day big-game trip earns its price.
Why a Full Day Is Non-Negotiable
Half-day fishing trips have their place in Phuket — reef trolling inside the bay, bottom fishing near Racha Yai, light-tackle fun for families. But genuine big-game fishing operates on a different geography. The productive offshore grounds — the seamounts, current edges, and blue-water channels where sailfish and marlin hunt — sit 20 to 40 nautical miles from Chalong Bay or the east-coast marinas.
A capable sport-fisher runs 25–30 knots. Even so, transit consumes 60 to 90 minutes each way. On a five-hour half-day trip, that leaves barely two hours of active fishing time. On a full-day charter departing at 6:30 a.m. and returning around 5:00 p.m., you get four to six productive hours on the grounds. That difference is the line between a sightseeing cruise and a serious fishing day.
Full-day trips typically depart between 6:00 and 7:00 a.m. from Boat Lagoon or Royal Phuket Marina and return by 4:30–5:30 p.m. Factor that into your broader Phuket itinerary.
Target Species
Sailfish
The Indo-Pacific sailfish is the defining species of Phuket's big-game season. From November through February the northeast monsoon pushes warm blue water up against the Andaman shelf, concentrating baitfish and the sailfish that chase them. Bills up to 60 kilograms are not unusual. Trolled lures, rigged ballyhoo, and live bait all produce — experienced deckhands will switch methods depending on conditions.
Marlin
Black marlin and blue marlin are present February through April when water temperatures peak. These are less common than sailfish and typically require longer runs to deeper water. A marlin encounter on a day trip is a bonus rather than a guarantee, but the chance is real and operators actively target them late-season.
Giant Trevally and Wahoo
GT popping is increasingly popular around offshore structure and reef edges. Many big-game boats now carry a set of surface poppers and stickbaits specifically for GT work. Wahoo are excellent table fish and fast fighters — they often attack trolled lures meant for sailfish. Read more about the GT fishery in our GT popping Andaman guide.
Mahi-Mahi
Dolphinfish appear wherever floating debris or weed lines gather offshore — common enough that most full-day trips boat at least a few. They are visually spectacular fighters and excellent eating, making them a crowd favourite even among non-anglers.
Typical Day Itinerary
5:45–6:15 a.m. — Meet at marina, board vessel, brief safety and fishing orientation from the captain or chief deckhand.
6:30 a.m. — Departure. Coffee and breakfast snacks served underway as the boat clears Chalong Bay.
7:45–8:30 a.m. — Arrival on offshore grounds. Lines deployed — typically four to six trolling positions using outriggers, flat lines, and a centre rigger. Lures, rigged naturals, and teasers set depending on captain's read of the water.
8:30 a.m.–2:30 p.m. — Active fishing. Lines adjusted based on conditions. Popping gear deployed around reef structure as opportunity arises. Crew handles all rigging; anglers rotate on rods.
2:30–3:00 p.m. — Lines in, begin return transit. Catch documented. Light snacks served.
4:30–5:00 p.m. — Arrival back at marina.
What's Included
A properly priced full-day big-game charter includes: all tackle, lures, and leaders; fuel; ice; light meals (breakfast snacks and a lunch box or sandwiches); water and soft drinks; fishing licences where required; and experienced crew of two to three. International sport-fishing safety standards — life rings, flares, VHF radio — are standard on licensed vessels.
What's Not Included
Alcohol is almost never included and often prohibited given safety requirements. Transfers to and from the marina are your responsibility — a taxi from Patong takes 30–45 minutes. Fish processing (cleaning, filleting, vacuum packing) may incur a small additional charge. Gratuities for crew — 10–15% of charter cost is the industry norm if you had a strong day.
"The productive offshore grounds lie 20 to 40 nautical miles from Chalong Bay. A full day gives you the transit time and the fishing time — you cannot have both on a half day."
Pricing
Big-game charter pricing in Phuket reflects fuel costs, vessel quality, and crew expertise. Expect to pay:
- Shared group trips (where a full boat is split among 4–8 anglers): $200–$500 per person depending on vessel and operator tier
- Private exclusive charter (you and your group have the boat): $800–$2,000 per day
The wide private charter range reflects enormous variance in vessel quality — a 35-foot centre-console diesel boat is a very different proposition from a 50-foot purpose-built sport-fisher with air-conditioned cabin, fighting chair, and full electronics. See our detailed Phuket charter prices guide for a full breakdown.
Beware operators quoting suspiciously low prices for "big-game fishing." Genuine offshore sport-fishing boats carry high fuel costs. A legitimate full-day private charter below $700 USD should prompt careful questions about vessel condition and tackle quality.
Transport to the Marina
Boat Lagoon Marina is approximately 35–40 minutes from Patong Beach by taxi (around 400–500 THB). Royal Phuket Marina is slightly closer to the airport and Phuket Town. Most charter operators will provide marina gate access instructions when you confirm your booking. Rideshare apps (Grab) work well for this route.
What to Bring
The golden rule for offshore fishing is sun protection and motion-sickness preparedness. Even on calm Andaman days, a boat running 25 knots creates wind chill and spray exposure.
- Sun protection: high-SPF reef-safe sunscreen, sun-protective shirt (UPF 50+), polarised sunglasses, wide-brim hat
- Motion sickness: take medication the night before if you are prone — once offshore, it is too late
- Footwear: soft-sole non-marking shoes; bare feet on wet decks is a fall risk
- Layering: a light windproof layer for the early transit; mornings can be cool at speed
- Camera: waterproof or in a dry bag; a lanyard for phone cases

Who This Trip Suits
Full-day big-game fishing is the right choice for anglers who have travelled specifically to fish and want the best realistic chance at a sailfish or marlin. It suits couples and small groups (2–4 people) who want an exclusive experience, and larger groups (up to 8) on shared charters who are comfortable meeting other anglers on the boat.
It is not the right choice for families with young children, anyone with motion sensitivity, or guests who want a relaxed morning with guaranteed action close to shore. For those situations, see our half-day Phuket guide or family-friendly charter options.
Best Season
November to April is peak season and the only window most operators recommend for targeting billfish. December and January are statistically the top months for sailfish numbers. March and April extend the season with marlin possibilities.
The southwest monsoon (May–October) brings rough Andaman seas and most operators suspend offshore big-game operations. Some vessels pivot to the Gulf of Thailand during this period. For strategic alternatives, see our monsoon season fishing guide.
Booking Considerations
Book at least two weeks ahead during peak season (December–February), when quality vessels fill quickly. For a trip in January or during Thai holidays, a month's notice is advisable. Operators will typically ask for a 30–50% deposit at booking; read cancellation terms carefully, as weather cancellations are common and should result in full refund or rescheduling.

A full-day big-game trip out of Phuket is not a casual add-on to a beach holiday. It is a committed fishing day that asks something of you — an early alarm, a long transit, an open sea, and the patience to wait for a fish that can clear the water at 60 kilometres an hour. For anglers who make the commitment, it remains one of the finest sportfishing experiences available in Southeast Asia.
