Koh Samui Yacht Charters — Private Boat Trips, Island Hopping & Luxury Cruises

Koh Samui is built for days on the water. Thailand’s second-largest island sits in the warm Gulf of Thailand, ringed by palm-backed bays and within easy reach of some of the country’s most beautiful marine parks. The catch? The best of it — the hidden lagoons, the empty snorkelling reefs, the beaches you reach only by boat — isn’t on the shuttle-bus itinerary. It’s offshore.

That’s where we come in. Oceans Elite Charters runs private yacht, catamaran and speedboat charters across Koh Samui and its surrounding islands, with a full crew, a route you help design, and the kind of first-class, safety-first service that turns a day trip into the highlight of the whole holiday. Whether you want a fast adventure, a slow sail, or a celebration nobody forgets, your boat is yours for the day — no strangers, no fixed schedule, no compromise.

What is a Koh Samui charter, and is it worth it?

A Koh Samui yacht charter is a private boat rental with a professional captain and crew that takes you island-hopping, snorkelling and sightseeing around Koh Samui’s nearby islands at your own pace. It’s worth it because you get privacy, flexibility and access to spots the big group tours skip — and the day usually includes hotel transfers, lunch, snorkelling gear and refreshments. Charters run from half-day sunset cruises to full-day island trips and overnight voyages.

Why explore Koh Samui by private charter

Anyone can book a seat on a crowded speedboat. A private charter is a different thing entirely.

You set the pace. Linger an extra hour at a snorkelling reef, skip a stop you’re not feeling, swim until you’re done — the day bends around you, not the other way round. You also reach places the day-tour fleets can’t or won’t: quiet anchorages, smaller islands, beaches that are briefly, blissfully your own. And because it’s just your group on board, a charter suits almost any occasion — a couple’s escape, a multi-generation family reunion, a stag or hen party, a milestone birthday, or simply a Tuesday that deserves to be remembered.

There’s also the boat itself. Our fleet ranges from sleek motor yachts and stable sailing catamarans to quick, nimble speedboats, most with sun decks, shaded lounges, sound systems and room to spread out. Add a crew who genuinely know these waters — where the fish are biting, which grotto to hit before the crowds, which beach is best at low tide — and you have a day that feels effortless from hotel pickup to the moment you step back onto the dock.

Our Koh Samui charter experiences

Every charter is tailored, but these are the routes our guests love most. Each can be run on a yacht, catamaran or speedboat, depending on your group size and budget.

Ang Thong National Marine Park

A protected archipelago of 42 islands of jagged limestone, hidden lagoons and jungle-green peaks — roughly 45 minutes by boat from Koh Samui. Expect dramatic grottoes, viewpoints, kayaking, snorkelling and a seafood lunch ashore. It's the single most photogenic day out in the region, and on a private charter, you beat the tour armada to the best beaches. Explore the Ang Thong Marine Park charter

Koh Tao & Koh Nang Yuan

A bucket-list run for snorkellers and divers. Koh Tao is famous for clear water and abundant marine life, while neighbouring Koh Nang Yuan is a trio of islets joined by a single sandbar — one of the most photographed views in Thailand. A full-day yacht charter gives you time to actually enjoy both rather than rushing through.

Koh Tan & Koh Madsum (Pig Island)

Close to Koh Samui's south coast and ideal for a relaxed half or full day. Koh Madsum, better known as Pig Island, is home to friendly resident pigs that paddle out to greet boats, while Koh Tan offers some of the best easy-access snorkelling reefs nearby. A favourite with families and first-time snorkellers. Discover the Koh Tan & Pig Island charter →

Koh Phangan — the Oceans Voyager

Explore Koh Samui's larger neighbour by sea: secluded bays, snorkelling stops, beach time and a local lunch, often with a sunset on the cruise home. Famous for the Full Moon Party, but by day Koh Phangan's coastline is quiet, green and gorgeous. See the Oceans Voyager itinerary →

Oceans Sunset — the sunset cruise

Our half-day evening itinerary: cast off in the late afternoon, anchor in a calm bay for a swim, and watch the Gulf of Thailand turn gold and pink with a drink in hand. Romantic for couples, easy and elegant for groups and celebrations. Book the Oceans Sunset cruise →

Oceans Overnight — sleep aboard

The ultimate slow escape. Spend the night on a luxury yacht or catamaran, anchored under the stars, waking up to open water and breakfast on deck. For honeymoons, anniversaries and anyone who wants to truly switch off. Explore the Oceans Overnight charter →

Party yachts & private celebrations

Birthdays, bachelor and bachelorette parties, corporate days, family reunions — bring the music, the drinks and the people, and cruise the islands with sound systems, lounges and sun decks made for celebrating. We've hosted large groups for milestone events and tailored the whole day around the occasion. See our luxury party yachts →

Deep-sea fishing charters

Available year-round, day or night. Target species in these waters include barracuda, mackerel, snapper, trevally, grouper, cobia and sailfish. Charters typically include fishing and snorkelling gear, life vests, a Thai buffet lunch, snacks, fruit, soft drinks and hotel transfers — and yes, the crew can prepare your fresh catch on board.

Best time to visit Koh Samui (and when to sail)

Koh Samui has its own weather rhythm, slightly different from much of Thailand. As a quick guide:

The short version: December to April delivers the calmest, clearest water and the most reliable island-hopping. That said, the shoulder months are often a sweet spot — warm seas, thinner crowds and better rates. Deep-sea fishing runs all year.

Sample itineraries

Full-day island-hopping (approx. 8 hours). Hotel pickup → cruise to your first snorkelling reef → swim and explore → secluded beach stop → fresh lunch on board or ashore → second snorkelling or viewpoint stop → relax on the sun deck → return cruise (sunset upgrade optional) → hotel drop-off.

Half-day escape (approx. 4 hours). Hotel pickup → nearby island and reef → swim, snorkel and beach time → refreshments and fruit on board → return. Perfect for Koh Tan / Koh Madsum or a sunset run.

Overnight voyage. Afternoon departure → sunset anchorage and dinner → night aboard under the stars → sunrise, breakfast and a morning swim → leisurely cruise home.

Every itinerary is a starting point — tell us your priorities (snorkelling, relaxing, partying, photos, fishing) and we’ll shape the day around them.

How much does a Koh Samui yacht charter cost?

Charter prices in Koh Samui depend on the boat, the season, the group size and the route. As an indicative guide:

Because charters are private, the per-person cost drops sharply with bigger groups — a luxury yacht split between 10–12 people is often comparable to a premium seat-in-coach day tour, with infinitely more freedom.
