Departing from Salakphet Bay on Koh Chang's quiet southeast corner, our sailors — almost all complete beginners working toward ASA 101 and ASA 103 — learn to sail in one of the calmest, most uncrowded sailing grounds left in Asia. Over seven days aboard a Lagoon 421 catamaran, you'll cross the Gulf of Thailand to the outer islands of the Koh Chang Archipelago: Koh Wai's coral gardens, Koh Mak's coconut backroads, Koh Kood's jungle waterfalls, and the marine-reserve silence of Koh Rang. The northeast monsoon delivers reliable 10–20 knot breezes and almost no rain from November through April. Twelve to twenty-five nautical miles between stops, sheltered anchorages every night, and a max of six sailors aboard — the conditions are forgiving enough to build genuine confidence and beautiful enough that nobody wants the week to end. If you've been looking for a learn to sail vacation in Thailand — real certifications, real islands, real Thai food — this is it.

Why Choose Sailing Virgins for Your Thailand Sailing Course?

Southeast Asia's Quietest Sailing Destination

While Phuket and Koh Samui are saturated with charter traffic, the outer Koh Chang Archipelago — Koh Mak, Koh Kood, and the Koh Rang marine reserve — sees a fraction of the boats. Most days you anchor with no one else in the bay.

ASA 101 + 103 Certification in One Week

Earn ASA 101 (Basic Keelboat) and ASA 103 (Coastal Cruising) — globally recognised certifications that qualify you for bareboat charter worldwide.

No prior experience needed. The northeast monsoon sea state is gentle (0.5–1.5m swell) and passages between islands are short, so confidence builds fast.

NE Monsoon Reliability — November to April

Steady 10–20kt breezes from the northeast, almost no rain, daytime temperatures 25–30°C, water 28°C. December and January average just 2–6 rain days a month — the most reliable sailing weather in tropical Asia.

World-Class Thai Food, Every Night Ashore

Salakphet seafood on the pier where it was landed that morning. Koh Mak Art House cooking by the family who built the place. Beachside grills on Koh Kood. The food alone is worth the flight.

Six Sailors, Perfect at Five

A Lagoon 421 catamaran is wide, stable, social, and forgiving — the easiest boat in the world to learn on. With a maximum of six sailors and one ASA-certified instructor, everyone gets enough helm time to actually leave knowing what they’re doing.

Experience the Gulf of Thailand Like Almost Nobody Has

Every morning begins with stillness. You wake at anchor in a bay where the only sound is the halyards tapping the mast and the occasional longtail boat heading out to fish. After the 7-7-7 routine and a swim off the back, you take coffee on deck while your instructor lays charts on the cockpit table and walks the crew through the day's passage — wind angles, tidal set, the rocky shoal off Koh Mak's pier.

Afternoons are spent under sail. Twelve to twenty-five nautical miles between islands means you get genuine sailing — not just motoring — and enough chart work to actually understand what coastal cruising is. By late afternoon you're anchored somewhere new: maybe the wide sand crescent of Koh Wai, maybe the marine-reserve quiet of Koh Rang where the stars come out so bright you can read by them.

Evenings are why people come back. Salakphet Seafood on the pier where the catch landed that morning. Live music at the Koh Mak Art House. Sunset cocktails at Cococape with the catamaran framed perfectly behind. Sailing in the Gulf of Thailand isn't just a course — it's the food, the water, the Thai welcome, and the rare modern luxury of an empty horizon.

Why Sail the Gulf of Thailand

The Koh Chang Archipelago sits on Thailand's eastern seaboard, just south of the Cambodian border, far from the cruise ships and charter fleets of Phuket. It's the inverse of the Andaman side: when the southwest monsoon makes the west coast of Thailand unsailable from May to October, the Gulf settles into the most reliable sailing weather in tropical Asia. November through April is dry, breezy, and warm — and the fifty-two islands of the archipelago are spread across just over a hundred nautical miles of forgiving cruising ground.

Variety is the second reason to come. In a single week you anchor off uninhabited reefs at Koh Wai, eat dinner with locals on Koh Mak, dinghy up a jungle estuary to a waterfall on Koh Kood, and spend a night under the stars in the no-take marine reserve at Koh Rang. The passages between are short enough to be approachable for first-time sailors and substantial enough to teach real ASA 103 navigation — chart work, position fixing, watch rotation, anchoring on sand in 8m.

And then there's the Thai part. Salakphet is a working fishing village with a seafood restaurant on the pier and a single road in. Koh Mak has bicycles instead of cars and an Art House that puts on live music nightly. Koh Kood has resorts that won't break the budget and a waterfall hike that ends in a swimming hole. The country, the food, the warmth — Thailand is one of the great destinations on its own. Sailing it is the version most travellers never see.

📍 Bangkok → Salakphet Bay, Koh Chang

Meeting time: Saturday at 5:00 PM*
*Some upcoming courses start on a different day — check your specific course date for the exact schedule.

Fly into Bangkok Suvarnabhumi (BKK). We meet you at the airport with a private van for the 4.5-hour transfer to Salakphet pier on Koh Chang's southeast corner. Board the Lagoon 421, settle in, run a safety briefing, and get the ASA 101 introduction over a sundowner at Salakphet Seafood — the village restaurant on the pier where everything comes off the boats that morning. Night one is at anchor in the bay.

What Do You Need to Know About Sailing in Thailand?

Which airport do I fly into?

Bangkok Suvarnabhumi (BKK), not Phuket. We provide a private van transfer from BKK direct to Salakphet pier on Koh Chang — about 4.5 hours each way. Plan to arrive in Bangkok the day before; the van leaves early. We can recommend Bangkok hotels close to the pickup point.

I've never sailed before. Can I do this?

Yes — most of our sailors here are complete beginners. The Gulf of Thailand is the gentlest place to learn in tropical Asia: short passages, sheltered anchorages, light to moderate winds, and a Lagoon 421 catamaran that is genuinely forgiving. You leave the week with ASA 101 and ASA 103 — the same certifications that qualify you for bareboat charter worldwide.

When is the best time to come?

The programme runs November through April only — the northeast monsoon. December and January are the driest and coolest months (averaging 2–6 rain days each); February and March bring lighter breezes that suit beginner-heavy crews. May to October is the southwest monsoon, when ferries to the outer islands suspend service and the weather is too unsettled to teach in.

How much cash should I bring?

Plan on 15,000–20,000 Thai Baht in cash per sailor (roughly $400–$550). ATMs on the outer islands are limited and unreliable, and you’ll want cash for shore dinners, optional dives, taxis, and cocktails. Pull baht from an ATM in the BKK arrivals hall — the exchange rate is better than at home or at the pier.

What should I pack?

Soft duffel only — no hard luggage, the cabins are tight. Quick-drying shorts and shirts, swimwear (×2), reef-safe sunscreen (mandatory in Mu Ko Chang Marine Park), polarised sunglasses with a backup, a light rain jacket, water shoes for reef and beach landings, insect repellent for evenings ashore, any personal medications, and a passport valid for at least six months from departure.

What does the food situation look like?

Breakfast, lunch, and snacks are aboard every day — fresh fruit, Thai coffee, light Thai-style lunches. Dinners are ashore four nights of the week (Salakphet pier, Koh Mak Art House, Koh Kood beach restaurants, Koh Mak again on the return) and aboard the other two. Budget around $12–$20 per shore dinner — Thailand is excellent value. Drinks ashore aren't included.

How do the ASA certifications work?

You earn ASA 101 (Basic Keelboat) and ASA 103 (Coastal Cruising) over the week. Theory is taught daily on deck and through the practical exercises; written exams are short and given on Day 6. Both certifications are recognised by ASA-affiliated charter companies worldwide and qualify you for bareboat charter on a 30–45ft yacht in many destinations.

Is this a vacation or a serious sailing course?

Both — that's the point. It's a learn to sail vacation in Thailand: you earn ASA 101 and ASA 103 through daily hands-on instruction, and the classroom happens to be the Koh Chang Archipelago — snorkeling at Koh Wai, a waterfall hike on Koh Kood, and Thai dinners ashore most evenings. Instruction, accommodation aboard the catamaran, and certification exams are all included.

What do people do after the week?

Many sailors fly back to Bangkok for a couple of nights to eat their way through the city — Chinatown street food, the rooftop bars, the temples. Others connect on to Chiang Mai, Phuket, or Singapore. The van transfer drops you at BKK, so onward flights are easy. We can suggest hotels in Bangkok and route ideas if you want help.
