Yacht charter Koh Samui immerses you in Thailand’s Gulf of Thailand jewel – a lush, coconut-palm-covered island where the golden Big Buddha surveys Bophut’s Fisherman’s Village from a hilltop perch, the Five Islands’ granite boulders tumble into jade-coloured shallows, and the night market at Chaweng sizzles with pad thai and mango sticky rice as fairy lights sway in the warm evening breeze. Koh Samui draws from Thailand’s fleet of over 50 charter yachts: 68′–98′ motor yachts that cruise the short passage to Koh Phangan and Koh Tao, 100′+ superyachts anchoring in the deeper waters off Chaweng Noi, and 55′+ catamarans ideal for the calm, reef-rich anchorages of Ang Thong National Marine Park’s 42 islands.
December to April is peak season – dry, 28–32°C days with steady Gulf breezes and excellent snorkelling visibility. The shoulder months of May and November deliver warmer water, dramatic sunsets after brief tropical showers, and more negotiable rates. Daily rates start from approximately $3,500/day, rising to $7,500+/day on the latest-model yachts above 78′, plus 7% Thai VAT and 30–35% APA for fuel, provisions, and marine-park fees. Koh Samui’s irresistible appeal is the blend of boutique luxury and raw island character – a place where five-star wellness spas sit alongside coconut groves, and you can cruise to a deserted lagoon inside a volcanic island at Ang Thong by morning and return to a beachfront cocktail bar in time for sunset.

For the peak December–April dry season, five to seven months’ lead time is recommended, especially over the Christmas–New Year period and during the Full Moon Party weeks on neighbouring Koh Phangan. The shoulder months of May and November offer excellent value and can typically be arranged three to four months ahead.
The base fee covers the yacht, professional crew, insurance, and standard equipment including snorkelling gear. Fuel, provisions, beverages, Ang Thong Marine Park entry, and any dive excursions at Koh Tao are funded through the APA (30–35% of the charter fee). Thai VAT at 7% applies, and any unspent APA is refunded at the end of the voyage.
Yes – and it’s the definitive Gulf of Thailand yacht itinerary. Ang Thong’s 42 islands lie just 15 nautical miles north-west, while Koh Tao’s world-class dive sites are roughly 35 nautical miles further north. A seven-day charter covers all three with generous time for kayaking Ang Thong’s hidden lagoons, diving Koh Tao’s Sail Rock, and exploring Koh Phangan’s quieter northern beaches.
Koh Samui is superbly family-friendly. The calm Gulf waters are ideal for young swimmers, kayaking through the emerald lagoons of Ang Thong captivates children of every age, and the island’s elephant sanctuaries, monkey shows, and coconut-ice-cream stalls provide fun shore excursions. Crews are experienced at adapting menus, pace, and water activities for younger guests.
