Private Boat Hire in Koh Samui: All Options & Prices (2026)

Hiring a private boat in Koh Samui gives you complete freedom to explore the islands at your own pace. No fixed schedules, no rushing, no strangers on board — just you, your group, and the Andaman Sea. Here's everything you need to know about private boat charters in Koh Samui, from pricing to boat types to the best itineraries.

Types of Private Boats Available

At Samui Authentic, we operate two types of boats for private charters. Each has distinct advantages depending on your destination, group size, and budget.

Longtail Boats

Traditional Thai longtail boats are wooden vessels with a distinctive long propeller shaft extending from the stern. They're iconic to Thailand and offer an authentic, local experience.

Best for: Nearby islands like Koh Tan, Koh Madsum (Pig Island), Koh Rap, and coastal beaches within 30 minutes of Koh Samui.

• Capacity: Up to 10 passengers comfortably
• Speed: 15-20 km/h (moderate)
• Shade: Canvas canopy provides partial shade
• Comfort: Cushioned bench seating, more open to elements
• Character: Authentic Thai boat experience

We have 6 longtail boats in our fleet, all maintained to strict safety standards.

Speedboats

Modern speedboats are faster, more stable, and designed for longer trips. They're fiberglass vessels with powerful outboard engines.

Best for: Ang Thong Marine Park, Koh Tao, Koh Phangan, or any destination requiring speed and comfort.

• Capacity: 10-pax or 20-pax models
• Speed: 40-60 km/h (fast)
• Shade: Full canopy roof, sun deck area
• Comfort: Cushioned seating, ladder for easy water access, storage compartments
• Range: Can reach distant islands quickly

We operate 2 speedboats: a 10-passenger model and a 20-passenger model for larger groups.

Tips for Your Private Charter

• Communicate your priorities — tell us if you prefer more snorkeling, beach relaxation, or island exploration.
• Be realistic about timing — full-day charters typically leave at 09:00 and return by 16:00-17:00. Half-day charters are 4-5 hours.
• Bring reef-safe sunscreen — regular sunscreen damages coral. Available at dive shops if you forget.
• Pack light — boats have limited storage. Bring a waterproof bag for valuables.
• Ask about lunch options — we can arrange beachside restaurant stops or prepare a BBQ on a private beach.
• Check weather forecasts — we monitor conditions closely and will advise if a trip should be rescheduled.
