Speedboat Rental Koh Samui – Private Boat Charter & Island Trips.

Rent a boat in Koh Samui with Siam Boats for a private island trip with captain and crew. Visit Pig Island and Koh Tan on a half-day outing, explore Koh Phangan or plan a full-day adventure to Ang Thong National Marine Park, Koh Tao and Koh Nang Yuan.
Your private speedboat charter is exclusively for your group. Enjoy swimming, snorkeling and beach stops, with your route and departure arrangements agreed before booking.

Private Boat Rental in Koh Samui with Captain & Crew
A speedboat is a practical choice for island hopping, helping you cover longer distances and combine several stops in one trip. Couples, families and friends can enjoy their own private boat tour without joining a shared group excursion.
For example, Diamante is a twin-engine speedboat based in Koh Samui, offering private island trips ranging from half-day visits to Pig Island and Koh Tan to full-day adventures in Ang Thong National Marine Park.
