The fleet includes the Boonsiri Fantasea, with state-of-the-art computer-controlled stabiliser aluminium catamaran construction for up to 200 passengers across two decks. In good weather it cruises at 25 knots. The newer Haad Thanam holds 288 passengers across three decks, including a VIP room for 30 passengers and an open upper deck for 56. On board there is air conditioning, tinted windows, adjustable seating, a small shop, large-screen TVs and free Wi-Fi.
