Motor catamaran "Super King"

The afternoon half-day charter has the same two island stops at a slower pace, with warm water and golden light for the return. It is a good fit for families and small groups who prefer a later start.

You snorkel the coral at Koh Tan, then spend time on Pig Island with the resident pigs, the sand and the paddleboards. The cruise home is a relaxed one on deck.

A full day on the water with three stops. You snorkel Koh Tan, visit the pigs on Koh Mudsum, then continue to the quiet island of Koh Rab for a swim, a walk on the sand and a long unhurried afternoon.

With 8.5 hours aboard, there is time for fishing, paddleboarding, lunch on deck (bring your own or add a BBQ set) and a rest in the cabins or saloon.

This full-day charter combines Koh Tan's reefs and Pig Island with the clear water and white sand around Koh 4 and 5. It suits groups who want plenty of swimming and snorkeling in one day.

The crew sets the pace and you choose how to spend it: snorkeling, paddleboarding, fishing or resting on deck.

Spend a full day in Ang Thong National Marine Park, an archipelago of limestone islands, hidden lagoons and turquoise bays northwest of Koh Samui. A private catamaran lets you stop where and when you like, away from the crowds.

You can snorkel, paddleboard, fish and swim between islands. The park entrance fee is paid separately.

Sleep aboard the Super King on a private overnight charter in the Gulf of Thailand. The boat has three cabins, a saloon and wide decks. You anchor in a sheltered bay for the night under the stars, with sunset and sunrise from the water.

Day one covers Koh Tan and Pig Island, and the night is spent at anchor near Ang Thong National Marine Park or a calm bay nearby. The next morning you can swim, snorkel or paddleboard before cruising home. Captain, crew, guide, snacks, drinks, fruit and equipment are included. Meals are not, so bring your own or add a BBQ set.

A three-day private expedition for those who want to go beyond the usual day-trip circuit. The first night is spent at anchor in Ang Thong National Marine Park or at Phaluai Island. The second night is near Koh Tao, with its clear water and some of the Gulf's best snorkeling.

You live aboard in the three cabins and move between bays at your own pace. There is snorkeling, paddleboarding and fishing along the way. Captain, crew, guide, insurance, snacks, drinks, fruit and equipment are included. Meals and park fees are extra.
