Two-engine Speedboat "Rubi Grace"

Cruise across the Gulf of Thailand to Koh Tao and Koh Nangyuan on a private charter aboard Rubi Grace. Reaching speeds up to 37 knots, this 38ft sports cruiser offers swift passage to the region's premier snorkeling grounds, known for clear water and varied marine life.

The charter moors off Koh Nangyuan's sandbar, allowing time to snorkel the coral formations of Japanese Gardens or hike the wooden stair trail to the island viewpoint. Around Koh Tao, the route visits protected granite bays such as Shark Bay, Mango Bay, or Hin Wong Bay, selected according to daily sea conditions for sightings of sea turtles and reef fish.

Between snorkel stops, guests can rest in the shaded aft lounge, sunbathe on the forward bow daybed, or rinse off with the onboard freshwater shower.

Explore the coastline, hidden bays, and coral reefs of Koh Phangan on a private full-day charter aboard Rubi Grace. A private boat allows access to secluded northern and eastern beaches bordered by tropical rainforest and granite cliffs that are difficult to reach by road.

The route travels to Koh Ma and Mae Haad, where an offshore sandspit borders a shallow reef suitable for snorkeling. The cruise continues past coastal headlands to the sheltered cove of Bottle Beach (Haad Khuat) and the twin bays of Thong Nai Pan for swimming and a beachfront lunch break. In the afternoon, the boat stops at Than Sadet Bay, home to a historical freshwater stream and granite boulders, before tracing the southern coastline back to Samui.

Rubi Grace offers shaded cockpit seating, an open bow sunbed, an enclosed toilet, a freshwater deck shower, and a sound system for a self-paced island tour.

Take a private coastal tour of southern Koh Samui and its neighboring islands aboard Rubi Grace. This full-day charter visits the tranquil shallow reefs of Koh Tan and the sandy shores of Koh Madsum (Pig Island).

A short transit brings guests to Koh Madsum, where they can walk on the white-sand beach and observe the resident pigs that roam the shore. The cruise also navigates past the limestone outcrops of the Five Islands (Koh Si Koh Ha), known for swiftlet nesting caves, before stopping at quiet coves near Taling Ngam or Laem Sor for swimming.
