This exquisite ship, tastefully furnished with a generous deck space, intimate cabins, and a state-of-the-art kitchen, is securely moored on the paradisiac island of Koh Samui. The Catamaran Scarlet is designed for comfort, effortlessly accommodating up to 20 passengers, making it the perfect vessel for cherished family vacations or intimate group retreats.

Whether you're a family with children or a vibrant adult seeking fun, our sunset, half-day or full-day cruises are packed with a plethora of thrilling activities for everyone. Wave goodbye to monotony and welcome a sea of exhilarating experiences with swimming, jumping, kayaking, paddle boarding, sliding (up to 4 hours), and fishing.

The Catamaran Scarlet offers an array of cruises to suit diverse interests and timelines:

  • Sunset Cruises to Koh Som: Set sail north of Samui and savor a tranquil evening voyage framed by the breathtaking spectacle of a vibrant sunset.

  • Full-day Cruises to Koh Phangan: When time is on your side, immerse yourself in the awe-inspiring natural beauty of Koh Phangan.

Kindly note, due to the catamaran's cruising speed, day tours to Angthong, Koh Tao, or Koh Tan/Koh Madsum are not feasible as these destinations are a considerable distance from Samui.

We are committed to providing you with an effortless and pleasurable experience. To this end, all our trips come with an array of complimentary amenities. These include Vi transfers to and from the catamaran, an assortment of revitalizing soft drinks and snacks, a grill stove for those with a penchant for a DIY barbecue picnic, snorkeling gear for underwater discoveries, and a Bluetooth speaker to create an ambiance with your chosen soundtrack. Seafood BBQ or Thai lunch options can also be arranged upon request.

Embark on the Catamaran Scarlet for a magical seafaring journey where every trip is a promise of an enthralling and unforgettable experience that you will treasure forever!

Good to know

  • For guests requesting pickup from Koh Phangan, an 8-hour charter is the only option, as the boat takes approximately 1 hour each way from Samui. The cruise itself is about 6 hours, with no sunset option, as the boat must return before sunset.

Full-Day Morning 6 hours Koh Phangan

Overview

Spend a relaxed morning and early afternoon sailing from Koh Samui to the green, jungle-covered coast of Koh Phangan aboard the private sailing catamaran Scarlet. This 6-hour cruise runs from 09:00 to 15:00. It gives you enough time to enjoy a long sail, unhurried swim stops and a proper Thai lunch on board, and you are back on shore by mid-afternoon.

The whole boat is yours, with up to 8 guests on this itinerary, so you set the pace. Swim off the stern, jump from the deck, paddle a board along the shoreline, try the slide, drop a line for some fishing, or put on a mask and snorkel over the reefs. The crew handles the sailing and the lunch, and the grill is on hand if you want to cook your own picnic.

Why choose this cruise

  • Private charter for your own group, with up to 8 guests
  • Cool, calm morning sailing and the best light for swimming and snorkeling
  • Thai lunch on board and a back-to-shore time that leaves your afternoon free
  • Slide, paddle boards, fishing gear, snorkeling gear and Bluetooth speaker all on board

Note: because of the catamaran's cruising speed, this cruise covers the Samui and Koh Phangan area only. Angthong, Koh Tao and Koh Tan/Koh Madsum are too far for a day trip.

Overview

This 6-hour private cruise (12:30 to 18:30) starts at midday, sails to Koh Phangan, and ends with an evening sail back to Koh Samui in golden light.

What makes it special

  • Private charter for up to 8 guests, on your own schedule
  • Swim stops in the warm afternoon, with the sunset sail to finish
  • Thai lunch on board, so you do not need to plan a meal beforehand
  • A late arrival, so you can have a lie-in and still get a full day on the water

Note: day trips to Angthong, Koh Tao or Koh Tan/Koh Madsum are not possible on the catamaran because of the distance.

Full-Day with sunset 8 hours Koh Phangan

Overview

The 8-hour private cruise (10:30 to 18:30) is the longest and most complete day on Scarlet. It gives you time to sail to Koh Phangan, explore more than one swimming spot, eat lunch without rushing, and finish with the sunset as the catamaran returns to Koh Samui.

The longer schedule suits families with children and groups who want a slow, easy day. There is a long window for swimming, snorkeling, kayaking, paddle boarding, the slide and fishing, and still plenty of time to lie on the deck and do nothing. Lunch is a Thai meal served on board. If you feel like cooking, the grill is available as well.

Highlights of the day

  • Up to 8 guests, with the whole boat and crew to yourselves
  • The longest time on the water of any cruise, so no rushing between stops
  • Thai lunch on board and plenty of time for water activities
  • An evening sail back to Samui in sunset light

Note: because of the catamaran's cruising speed, Angthong, Koh Tao and Koh Tan/Koh Madsum cannot be done as a day trip. The itinerary stays in the waters around Samui and Koh Phangan.

Sunset

Overview

This 2.5-hour private sunset cruise (16:00 to 18:30) is the shortest way to enjoy Scarlet. It suits guests who want an evening on the water without committing to a full day. The catamaran leaves Koh Samui in the late afternoon, once the midday heat has passed. It sails along the north coast of the island to Koh Som, a quiet spot with calm, clear water.

After anchoring, you have time to swim, snorkel, paddle board, kayak, jump from the deck or drop a fishing line. Then the crew raises the sails and you head back towards Samui as the sky turns orange, pink and gold. The whole boat is yours, so you can set the mood. Put on your own playlist through the Bluetooth speaker, cook on the grill if you bring your own food, or lie on the trampolines with a cold drink and watch the light change.

What makes this cruise special

  • Private charter for your own group, with the whole boat and crew to yourselves
  • Short, gentle sailing distance to Koh Som, so most of the time is spent at anchor and at sunset
  • Calm evening conditions that suit couples, friends and families with children
  • A sunset sail back to Samui, with time to take photos from the deck

Dinner is not included. A Thai meal or seafood BBQ can be arranged on request, and you are welcome to bring your own food for the grill. Because of the catamaran's cruising speed, this cruise stays in the waters north of Samui.
