Thailand / Similan Islands

Koh Tachai is located at the northern tip of the Similan Islands National Park and the latest addition to the coverage of the National Park area along with Koh Bon. Koh Tachai boasts spectacular white beaches and crystal-clear waters surrounding it.

According to National Geographic Society Koh Tachai is due to its remoteness among the top 10 diving destinations in the world. On the island you can trek the nature trail to spot hermits, various reptiles, and Nicobar pigeons. This ancient jungle is full of wonders and mysterious wildlife that is hard to find elsewhere.

Incredible day on the water with a fantastic crew! From the first contact to the last wave, everything was perfectly organized. Steven handled all the details, from flexible booking to perfectly timed hotel transfers. The crew was professional, friendly, relaxed and so much fun. If you're looking for an exclusive and carefree catamaran experience in Thailand, this is the place to go. Would absolutely book again.

★★★★★

We booked the Jana 43ft sailing catamaran for a private day trip to Ang Thong Marine Park and it was truly the highlight of our stay in Koh Samui. The boat was spacious, clean, and very comfortable. The crew was fantastic — professional, friendly, and extremely accommodating. The views were breathtaking, and we enjoyed a delicious lunch on board. A special moment was on the way back — we caught a fish! Highly recommend this experience.

We had an amazing experience with the private yacht company today! We booked on very short notice for a group of 10, and everything exceeded our expectations. The three crew members were absolutely fantastic — friendly, professional, and made sure everyone was having a great time from start to finish. The food was delicious, the trip itself was unforgettable. Highly recommend!

We had a fantastic experience with private-yacht for our company vacation trip. Smooth experience from pickup to drop off. The yacht was spacious and comfortable, with shade and a sun-bathing area. There was a DJ on board. Steven and his team were very helpful throughout the whole trip. They helped us pick the appropriate yacht, gave recommendations and even helped with a short notice request for a photographer. Highly recommend!

★★★★★

The most amazing experience in Koh Samui. The booking was very easy through WhatsApp. The yacht is beautiful, plenty of space to sit. The food for dinner was delicious. We ended up with a few more people and they were flexible in arranging for that. Payment was secure through Wise. All staff was very friendly and helpful. Highly recommend this company for yacht trips.
