About Us

The Creator of wild and authentic tailored safaris in the Coral Triangle

About Us

Coral Triangle Safaris (CTS) was established in 2017 from a passion to explore Indonesia, the world’s largest archipelago with over 17,000 islands. With such a vast area to explore dotted with small islands, the ultimate mode of transportation is a private yacht. The launch of our highly sophisticated 26m (86’) vessel Sequoia raised the safety and quality standards within the private charter market in Indonesia. Our goal is to help you and your family experience one of the world’s most remote and beautiful places, The Coral Triangle, as safely and comfortably as possible.

Your Host-Yessi Sari

Yessi was born in a mountain town in South Sumatra, Indonesia and educated under a full scholarship at the School of Economics, University of Indonesia. After graduating with a CPA degree, she was recruited by Johnson and Johnson. She transitioned into a marketing role working for Unilever and L’Oreal.

She decided to change course and follow her passion, traveling the world from The Himalayas to Raja Ampat. Yessi came to realize that the ultimate travel destination was at her doorstep, the Coral Triangle within The Indonesian Archipelago. This led her to found Coral Triangle Safaris to facilitate safe and comfortable travel to the richest reefs on earth.

She built Sequoia which is the newest generation of Indonesian classic wooden yachts available for charter in Indonesian waters. She will also be on board Sequoia as the Cruise Director to ensure that the customer experiences the safest and most enjoyable cruise possible.

What makes us different?

There are many things that distinguish us from our competitors. Indonesia is a land of incredible diversity with over 300 tribes speaking 700 languages. Being the only luxury yacht with an educated and passionate Indonesian owner as well as a cruise director will help you to understand Indonesia and our culture well beyond just dive sites and volcanoes. We employ an all-local staff and ensure fair prices and wages to our people, community, and trade partners, which are critical to our mission. We celebrate the beauty of our diverse population just a much as our natural resources both above and below the water.

We are also conscious to make sure that our carbon footprint is minimized. As we explore this fragile ecosystem we need to keep mindful that it needs to last forever. We have selected and sourced our products with this in mind including the latest low-emission engines and electrical generator systems available in the US. We built Sequoia using US Coast Guard Safety Standards as our guideline. We practice a “no one time plastic use” policy with things such as straws, water bottles, utensils, and other plastic on board Sequoia. This includes palm free bath products.

Unlike other charter companies, we offer an “All Inclusive” price meaning all your customized food, spirits, wine, water and land excursions including PADI dive certification up to advanced open water, dive gear, taxes, park fees are included in your initial payment and there are no “add on” extra charges at the end of your Safari. Tipping is not included and is at the discretion of the client.


She is a vessel of delight, a celebration of extraordinary vision, determination and skills in hospitality.
