who we are

We are especially proud of our Expert Led cruise programme, which offers guests a more immersive opportunity to delve deeper in a range of disciplines that includes culture, history, literature, cuisine, natural history, botany and zoology whilst in the company of expert tour leaders, who are masters in their chosen fields.

Travelling with like-minded companions from all corners of the world contributes to convivial and spirited exchanges, enriching the entire experience, and we take pride in all the friendships which are born and blossom on our boats, both between guests, and between guests and our crews, whether for a moment or for a lifetime.
Our Ships
Offering all the creature comforts of the modern world, our two wooden pinisi ships, Ombak Putih and Katharina, are part of a beautiful, centuries-old maritime tradition of hand-crafted boatbuilding in Indonesia. Built by the highly-skilled seafaring peoples of Borneo and Sulawesi, using hand tools and traditional methods of construction, the design of these gaff-rigged ketches has been adapted and passed down from father to son for centuries. Interestingly, the pinisi fleet still forms the massive bulk of Indonesia’s cargo and transport network today.
Our boats are outfitted with the most up-to-date safety equipment and communications technology, and equipped with high-quality tenders, kayaks, stand-up-paddle boards and snorkelling gear. Our comfortable cabins are located below decks and offer all the necessary amenities, including double beds or twin bunks, private en-suite bathrooms, lots of natural light, individually controlled air-conditioning, ample storage space, and plenty of electrical and USB outlets.
In 2014 and 2015 respectively, working with the unique legacy these vessels represent, Katharina and Ombak Putih both had major refits. Their transformation was an exercise to conserve their authenticity, using only the best traditional materials, and shaped by highly skilled Indonesian craftsmen of the same heritage that built them.

Testimonial
“AMAZING! No lie, this was one of the best trips my husband and I have ever taken. No, it's not cheap, but worth every penny. We wanted celebrate our 25th wedding anniversary in a way we've never done, and this was the way to go!”
“We chartered the SV Katharina and crew for a family holiday in June 2023. It was the holiday of a lifetime. Everything was perfect. We are already looking forward to our next adventure with SeaTrek.”
“WOW WOW WOW! Seatrek's 9-day Whale Sharks, Corals & Dragons cruise will go down as one of the most memorable travel experiences of my life!”
“The meals were so diverse and every meal had multiple options for every kind of eater- pescatarian, vegetarian, and meat lovers! The food was always high in protein, nutritious, and had fresh, high quality ingredients.”
“We snorkeled in breathtaking coral reefs nearly every day, and even got to swim with Whale Sharks on Northern Sulawesi. Each day was an adventure!”
“The spectacular snorkelling was the best I have ever done. The boat was beautiful, and very comfortable. The local guides and crew were excellent. They catered for all capabilities and their care and thoughtfulness meant everyone was able to enjoy themselves.”
“SeaTrek is a marvellous company. Our guide, Anastasia, and the whole crew were wonderful. The experiences - the uniqueness of our tour - made this an extraordinary journey. I can't recommend them highly enough.”
“One can not overstate how wonderful and relaxing a vacation this was. Put this trip on the top of your bucket list.”
“This was an utterly fascinating, exciting, relaxing trip. The boat is beautiful, well kept and has everything you could need.. We actually slept on deck most nights. The breeze blows gently, very quiet throb of the motor, with beautiful sunrises. This was a trip of a lifetime, actually we are considering doing it again so maybe can't say its a trip of a lifetime as there may be many more.”
“Not only did we have the best snorkelling sites presented to us daily but the also opportunity to discover the birds, butterflies and Alfred Wallace, a contemporary of Darwin, through the excellent on board guides and the expert , Dr George Beccaloni, who accompanied us throughout. It was an excellent mix of interests not forgetting of course the information around the sea life that we were fortunate to see, including the oceanic giant manta ray!”
“I have travelled with these guys a number of times. The care and attention to detail they offer is second to none and having travelled on many cruise ships in my time both as a guest and a lecturer I have to say that SeaTrek blows them all away. We will be back out there in December and we cannot wait.”
“Raja Ampat Heaven!! I loved this trip so, so much! (Take me back....) What an amazing experience.... God, I hope I get a few more like that in my lifetime!”
