SeaTrek Sailing Adventures

The exotic tropical islands between Bali and New Guinea are the domain of SeaTrek Sailing Adventures, which specializes in authentic sailing adventures in traditional Indonesian pinisi boats.

From its home port in Bali, SeaTrek runs voyages of anywhere from seven to 12 days across the eastern half of Indonesia. Itineraries offer plenty of land and sea activities, as well as close encounters with the archipelago’s amazing scenery, wildlife and diverse human cultures.

Among the many ports of call are legendary places like Bali, Lombok, Sumbawa, Komodo, Flores, Raja Ampat, Ternate, Ambon and the Banda Islands.

For those who crave more, SeaTrek also offers special Expert Led cruises that let passengers delve deeper into disciplines like culture, history, literature, cuisine, natural history, botany and zoology.

Offering all the creature comforts of the modern world, SeaTrek’s two wooden pinisi — Ombak Putih and Katharina — are progeny of a centuries-old maritime tradition of handcrafted boatbuilding in Indonesia.

Constructed by the highly-skilled seafaring peoples of Borneo and Sulawesi — using hand tools and traditional methods — the design of these gaff-rigged ketches has been passed down from father to son for centuries.

Both vessels are outfitted with state-of-the-art safety equipment and communications technology, and equipped with tenders, kayaks, paddleboards and snorkeling gear.

All passenger cabins feature 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.

When not in service on fixed itineraries, the Ombak Putih and Katharina are available for charter for private holidays, special interest groups and professional organizations. SeaTrek offers many options for charter cruising along existing itineraries or brand new programs to suit individual needs.

Katharina SeaTrek Sailing Adventures


Led by Captain Iwan and operated by a crew of 12, the 40-metre Katharina sits low in the water, making her a most beautiful looking boat. Built in 1995 in Kalimantan, her slim hull was originally planned for use as a commercial freighter before she caught our eye with her simple lines and sleek structure. After her 2014 interior refit, her transformation is a conservation exercise back to authenticity of a mighty seafaring tradition. Not only is the Katharina very elegant on the water, she is also fast becoming a classic yacht, as very few of these original designs remain. Accommodating just 12 guests in six cabins, with a salon & bar, two sun decks, and an outdoor dining area, she offers a more intimate experience.

Ombak Putih SeaTrek Sailing Adventures

Ombak Putih

Led by Captain Agung, with a crew of 14, Ombak Putih means ‘White Wave’ in the Indonesian language. Her keel was first laid down in Kalimantan in 1995, and she became operational in 1997. At 42 metres long, she is the larger of our two ships, providing accommodation for up to 24 guests in 12 comfortable cabins. Approximately 400 square metres of public space is divided over her two main decks, including a large salon, as well as covered and open areas, allowing plenty of room for our guests to spread out, relax, and enjoy as much company or solitude as they wish.

Dances, Dragons & Magical Lakes I & II Ports of Call: Bali, Lombok, Sumbawa, Komodo, Flores

Dances, Dragons & Magical Lakes I & II

Immerse yourself in the Komodo National Park and Indonesia’s Lesser Sunda Islands from an intimate perspective, cruising through a panorama of islands and encountering new wonders on a daily basis. This adventurous, eight-day inclusive voyage of discovery aboard the 24-passenger Ombak Putih or the 12-passenger Katharina offers a cross-section of remote beaches, quiet coastal villages, jungle-clad mountain ranges, towering volcanoes, rivers, waterfalls, tribal rituals, a mysterious lake, and the legendary Komodo Dragons. As always, there will be ample opportunity to snorkel and view the kaleidoscopic beauty of the underwater world. Unlimited use of the stand-up paddle boards and sea kayaks on board will add yet another dimension to your nature explorations.

Orangutans & Dragons Ports of Call: Palangkaraya, Bali, Lombok, Sumbawa, Komodo

Orangutans & Dragons

For this exciting 12-day adventure, SeaTrek Sailing Adventures offers a heady and rare mix of encounters with orangutans, proboscis monkeys, tropical birds, Komodo dragons and manta rays, spectacular marine life and a chance to meet and experience the fascinating culture of the famed Dayak people of Borneo, with a river cruise up the Kayahan River of Central Borneo combined with sea voyage on a traditional pinisi schooner through the turquoise waters of the Komodo National Park and Indonesia’s Lesser Sunda Islands. Cruising by air-conditioned riverboat along Kalimantan’s meandering rivers remains the best way to travel through the hinterland of Borneo, with its wealth of ecological and cultural treasures that survive deep within the rainforest. Followed by a sea cruise on a traditional pinisi boat through the myriad islands of East Nusa Tenggara (as the region east of Bali is known) you will get to see up close the legendary Komodo Dragons, stopping at remote beaches, quiet coastal villages, waterfalls, a mysterious volcanic lake, and have ample opportunity for kayaking, paddle boarding, snorkelling and swimming along the way. This truly is a trip to excite all the senses and tick so many boxes – not least the mighty man of the forest, the orangutan.
