Embarking on a charter cruise with SeaTrek in the intimate company of family and friends will take you on a journey of authentic, simple pleasures, with five-star creature comforts and leisure pursuits, and all surrounded by the wide expanse and mystery of the tropical seas and islands of the East Indies.


We offer myriad options to those looking for customised cruising opportunities of any description: whether it a simple holiday with family and friends, or for special interest groups or professional organisations, all of our cruises can be adapted to accommodate any requirements or to highlight specific aspects of the vast Indonesian Archipelago. Tailored to your specific needs, with professional guides and crew dedicated to creating unforgettable experience of outstanding service and comfort, guests are free to indulge in a world of adventure and excitement, of natural beauty, of barefoot elegance and relaxing simplicity, all wrapped up in the pleasures if great accommodation, fine food, breath taking scenery and the pleasure of being enveloped by the endless horizon of the sea.


We have hosted charter guests from all walks of life looking for pleasure, adventure and that something different: snorkelling, adventure, bird watching, yoga, team building, photography, spice trade tours, cultural tours, naturalist tours, culinary tours, water sports, colonial history, TV & media, scientific research, or simply taking a relaxing cruise through the islands under a hot tropical sun on a sleek and beautiful sailing vessel, you call the shots.

We cruise across the archipelago all the way from Borneo to Papua in the west and east and Sumba and Maluko in the south and north, following the seasons and the winds, and staying one step ahead of the rains so as to provide optimum cruising conditions for our guests.

January to March: Raja Ampat, Sorong, Misool, Ternate, Kendari
April to September: Bali and the Lesser Sunda Islands including the Komodo Archipelago, Alor and Sumba
October to November: The Lesser Sunda Islands, Banda, Ternate and Rajat Ampat
December: Papua including Raja Ampat and Triton Bay

We would like to welcome aboard the MV Katharina, our traditional 35-metre, pinisi style, wooden schooner, to show you how we can create for you and all inclusive, personalised and unforgettable journey across the seas and islands of Indonesia, one of the last great frontiers of maritime adventure. Unlike a large cruise ship, Katharina has only six cabins, with a maximum capacity of 12 adults and 2 children, giving you the freedom to do what you want and when you want to do it. Recently redesigned and constructed of natural woods and classic décor, our stylish cabins are bright and inviting with double or twin berths, individually controlled AC and en-suite bathrooms.

Our 12-cabin Ombak Putih is also available for charters, but since her schedule is very full with our regular by-the-cabin cruises, these must be arranged a very long time in advance, thus allowing us to include it in our schedule. Occasionally she does become available when an unexpected cancellation occurs thus opening her up for charter. Please email us with your enquiry.

Our vessels have first rate, multilingual tour guides and are crewed by highly trained stewards and sailors, all of whom are dedicated to creating an unforgettable experience. However, if you would like specialists such as a personal chef, a yoga or free diving instructor, simply let us know.

We like to provide our guests with a full and final price for their charter bookings, free from hidden costs and with as few supplements as possible. These are based on a 24-hour day with six hours of cruising a day, full board with professional tour leaders and crew, all food and beverage (except alcohol), park fees, water sports and all taxes an service charges except tips for our crew. Tariffs vary accordingly in cruising areas due to the substantially larger costs of operating in eastern Indonesia.

Central Indonesia – Bali / Komodo / Sulawesi / Flores - US$5,400 / day
Eastern Indonesia – Raja Ampat / Maluku / Papua US$7,200 per day

We have ample on-board facilities and activities to help you and your guests unwind and get the most out of this tropical playground, including snorkelling, swimming, kayaking, fishing, paddle boarding, or simply lazing in the sun with a good book. For specialised pursuits we are happy to arrange for any kind of activities such as cooking classes, free-diving, rock climbing, kite surfing, wake boarding, etc. Simply ask and we will do our level best to accommodate any wishes.

We understand that the cost of chartering one of our boats is high and that is why we are happy to create realistic payment plans to keep it as simple as possible. Just ask us for details.

If you don't have the numbers to fill a boat just let us know and we will try our hardest to help out by using our connections and international networks.

We do charge for beer, wines and spirits but at a very low cost so as not to break the bank. Guests are welcome to bring their own alcohol on board at no extra cost. Clients must cover flights to and from embarkation points and extra fuel surcharge may apply if clients wish to include multiple areas or long journeys that require a major repositioning of the boat.

Our boats are the ideal family environment and we are happy to accommodate children of all ages.

Ian Burnet

This itinerary will be enhanced by descriptions and presentations by the Australian author Ian Burnet who has spent 30 years living, working and travelling in Indonesia, and is fascinated by the diverse history and cultures of the archipelago. His first book, ‘Spice Islands,’ tells the 2000-year-history of the spice trade from the Moluccas of Eastern Indonesia through China, India and the Middle East until the spices reached Europe. It was the lure of the fabled Spice Islands and exotic spices such as clove and nutmeg that drove ‘The Age of Discovery’ and the first circumnavigation of our planet. Spice Islands has been described as “A wonderful book – a triumph of passion and scholarship.”

‘East Indies,’ Ian’s second book, begins in the port city of Malacca, and tells the story of the 200-year-struggle between the Portuguese Crown, the Dutch East India Company and the English East India Company for trade supremacy in the Eastern Seas. It follows the rise of the world’s first joint stock and multinational trading companies and their conversion to huge colonial states ruling over millions of people in Indonesia, India and Malaya. The book documents the founding of the historic port city of Batavia (Jakarta) and concludes with the founding of the modern port cities of Singapore and Hong Kong.

Dr. Tony Whitten

Dr. Tony Whitten was trained as a wildlife biologist and since late 2010 he has been the Regional Director for Asia-Pacific at Fauna & Flora International, the world’s oldest international conservation organization. The subject of his PhD at Cambridge University was on the endangered gibbon on a remote and primitive island west of Sumatra in the mid 1970s. After this Tony worked at the University of North Sumatra where he initiated production of a major and innovative series of books on the ecology of the several regions of Indonesia, writing three of them himself, each taking about three years. During a two-year spell in the UK, he was employed by the British government’s conservation agency to write its Recovery Plan for Protected Species – covering sea anemones to wild cats.  He joined the World Bank in 1995 and supported a broad range of activities and projects until he left in 2010: he advised on habitat and species protection issues as part of infrastructure projects, started various region-wide and global activities (e.g. on the forgotten biodiversity of caves and karst), ran a programme which produced 111 volumes of local language field guides to all manner of plants and animals, and was responsible for a suite of conservation projects in Mongolia, China, Indonesia, Lao PDR, Vietnam and elsewhere in the region.  He has an in-depth and broad knowledge of biodiversity and has published on a wide variety of topics.

Gert De Jong

In 1990, Gert de Jong lived in the Moluccas for six months as a student in marine biology studying dugongs and seagrass. He fell in love with the oceanic islands of eastern Indonesia and its people. He then worked as an ecology consultant in studies on marine mammals, and as a teacher of biology in Amsterdam. In 2008, he started a conservation project for the seabirds that were breeding on remote Indonesian islands. For pantropical seabirds, such as frigatebirds, there are only a few islands left of refuge on which they can breed in Southeast Asia. Since 2012 Gert has worked as an independent researcher studying swifts in Amsterdam during their breeding season, and now, in 2015, he is continuing the Indonesian seabird project, to study and protect the unique island habitats in the Flores and Banda Seas.

Formerly a blue-water mariner, celestial navigator and skipper, Jeffrey became a specialist marine writer and photographer and has made a lifetime study of the fascinating maritime world of Asia and in particular of Indonesia. He has published extensively on these subjects in both popular and academic journals. Jeffrey has been visiting Indonesia since 1975 when he was immediately drawn into the maritime life of this tropical archipelago with its extraordinarily diverse cultures and history – as well as the study of Bahasa Indonesia, a national language with its roots in the ancient world of sailors and seaborne traders. Jeffrey’s richly illustrated presentations on your SeaTrek cruise draw upon decades of research and adventures sailing with the traditional seafarers and boat builders of Indonesia. He has also sailed through the archipelago by yacht. Jeffrey has shared his knowledge and enthusiasm for this oceanic world by leading tour groups exploring maritime themes in Indonesia, Malaysia, Cambodia and India.
