Sailing Indonesia: Rare Routes
Experience Indonesia's undiscovered frontier aboard the 24-guest Ombak Putih or 12-guest Katharina. Meet remote island cultures, seek out exotic birdlife, snorkel in pristine coral reef and explore some of the least visited parts of the Indonesian archipelago along Sulawesi and the Maluku Islands.
Explore beyond the reaches of popular port towns to see a more authentic, undiscovered Indonesia. These remote itineraries go where few passenger ships do, and reap the rewards of their custom yet flexible itineraries and excellent local guides leading the way.
Choose from routes that cruise Sulawesi, the Maluku Islands, the Spice Islands, Raja Ampat and the stretches in between. These are truly the most remote and least-visited parts of the Indonesian archipelago. And a highlight is passage aboard the 24-guest Ombak Putih or 12-guest Katharina. These traditional pinisi-style ships are AdventureSmith favorites for private charter cruises due to their romance, Indonesian culture, rustic charm and superior service. Complimentary onboard snorkeling equipment, kayaks, stand-up paddleboards, fishing gear and tender boats equip guests with daily adventures on every route. Learn a bit more about each one:
On the main 14-day itinerary, travel from the spice port of Ternate to the shipbuilding port of Bitung in North Sulawesi while sailing through the islands that fringe the Molucca Sea. Numerous highlights include remote island cultures, Bajau sea gypsies, birds of paradise and other exotic birdlife, volcanic peaks and ample opportunity for snorkeling on fantastic coral reefs and in lakes filled with freshwater stingless jellyfish. Experience Halmahera, the island where famed naturalist Alfred Russel Wallace developed the idea of natural selection via survival of the fittest, then wrote and sent it on to Charles Darwin.
On the alternative 16-day Corals, Cultures & Dragons sail the length of Sulawesi from Bitung Harbor down to Flores Island. The journey is the reward here as you cruise along and meet fishermen and villagers who only see your ship once every few years. While you won’t have the chance see birds of paradise or Halmahera on this route, you’ll trek to see the rare maleo bird, snorkel with sea turtles and seek out black-crested macaques, with the grand finale of seeing Komodo dragons in Komodo National Park. Another similar southbound route sails from Ternate in the Spice Islands to Flores, also over 16 days with Komodo National Park a final stop.
On the alternative 12-day To the Scents of the Spice Islands itinerary, navigate the Banda Islands and much of the famed region as you sail northbound from Ambon to Ternate. Go in search of famed naturalist Alfred Russel Wallace and his living treasures, taking in firsthand experiences of unique ecology and visiting some of the places that most fascinated Wallace: Ambon, the former capital of the Moluccas; Bacan, where Wallace made some of his greatest zoological discoveries (birds of paradise, the world’s largest bee); Ternate, Wallace’s base for his eastern travels and once the center of the world clove trade; and the mysterious island of Halmahera where Wallace discovered evolution by natural selection.
On select alternative itineraries between Ternate and Sorong, also visit the remote Raja Ampat Islands with their pristine, incredibly diverse coral reefs and up to five species of birds of paradise. Many of these sailings feature special guest hosts who are experts in endangered species and evolutionary biology. Or opt for an East Indies Spice Exploration route cruises from Flores to Ambon, exploring more of the Lesser Sundas than other Spice Islands cruise routes. Each itinerary offers a unique slice of history, along with incredible snorkeling, kayaking and trekking.

Rare Species, Remote Cultures & Remarkable Corals: Ternate to Bitung Itinerary
The main, 14-day Rare Species, Remote Cultures & Remarkable Corals: Ternate to Bitung cruise sails clockwise around the Molucca Sea, from the spice port of Ternate in North Maluku, south along Halmahera, east to Central Sulawesi and north to the shipbuilding port of Bitung in North Sulawesi. In this, one of the least visited parts of the Indonesian archipelago, opportunities abound to spot exotic birdlife, explore colorful coral reef and interact with communities housed both on land and sea.
Start the adventure with a tour of Ternate’s historical highlights before boarding the ship, meeting the crew and settling into your new home for the next two weeks. Over lunch, the ship sets sail for the short journey to Halmahera Island’s Dodinga Village, a pivotal place in scientific history, where the naturalist Alfred Russel Wallace first came up with the Theory of Evolution by Natural Selection.
Today visit the Guraici Archipelago, a chain of islands with white sandy beaches, vibrant coral reefs and some lovely local villages. Spend a full day here snorkeling, swimming and pay a visit to one of the villages to meet the local people. The islands are part of a government-controlled conservation area, designed to protect the reefs and the many beautiful marine species that live there. It may also be possible to see manta rays here, and these protected waters also provide the perfect location for beginner or rusty snorkelers to become familiar with the water and to hone their skills for the many days of snorkeling that lie ahead.
Explore the deep forest and rivers of Bacan Island, where Wallace first saw what he called ‘the most beautiful butterfly in the world, the Golden Birdwing. During your trek, the other species that yo might see here include cuscus, hornbills, and other birds, and maybe even an encounter with the black-crested macaque.
Snorkel on some spectacular coral reefs and visit a local hot spring where you’re encouraged to take a warm dip.
Visit Belang Belang Island, which offers fantastic snorkeling both on the reefs and the mangroves, which act as a nursery to many marine species, including baby sharks and many kinds of school fish. Explore the huge inland lagoon, which you can explore from the boat tender. The island is home to healthy populations of birds, including parrots, tree swifts, imperial pigeons and many more.
Today will be a day for snorkeling, culture and history in the middle of the Banda Sea, in the remote and breathtaking Sulu Archipelago. Spend the morning exploring the beaches and reefs of Mangoli Island, where the reefs are teeming with fish and other marine life. True to the desert island locale, enjoy a kayak, paddle or swim, and explore and relax on the white-sand beaches.
Visit a local village market and see the ruins of a 17th-century Dutch fort, which once protected the spice trade along these routes. Be treated to a traditional dance known as the ‘cakalale’, by local warriors. You will also have a chance to explore the local village and meet the people of this remote region.
Enjoy a beach BBQ, and be regaled with traditional Indonesian folk songs and sea shanties as you party by firelight late into the night.
The Bokan Islands are an area of unsurpassed beauty and today is a day of marine exploration and relaxation. Snorkel, swim, paddle and kayak around the glorious reefs, beaches and islands that offer many caves and snorkeling spots. Enjoy the rare privilege to swim in a small marine lake filled with stingless jellyfish, the exotically named Danau Piasu Botangan, one of only 20 lakes of its kind in the world.
Visit the bustling Indonesian island port town of Banggai, where you will visit the local market, the sultan’s palace and the Maleo bird egg ‘museum’, and all from a fleet of brightly-colored motor rickshaws, which will be on the dock awaiting your arrival.
Pay a hands-on visit to LINI, an NGO doing great work with coral restoration on the surrounding reefs, in addition to working with local fishermen in finding sustainable solutions for supplying fish for overseas markets and the live aquarium fishing trade.
Today brings the chance to see possibly one of the strangest and most unique flightless birds found in the world–the Maleo. Visit a conservation project on the mainland where scores of Maleo live and breed. Watch them at their sandy nesting sites from a camouflaged hide as they go about their business.
Visit the Togean Islands National Park for some island hopping and spectacular snorkeling, wildlife and culture. Today will be your first encounter with the Bajau sea gypsies of Southeast Asia and their famous patriarch ‘Jago’, a people with a unique way of living with the sea. About 2,500 people live in this small village, and you will be welcomed into their world to meet and talk with them about their lives.
Some great wildlife experiences await both in the water and the air, with birds, fish, Babirusa (Indonesia’s rare native pig), and invertebrates as the main features. Enjoy a snorkel on the lush reefs near the island of Malenge, before taking your snorkel and mask for a rare second swim with stingless jellyfish.
Visit a local village and meet the people, and enjoy a late afternoon walk in the forest before being witness to a most amazing show of nature as flocks of hornbills come flying in to roost in the trees–a once-in-a-lifetime sight only accessible via your ship.
.
After an overnight crossing from Togean, start the day with an early morning swim with whale sharks that congregate just off the coast at a small village in North Sulawesi. Swimming with these gentle giants is one of life’s highlights and is not to be missed.
Visit Tangkoko National Park for a trek through the forest, a haven for many rare and endemic wildlife species, including spectral tarsiers, black-crested macaque, cuscus and a wide variety of birds. This is where Wallace did a lot of his collecting, and you will visit a statue that celebrates this great man.
After a final swim and snorkel on the beach and then a short sail into Bitung Harbor, say a fond farewell to your crew and tour leaders and head to Manado City for your onward flights.

Katharina is a 12-guest sailing vessel whose adventures explore the Ring of Fire, the string of volcanic islands that stretch out from Bali east to the Philippines. Katharina is a mix of traditional and modern design. Her hull and rigging are traditional, while the deck house and interior are custom designed to cater to Western tastes of space, privacy and comfort. While Indonesian traditional sailing vessels are customarily referred to as Bugi schooners, strictly speaking, Katharina is rigged as a ketch, the foremast being higher than the aft mast.
Why Sail Aboard Katharina
Choose this ship to sail aboard a modern vessel with rich cultural roots and a remarkable history of transformation. Katharina is a gorgeous sailing vessel that AdventureSmith Explorations is proud to represent among our many small ship cruises around the world. The founder of SeaTrek Sailing Adventures discovered her under construction in 1998 while he was paying a courtesy visit to some old Buginese friends who had moved to Batulicin. He spotted her slender hull under construction on the riverbank and made a deal with her builder, based on the Buginese principle that all boats are always for sale even before they are launched. This story, of how Katharina was rescued from a hard life of carrying cargo, is now an important chapter in the history of SeaTrek Sailing Adventures. She was baptized Katharina, and a French naval architect redesigned the superstructure and the interior of the hold.
AdventureSmith Explorations has been aboard the Katharina. Read our dedicated Katharina Ship Review, written by two of our specialists, for our firsthand take on life aboard. Or consult this page further for a detailed description of Katharina, including ship specs, deck plan, cabin images, a photo gallery and current links to all the trips she sails. Our team can help you compare the Katharina with other small cruise ships and yachts offering Indonesia cruises, Pacific Island cruises and Asia cruises, including private charter cruises.
History Aboard Katharina
The founder of SeaTrek Sailing Adventures discovered her under construction in 1998 while he was paying a courtesy visit to some old Buginese friends who had moved to Batulicin. He spotted her slender hull under construction on the riverbank and made a deal with her builder, based on the Buginese principle that all boats are always for sale even before they are launched. This story, of how Katharina was rescued from a hard life of carrying cargo, is now an important chapter in the history of SeaTrek Sailing Adventures. She was baptized Katharina, and a French naval architect redesigned the superstructure and the interior of the hold.
Katharina Design
The Bugis people of south Sulawesi, once feared as pirates, are known as the most skillful ship builders and sailors of Indonesia. Their vessels, perahu (smaller fishing boats) and pinisi (cargo carriers, like Katharina was intended to be), were and still are hand-crafted entirely from timber. The pinisi are elegant two-masted schooners with mainsails, top-sails and three jibs. Today, while still hand-built by native craftsmen from tropical hardwood and still with traditional rigging, they usually hold an engine in addition to the sails. The construction of of a pinisi hull always follows age-old and well-established design principles. What is most remarkable is that these huge handmade structures (in the case of Katharina, a total weight of 300 tons of wood) are made without any drawings, fully relying on the intuitive craftsmanship of its builders as passed along through many generations. Contrary to Western boat-building practice, the Bugis method of hull construction is to start with the planking and fit in the beams later.
Katharina is different from most traditional pinisis because she became a joint effort between western naval architects and traditional Bugis skills. The superstructure and the interior were redesigned to accommodate small groups of passengers for cruising in the Indonesian archipelago, offering an excellent standard of reliability, safety and comfort. Her spacious air-conditioned, en-suite staterooms, the dining/recreational area and the large deck space with comfortable chairs and sun beds make the Katharina perfectly suitable for extended passages and leisure cruises.
Common Areas Aboard Katharina
The deck area of Katharina is dominated by the 82-foot-tall main and top masts and a large central table around which you can enjoy meals alfresco. Just aft is the main lounge and bar, accessible on the port side and featuring a television, DVD player and music center. Note that WiFi is not available, however local SIM cards can provide intermittent internet access via your personal phone. On top of this main cabin there is a sun deck with deck chairs and comfortable day beds. Guests enjoy unlimited use of snorkeling equipment and two sea canoes. Katharina does not carry binoculars, so guests are recommended to bring their own. Redesigned in 2014, the salon and central dining areas now feature an upper deck shaded lounge.
Dining Aboard Katharina
Free tea, coffee, soft drinks, juices and mineral water is available on board Katharina, as are excellent meals and snacks. You'll enjoy a welcome drink and chilled towels to refresh you upon embarkation. Vegetarian diets can be accommodated upon request. Wine, beer and other alcholic drinks are available for purchase on board; however, Indonesia has high import taxes for alcohol, so guests are permitted to bring their own wine or liquor, which should be stored in staterooms as there is limited space in the ship's coolers.
Safety & Sustainability Aboard Katharina
Katharina is fitted with all internationally required safety and communication equipment such as SSB and VHF radios, life jackets, life rafts and satellite telephone. Her crew is a well-trained, well-seasoned Indonesian crew of 13, several of whom have worked on the vessel since she was launched. Much attention is given to her maintenance; she has an annual docking period and periodical checks of all the technical installations on board. In 2014, Katharina received a complete overhaul of all auxiliary systems and was equipped with solar panels, wind generators and deep cycle marine battery systems so she would have the smallest possible carbon imprint.
Cabins & Deck Plan Aboard Katharina
The staterooms were completely redesigned in 2014, including natural light and a new state-of-the-art air conditioning system. Each stateroom aboard Katharina has a wardrobe, a built-in mini safe, individually controlled cooling systems and soft lightning. All staterooms have their own private bathroom with (warm & cold water) shower, wash basin, toilet and toiletries. Towels and beach towels are regularly changed. There is ample space to store your belongings and still move about with ease. And an added bonus is mattresses and light blankets available on the Top Deck for sleeping under the stars, an unforgettable experience that a cruise in the tropics affords. Voltage on board is 220 volts. In each cabin there is a socket suitable for 2-way European plugs. Two triple cabins offer a third bunk suitable for a child, increasing the guest count to 14 by request.
The 24-guest sailing vessel Ombak Putih combines traditional and modern design to bring authenticity and comfort to her itineraries in the Ring of Fire region stretching through Indonesia. This intimate vessel is a gaff-rigged ketch just oozing with Indonesian charm and an Old World sense of simple luxury. As a traditional pinisi-style ship she was built in the sturdy and efficient way that ironwood ships have been built for hundreds of years on the islands surrounding Sulawesi. She is well fit for her memory-making itineraries and her beauty as the perfect match for the stunning region and waters in which she plies. The Ombak Putih, means “white wave” in Bahasa Indonesia and is quite the appropriate ship for traveling from idyllic island to idyllic island throughout the remote intrigue of Indonesia.
Why Sail Aboard Ombak Putih
Choose the Ombak Putih for an intimate sailing adventure on a sustainably-minded traditional ship with an Indonesian crew. This ship is romantic for couples, family-friendly and ideal for a group of friends. Travelers are sure to be impressed by this ship's all-wood interiors, lending your voyage a feel that harkens back to the time of spice trade. Ombak Putih is fitted with all internationally required safety and communication equipment such as SSB and VHF radios, life jackets, life rafts and satellite telephone. Other safety measures include the reliable "work horse" Detroit Diesel engine, anchor chains instead of wire rope and many safety features demanded by the Australian coast guard for ocean-going vessels. Her crew is a well-trained, seasoned Indonesian crew of 16, several of whom have worked on the vessel since she was launched, complemented by a multilingual cruise director.
AdventureSmith Explorations has been aboard the Ombak Putih. Read our dedicated Ombak Putih Ship Review, written by two of our specialists, for our firsthand take on life aboard. Or consult this page further for a detailed description of Ombak Putih, including ship specs, deck plan, cabin images, a photo gallery and current links to all the trips she sails. Our team can help you compare the Ombak Putih with other small cruise ships and yachts offering Indonesia cruises, Pacific Island cruises and Asia cruises, including private charter cruises.
History of Ombak Putih
Ombak Putih's construction followed age-old and well-established design principles. Throughout Asia, the Buginese people from the island of Sulawesi are well-known for their shipbuilding skills; most remarkable about Ombak Putih is that this huge handmade wooden structure was made without any drawings, fully relying on the intuitive craftsmanship of its builders as passed along through many generations. A Dutch naval architect was hired to recalculate and verify all dimensions for ultimate seaworthiness, as well as design the interior and the deck house. Only first-quality ironwood timber was used, making the hull considerably thicker than most other wooden vessels (ranging from 10cm down below to 6cm near the deck). Construction on Ombak Putih began in May of 1996.
One year after construction started, six men started digging. In Batulicin, boats are not towed into the water. Instead, men dig away the soil underneath, thus creating a small canal out of which the boat is eventually pulled. On May 27, 1997, the Ombak Putih was launched, complete with the Buginese tradition of a goat being ritually sacrificed and its blood scattered over various important places of the ship.
Common Areas Aboard Ombak Putih
The charming, classy and clean Ombak Putih offers a variety of common spaces for all passengers to find a nook. The spacious enclosed salon has room to relax and read and includes the ship's library, presentation TV, small bar, coffee station, the electronic charging "dry zone" and mini-fridge. A charming outdoor dining and seating area on the main deck is where all meals are served (completely covered in canvas to protect from sun and rain) and offer plenty of room for viewing wildlife and wild seascapes from the rail. Ombak Putih does not carry binoculars, so guests are recommended to bring their own. The bow offers cushioned seating for six to watch the sunset and to lookout for dolphins. On the Top Deck, an uncovered bow facing area and the covered viewing area aft of the wheelhouse provide an ample supply of benches, loungers, couches and even bean bag chairs for reading, napping, journaling, socializing with shipmates or simply watching the jaw-dropping landscapes of Indonesia slip by.
Dining Aboard Ombak Putih
Free tea, coffee, soft drinks, juices, filtered water (reusable water bottle is provided) and mineral water is available on board Ombak Putih, as are excellent buffet meals and snacks. Enjoy a welcome drink and chilled towels to refresh your embarkation. Vegetarian diets can be accommodated upon request. Wine, beer and other alcoholic drinks are available for purchase on board; however, Indonesia has high import taxes for alcohol, so guests are permitted to bring their own wine or liquor, which should be stored in staterooms as there is limited space in the ship's coolers.
Meals are served in large dishes, buffet or family-style, with guests being able to select their own portions. Breakfast includes several cereal, granola and bread options alongside a changing menu of Western- and Eastern-style cuisine. Eggs and a small menu of choices are made to order upon request. Crackers, cookies and nuts are available self-serve any time of day, and the chef prepares an early evening traditional snack before each night’s dinner. Dinners include steak and seafood, soups and always a refreshing salad. Dessert is served plated at both lunch and dinner, and is most often an assorted tropical fruit plate punctuated by a few custards and cakes throughout the voyage.
Activities Aboard Ombak Putih
Take advantage of the marine life by using complimentary onboard snorkeling equipment, kayaks, stand-up paddleboards, fishing gear and two tender boats. Beach towels and sarongs are provided and there is a freshwater on-deck shower for rinsing off after activities. Scuba diving may be arranged on select itineraries at an added cost. The 2:1 guest to guide ratio ensure guests are completely taken care of during any activity. No WiFi is available aboard the ship, and cell coverage should not be relied upon in the remote regions that the Ombak Putih sails.
Cabins & Deck Plan Aboard Ombak Putih
Ombak Putih can accommodate 24 guests in complete comfort and superb style. Her 12 cabins are a study in the efficient use of space aboard a ship—all boasting modern conveniences such as USB charging ports, air conditioning, stylish fixtures and ensuite bathrooms with a hot shower and toiletries. The beach sarongs and towels, reusable water bottles and small day-pack that await guests on the berth make it clear that time won’t be spent inside peering through the brass porthole. Towels and beach towels are regularly changed. There is ample space to store belongings and still move about with ease. Valuables and travel documents can be stored in the ship's safe. Voltage on board is 220 volts. In each stateroom there is a socket suitable for 2-way European plugs as well as USBs.
