A day to day guide
D A Y 1
Arrive into Ambon where you will be taken straight to Katharina at Harbour.
Ready to start our adventure, depart for the island of Saparua, and visit the Dutch built VOC-Fort Duurstede (1691) stormed in 1817 in a revolt led by Ambonese Kapitan Pattimura, a national hero and martyr. Later, we can enjoy our first snorkelling near the small uninhabited island.
In the evening, we will begin our voyage to the Banda Islands, the original source of nutmeg; in the 15th and 16th centuries, this aromatic spice spurred exploration and shaped colonial empires.
D A Y 2
Explore the coastline of the Island of Suanggi, a small rocky island populated by an enormous, noisy colony of seabirds. We will then continue our journey to the Banda Archipelago, arriving first at the tiny outlying island of Run, where the English and Dutch vied bitterly for control of the nutmeg trade. In 1667, under the Treaty of Breda, Run was the subject of an unbelievable real estate deal when it was ceded by the English to the Dutch in exchange for Manhattan.
After visiting the village and the remains of the British-built Fort Swan, we can snorkel offshore. After lunch, wander the pretty island of Pulau Ai, where we will wander through the village and visit the remains of the Dutch-built Fort Revenge, followed by some more beautiful snorkelling. In the evening we will head to Banda Neira, the main island in the Banda chain, where we will anchor in a small, protected bay in the lee of Gunung Api volcano.
D A Y 3 – 4
The Banda archipelago is made up of many islands and guests have the choice to explore the outer islands of Lonthoir, Ai, Run and Hatta. Each island has its own history from old plantation ruins, Dutch cemeteries and European fortifications. The tiny island of Run was the subject of an unbelievable real estate deal in 1667, when under the Treaty of Breda, it was surrendered by the English to the Dutch in exchange for Manhattan.
Visit Fort Revenge on the island of Ai or enjoy the tranquil beauty on Lonthoir as you wander the nutmeg groves where shapely fruit bearing trees grow in the shelter of the native almond trees. With a bit of luck and guidance from the locals, we should be able to spot the elegant Imperial Pigeon – a species that Wallace himself discovered and named. These funny creatures feast on whole nutmegs which the local still harvest by hand using age-old techniques. Guests can buy the baked goods, condiments and jams flavoured with fresh mace and nutmeg – a delicacy rarely obtainable outside of the Banda Islands.
Climb the fortress of Hollandia as we meet the local “perkeniers” – a small holder farmer managing plantations. Learn about the war and conflict that shook these lovely islands which is hard to believe given their current peace and tranquillity.
Leaving the Banda Islands, the boat will navigate through the Sonnegat between Neira and Gunung Api, possibly escorted by kora-kora – giant Moluccan galley ships traditionally used for ceremony and warfare, propelled by warrior-oarsmen
Since conditions of wind and tide will determine the order in which we visit various islands, we cannot guarantee any particular order. On the biggest island of Neira, guests can stroll through the quaint colonial outposts characterful streets, inspecting notable residences, a museum, churches and a waterfront market.
Across the harbour is the jungle-clad volcanic island cone of Gunung Api (fire mountain) and for the more ambitious guests, an early morning ascent up a challenging track provides stunning views across the islands.
The islands are also home to excellent coral reefs nearby where we can watch some amazing marine life and if we are out at dusk, we will have a good chance of seeing arguably the world’s most stunning fish – the jewel-like Mandarin Fish.
D A Y 5
We will wake up off the coast of Pulau Igar, an island in the north of the Watubela Archipelago, where we can enjoy some morning snorkelling and beach activities. At midday, we will continue north to Pulau Manawoka.
In the afternoon we can visit the friendly villagers of Amar Sekaru, who will happily guide us through their beautiful plantations. Near the village, we will find the two little lakes of Sole, connected to the sea by a small tunnel. Swimming in these lakes and tunnel evokes the feeling of discovering an unknown planet. Overnight we will continue our journey to Pulau Daram in Raja Ampat.
D A Y 6
We should arrive at the island of Daram by mid-morning, allowing us the opportunity for some trekking, snorkelling, kayaking, stand-up-paddle-boarding and beach activities.
At lunchtime we will continue to Pulau Farondi, northwest of Daram, where we can snorkel in the late afternoon.
In the evening we will cruise to the village, where the Katharina will spend a quiet night at anchor in anticipation of our morning quest to see the lesser bird of paradise in the wildlife.
D A Y 7
Today We will rise around 4 am and have a quick breakfast and go ashore, where local guides will be waiting for us to take us through the forest to hopefully see the Lesser bird of paradise as they dance around in their ‘lekking’ trees.
We will have time for a look around the village and possibly a visit to the school and to learn about the way Nature Conservancy is working with the village to empower with local women with a fishing practice called sasi. Mid-afternoon we will set off to the eastern side of Misool to Tomolol Bay.
D A Y 8
This morning we will wake to see the sunrise over the picturesque chain of islands that makes up the eastern part of the Misool archipelago. The topography is typical of ‘karst dissolution,’ featuring a great number of tiny islets whose bases have been eroded over time by the relentless motion of the tides.
After an early breakfast, our tenders will take us into the heart of the bay to see this partially submerged cave where it is possible to swim and snorkel while gazing up at the cavernous grotto adorned with astonishing stalactites.
We will then move on to the mysterious jellyfish lake and swim amongst the many thousands of stingless animals.In the afternoon, we will use our tenders to explore more of this impressive maze of karst islands, both above and below the surface, complete with mysterious skull cairns in sea-cave cemeteries, and prehistoric cave paintings, estimated to be anything between 3,000 to 5,000 years old and depicting various human figures and huge human palms, fish, flowers and plants, tools and vessels.
D A Y 9
We will emerge from our cabins in the southwest corner of Kabui Bay next to ‘Wallace’s Channel’ where Wallace emerged after his very challenging sail from Seram.
After breakfast, we will take dinghies through the narrow channel, examine the vegetation clinging to the limestone cliffs, and snorkel at a few contrasting sites. We will then return to the ship and head out of the bay.
We will spend the afternoon in a local village where Wallace spent some months and (if the tides are right) we’ll visit a faithful replica of Wallace’s small hut, which was built with a grant from SeaTrek. Followed by a visit to a nearby small island where a local man has set up a coconut crab ‘sanctuary’. The island is home to a small number of the animals (Birgus latro, the world’s largest terrestrial arthropod.
Another late afternoon snorkel along a reef with some spectacular giant clams will lead us into dinner at anchor on board, ready for an early morning venture for the Red Bird of Paradise.
D A Y 1 0
After our encounter with the red bird of paradise, we will make our way through the Dampier strait, home of some of Raja Ampat’s premier reefs. With a bit of luck, we hope to snorkel with some of the larger marine life attracted to the strait’s nutrient-rich currents.
We will end our day in front of small Village, where we can easily circumnavigate the tiny island by foot and get a sense of the Asai culture, which is still kept alive by the villagers living on this tiny isolated island. This village is also home to a local manta conservation project where volunteers will happily show us around and explain their efforts and programs in more detail.
D A Y 1 1
It will be an early morning start as the dinghy takes us in the dark over to the village and a local guide will take us on a 20-minute walk into the forest. As dawn breaks in the forest canopy, we should get good views of the bright Red Bird of Paradise. Back in the village, there will be time to meet with the community and perhaps visit the school.
We will be back on the boat by mid-morning and if time permits we’ll travel over to Pef Island to snorkel and motor around the convoluted coast while learning the myth about the prehistoric handprint still visible high on a limestone cliff.
In the afternoon we’ll head towards Sorong and should have time for a snorkel before dinner.
D A Y 1 2
After breakfast, we will stroll around the island near Sorong with traditional transportation called Becak. During the First World War, Doom island served as an administrative centre of Dutch Empire administration in West Papua and continued to become the core of Sorong for some time before the city grew in mainland Papua. During the Second World War, Japanese forces occupied and fortified the island, building a network of tunnels and bunkers.
The island was attacked by American and Australian aircraft throughout the war. Following the war, a fishing station was briefly established on the island before it was moved to Manokwari. When we back on the boat, we will say goodbye to our tour leaders, crew and captain and transfer you to the airport or hotel for your onward travel.

Jeffrey has shared his knowledge and enthusiasm for this oceanic world by leading tour groups exploring maritime themes in Indonesia, Malaysia, Cambodia and India.
Please note that this is a guide as to what to expect from your sailing holiday in Indonesia. With the ever changing wind and tides, flexibility is key. Our mission is to provide the best experience possible for our guests given the current conditions and when unexpected opportunities for adventure may present themselves along our cruise routes.
Sometimes weather conditions, tides or other local factors dictate that we need to vary from the published route, and at times there are special opportunities to explore and discover new locations, events and activities. These explorations will always be a definite enhancement to the published itinerary and will be undertaken after discussion and agreement among guests. Ultimately, the boat captains and your tour leader will make decisions to maximise trip safety and your overall enjoyment, so please come prepared to be flexible!
All voyages for Katharina
Katharina
Guest berths: 14 Rig: Gaff Ketch
Built in 1995 on the Indonesian portion on the island of Borneo, Katharina was originally planned for use a commercial freighter but caught the eye of her current owner with her elegant sailing lines and sleek hull shape.
They saw her transformation into a charter vessel as an exercise to conserve her Indonesian authenticity and in 2014, employed local craftsmen to complete a beautiful interior refit. Working alongside her sister ship Ombak Putih, (larger but equally as beautiful!), they are both fine examples of some of the few original boats that still sail these waters.
Now led by Captain Ferdi, Katharina takes guests on skippered sailing holidays to explore the cultural heritage, natural wonders and wildlife of the Indonesian islands.
