The “Sepik Spirit”, constructed in 1989, is built specially to suit the demands of a shallow riverboat for guiding inland waterways. Its shallow draft allows passengers into distant corners of the Sepik Region and areas not otherwise accessible to larger boats. It was refurbished(装修) in early 2006 to ensure that the Sepik Spirit meets the expectations of the modern travellers. The refurbishment includes new interior and improved noise resistance.

The Sepik Spirit holds 18 passengers in 9 twin bedrooms each with private bathroom. Onboard facilities include a dining room, living room, bar, video and covered upper observatory deck(甲板). The entire boat is air-conditioned. Because the Sepik Spirit is designed to operate in this unique environment, she is the ideal size for exploration. This, combined with small passenger numbers, allows the travellers an excellent experience to little visited areas.

Day trips from the Sepik Spirit are done in an 18-seater riverboat, also designed for the operation. Their open-air design gives the travellers a sense of place, a feeling for the river and its people.

Areas that the Sepik Spirit and her guests may visit are the Karawari River, Blackwater Lakes, Chambri Lakes, the Middle Sepik and the Upper Sepik. The river banks where the boat operates are dotted with many large traditional villages each with its own unique “Haus Tambaran” or spirit house decorated with ancestral figures. Mix with the friendly people and experience a culture that meets very few outsiders.
