The purpose-built 60 ft/18.3m MV Chertan operates out of Milne Bay, Papua New Guinea and offers great value.

The boat, and the diving, is the passion of Captain and divemaster Rob Van Der Loos. His experience and sound knowledge of the area is second to none. The MV Chertan accommodates 10 passengers in 5 twin share, airconditioned cabins with sink. There are 2 shared bathrooms on the top deck.

The itineraries, ranging in length from 4 to 10 nights, are all about adventure, challenge and discovery in conditions that few have experienced. From dugouts to dugongs, from plunging coral drop-offs to towering volcanic mountains, skull caves and thermal springs, from hammerhead sharks to manta rays, the region is truly unique. This is an underwater photographer's paradise - and with two large camera tables (one is two tiered), the Chertan is well equipped. A cruise on Chertan offers unlimited diving for the enthusiast as well as an introduction to the local culture.

Equally special is the ambiance on board Chertan where the crew's priority is your comfort and enjoyment. Onboard the Chertan the living is easy. In addition to diving, fresh food from the region is a key focus.

Water temperatures in the Milne Bay area in the summer months may be as high as 84 degrees F and in winter as low as 77 degrees F. Chertan dives all year round with the exception of February when dive sites may be jeopardized by strong westerlies. During he wet season visibility increases substantially due to the prevailing currents. Even though the wet season only lasts for two to three months, the visibility generally remains high for the months of June, July, August, September and into October. The months November, December, January, March, April and May, though the visibility drops slowly seems to offer a different variety of macro subjects. On both sides there's a trade off.
