History: Custom-built in 1986 for Seventh-Day Adventist Church as a hospital ship, the Oceana Ranger is unique. It was designed to be a workhorse of the oceans: safe, strong, reliable, comfortable and cheap to operate. The Oceana Ranger had travelled through Micronesia on medical and church missions and has crossed the Pacific dozens of times before becoming Oceana's ship.
Safety: The Oceana Ranger was built to American Bureau of Ships (ABS) standards, the most stringent in the world. The vessel has 10 watertight compartments, and even if the two largest are flooded, it can still make way safely under sail or motor. The Oceana Ranger can cruise on one of the two diesels or on one of the two sails.
Resistance: Unlike normal vessels, the Oceana Ranger is made almost entirely of marine alloy 5086 aluminium, a corrosion-resistant material that welds to almost 100 percent strength, instead of the 65 percent strength for the 6061 extrusions sensible to corrosion used in other vessels. The Oceana Ranger can face tough tests on its 5/16-inch bottom sheets and pound for hours in the surf under extreme conditions without affecting its integrity. LeFeill, builder of high-tech tubing for spacecraft, engineered and built the sailing rig to withstand tough conditions at sea.
Reliability: Every system has a backup: there are two fixed GPS systems incorporated to chartplotters, five ways to generate DC current, two ways to generate AC current, three depth sounders, two anchor lines, two HF radios and two fixed VHF radios. There is a Sat-Com system that provides e-mail via satellite allowing email access.
Economy: Drinking water can be made from seawater, caught from rainwater or taken aboard from shore.
The research catamaran Oceana Ranger is crewed by experimented professionals and it has all the equipment and technology to carry out the tasks needed to develop research campaigns. It is equipped on board with OLEX bathimetry systems, navigation computer with MaxSea charting, Oceanography winch with metre-counting snatch and Van Veen dredger.
