2006 Mariner Orient

This 2006 Mariner Orient is a 40-foot fiberglass sedan trawler powered by a single Cummins QSL9 diesel engine rated at 405 horsepower. The engine has 1,732 hours and is equipped with bow and stern thrusters, an aftercooler, gear cooler, and heat exchanger—all serviced within the past year. A Westerbeke 7.6 generator with 885 hours provides onboard power.

The boat's single-engine configuration keeps systems straightforward and reduces ongoing maintenance demands. One head simplifies plumbing and storage concerns. A Magna Sine Wave inverter draws from a substantial AGM battery bank, and the boat includes a water maker, oil change system, and fuel polisher. A covered walk-around deck aids in docking and securing the boat.

Recent service work includes bottom paint completed at the beginning of 2026. The engine room is uncrowded, allowing good access for maintenance and repairs. This layout and equipment package reflects practical thinking for extended cruising, whether coastal running or extended time at anchor.
