Its work typically takes it from Hawaii to the Pacific Northwest to Alaska.The Redlinger is based in Portland, Ore., and provides hydrosurvey data for areas along the Columbia and lower Willamette rivers. She is part of a new generation of survey boats, with a hydrofoil-assisted catamaran design that provides a stable platform to monitor channel and harbor conditions and provide high quality, precise surveys of areas in need of dredging. The vessel is designed for exceptional maneuverability. Her hulls are coated with a paint that makes it impossible for sea-life to adhere. The Redlinger’s diesel engines fewer harmful emissions, and her fuel tanks stand alone inside the hulls, providing an additional layer of protection in the event of a fuel spill.A legacy of excellence
