A Seakeeper is a computer-controlled gyroscope that eliminates up to 95% of boat roll. Its proprietary design, inspired by aerospace technology, centers on a powerful steel flywheel that spins at high speeds in a near vacuum, eliminating air friction and allowing weight, heat generation and power consumption to be minimized. The technology works in all sea conditions, both at rest and underway. Completely self-contained, the Seakeeper produces no drag and, unlike a fin stabilizer, has no risk of damage from impact or snag. A Seakeeper can be installed as a new build feature or can be retrofitted to virtually anywhere on the boat.
