A new SeaKeeper was recently installed aboard a Viking 38. The unit is designed to provide total motion control, whether underway or “adrift” trolling for the next big tuna! How does it work? When the boat rocks, the SeaKeeper performs. As if by magic, a gyro tilts fore and aft, producing a powerful gyroscopic torque that counters the boat’s motion and stabilizes the vessel. A SeaKeeper is capable of eliminating up to 95% of a boat’s roll.
