In a cylinder milled from stainless steel and filled with biodegradable hydraulic oil, there is a spring element next to the internal piston, which is responsible for mechanical damping. In addition, the hydrodynamic resistance of the oil reduces the ship's movements. The Italians currently offer the Seadamp system in four sizes (weight 5.0 to 5.8 kilograms) with damping capacities from 3100 to 17,000 newtons. This spring will see the launch of iRecovery, an additional module equipped with generators that converts yacht movement into electrical energy.
