Vessel oscillation damper system

A vessel oscillation damper system, comprising one or more pairs of fin assemblies (20), mounted in the transom of the vessel (60) and symmetrically with respect to the vertical axis (x) passing through the center of the transom of the vessel, consisting of a number of individual fins (21) connected to each other, a drive system of the fin assemblies (25), a fin assembly position sensor system (30), an electronic controller (35), consisting of a gyroscope (36), an accelerometer (37), gps (38) and a fin assembly position sensor (39), one or more control screens (45), a fin assembly retract button (55) and an information transmission system between these, with manual and automatic operation, characterized in that, the fin assembly (20) consists of multiple successive individual fins (21) arranged in the vertical direction, each of which has a P-type cross-section, consisting of a base and two intersecting sides, where the sides of the upper fin are tangential to the sides of the immediately lower fin, forming successive closed ducts through which water passes,

• the fin assemblies (20) rotate clockwise above the water level and counterclockwise, by their articulated connection (22) with the vessel, parallel or independent of each other and simultaneously opposite and parallel,
• it includes an impact sensor (40), installed on the electronic controller (35) that receives a load and consumption data feed from the vessel's engine, monitoring if there is increased fuel consumption and from the gps (38), receives a speed and direction of movement of the vessel data feed, for reduced speed and constant changes in the direction of movement, which in turn signals to the electronic controller (35), to rotate the fin assemblies (20) in such a way as to adjust the inclination of the boat in terms of pitching,
• includes an emergency stop safety device, through which, when activated via the emergency stop button (50), all the flap assemblies (20) are instantly rotated counterclockwise, lowering the bow, halting the speed of the boat forcibly.
