Features

The Mega-Guard Electric Fin Stabilizer (EFS) provides comfort to the ship by active controlling a portside and starboard side mounted fin in order to reduce rolling of the vessel. Mega-Guard EFS is a full electric system and the fins are driven by a permanent magnet motor with integrated gear. The fins are available for ships ranging 18 to 50 meter and vary in size in between 0,6m² to 2.5m². The Electric Fin Stabilizer works at every speed and it includes a zero speed mode and an anchor walk prevention mode. The EFS is operated through a user friendly 5.7” touchscreen for intuitive operation and monitoring. The EFS Operator Panel is available in two versions: with a metal front for commercial ships and with a highly esthetic glass front for mega yachts. Mega-Guard EFS is designed for quiet operation and low power consumption. The Electric Fin Stabilizer is powered from DC bus voltages in between 384VDC and 960VDC.
