The automatic trim tab systems are equipped with nitrogen cylinders, suitable for any length and type of boat. Their operation is simple, as is their installation, since no cables or other electromechanical installations are required.

During low speeds, the nitrogen cylinders keep the fins lowered, while at higher speeds they allow the water pressure to move the fins vertically according to the required force (engine/boat ratio). This results in additional stern lift at lower speeds, creating better sailing conditions, as well as faster planning for reduced fuel consumption.
