    • A light-weight, strong, low cost fin for ship stabilization. The fin is composed of plastics materials, such as polystyrene, polyurethane, and the like. The fin is strong and durable in its use as a ship stabilizer. However, the type of materials used in the fin permit the fin to be readily crushed or broken upon impact with other objects, to prevent transmission of forces to the ship which might damage the ship which is stabilized by the fin.
    • 轻型,强劲,低成本的船舶稳定性。 翅片由诸如聚苯乙烯,聚氨酯等的塑料材料组成。 翅片在作为船舶稳定器使用时坚固耐用。 然而,在翅片中使用的材料类型允许翅片在与其它物体撞击时容易被压碎或破碎,以防止能够损坏由鳍稳定的船舶的船舶的力传递。
