Fin Stabilizers

Fin Stabilizer

Our fin stabilizers feature an extremely responsive hydraulic system and have powerful computational ability. They deliver optimal responses to changing wave patterns, and by using “fuzzy control” can handle even the most irregular waves.

Main Features

  • Cutting-edge technology

In 1920, we developed the world's first fin-type stabilizer, which was installed on a passenger ship operating between Hakata and Tsushima in Kyushu, Japan.

In 1983, we established a technical collaboration with Vosper Thornycroft (U.K.) Limited, a British manufacturer of fin stabilizers, and began making fin stabilizers with a non-retractable design for defense ships and patrol boats.

In 1988, we developed a retractable fin stabilizer for merchant vessels such as ferries and cruise ships, heralding a new era in smooth sea travel.
