Description

J.M. Martinac Shipbuilding in Tacoma, WA, United States, has been building ships since 1924. The company started with fishing vessels, and over the years has built more than 300 vessels of various types. Martinac’s latest project, the Northern Leader, is the largest longliner ever built in the US and one of the largest in the world. It is also eco-friendly.

The propulsion is powered by propellers supplied by Schottel, a long-term customer of Vacon. This is the first time Z-Drives have been installed on a longliner. The two Schottel Z-Drive rudder propellers are each controlled by a 1,000 kW VACON® NXP Liquid Cooled drive, and one Schottel tunnel thruster is controlled by a 300 kW VACON NXP Air Cooled drive.
