Built in 1975, the Lassen is a 66-foot tugboat made for tough jobs. Its MTU main engines and ZFW reduction gears push out 2,300 horsepower, delivering the strength needed for demanding operations. The reinforced ABS-grade steel hull stands up to harsh conditions, while a three-coat paint system adds extra protection. Stainless steel propeller shafts and bronze propellers ensure smooth, reliable performance.
