Invader was the first in a series of 25 high-horsepower tugs built for Crowley Maritime during the 1970s, and these boats are still the mainstay of the Crowley sea-going fleet today. Powered by the largest GM diesels ever built for ocean service, these 9,000 horsepower brutes are famous for their high towing speeds and bollard pull. The 136-foot Invader class boats are, pound for pound, some of the most awesome boats working and are used for everything from ultra-large ocean tows, to tanker escorts, to harbor ship assists.
