Introducing the eWolf 2024 Tugboat of the Year Powered by Markey’s Hawser Winch

The maritime industry is witnessing a groundbreaking advancement with the introduction of the Crowley eWolf, recently named the 2024 Tugboat of the Year by Professional Mariner. This pioneering electric tugboat heralds a cleaner and more efficient future for the U.S. towing fleet. At the core of its operational success lies Markey Machine‘s cutting-edge Hawser Winch, a testament to our commitment to innovation, quality, and reliability.

Pioneering Innovation in Marine Technology

The Crowley eWolf stands out as the first fully electric tugboat in the United States, marking a significant shift towards zero-emission operations. Designed from the keel up by Crowley’s engineering services group, this vessel reflects a significant shift towards zero-emission operations. With a powerful 4,200-kW (5,632-hp) propulsion system generating 73 tons of bollard pull ahead and 70 tons astern, eWolf showcases remarkable performance without the noise, vibration, or emissions of traditional diesel-powered tugs.
