Master Boat Builders Starts Construction of Crowley’s Zero-Emission Tug
Master Boat Builders has begun construction of Crowley’s eWolf, the first all-electric ship assist tug in the U.S., at its shipyard in Coden, Ala.

“Initiating construction of the first-ever fully electric U.S. tugboat, the eWolf marks a historic moment for Crowley and Master Boat Builders,” said Garrett Rice, president of Master Boat Builders. “Today is also a remarkable milestone for the entire U.S. maritime industry, as we work toward providing groundbreaking net zero-emission maritime capabilities”.
The 82-foot harbor tug is expected to be completed and ready for service in mid-2023 at the Port of San Diego, in a partnership with federal and California agencies. The eWolf features a design that allows the vessel to operate fully electric while maintaining full performance capabilities – and zero carbon emissions. The eTug will feature an integrated electrical package provided by ABB.
The eTug will be constructed under the design and on-site construction management of Crowley Engineering Services, the company’s naval architecture and marine engineering group.
“We are excited to begin construction of eWolf at Master Boat Builders on a vessel that will open a new chapter in sustainable maritime services in America’s harbors,” said Ray Martus, vice president, Crowley Engineering Services. “We look forward to working with the men and women of MBB to deliver a high-performance vessel that offers increased efficiency and safety for our mariners.
The eWolf embodies Crowley’s dedication to sustainability. Crowley recently announced its commitment to reach net-zero emissions across all scopes by 2050. Click here for more on its sustainability commitment and partnerships.
