(JACKSONVILLE, Fla.) ­— Master Boat Builders has begun construction of Crowley’s eWolf, the first all-electric ship-assist tug in the United States, 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 (Dec. 6) 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 tug features a design that allows the vessel to operate fully electric while maintaining full performance capabilities – and zero carbon emissions. The vessel will feature an integrated electrical package provided by ABB.

The tug 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.”
