Crescent Towing and Blakeley BoatWorks, Mobile, Ala., are continuing their partnership with plans to begin construction of hull 115, a new 6,000-hp, Tier 4, Z-drive tugboat, to be added to Crescent Towing’s Mississippi River ship assist operations, based in New Orleans, upon completion.

The 49-foot solar-powered vessel Firefly, now under construction at Lyman-Morse Boatbuilding in Maine, is designed to carry students on STEM-focused educational trips along the Delaware River for the nonprofit Upstream Alliance. Powered by high-efficiency solar panels, electric motors, and lithium-ion batteries, Firefly will promote clean energy, environmental awareness, and hands-on science learning for middle and high school students.
