The University of Wisconsin-Superior’s new education and research vessel, Sadie Ann, will spend the winter in Beaufort, North Carolina, as the university continues commissioning and testing the vessel and its advanced propulsion system.
The decision follows an unexpected stop during the vessel’s voyage from Louisiana to Superior, Wisconsin, after a mechanical issue required a replacement engine component. While the delay means Sadie Ann will not arrive in Superior this fall as originally planned, university officials say taking additional time to thoroughly evaluate and refine the vessel’s systems is the most responsible path forward.
Like any newly constructed vessel, Sadie Ann is undergoing a period of testing and adjustment as it transitions into service. The process is especially important because the vessel features a diesel-electric parallel hybrid propulsion system, an emerging technology that combines components from multiple manufacturers in a first-of-its-kind configuration.
“This is exactly the type of real-world learning and problem-solving that comes with introducing innovative technology,” said Matthew TenEyck, director of UW-Superior’s Lake Superior Research Institute (LSRI). “Our priority is ensuring the vessel is fully tested, understood and ready to serve students, researchers and partners for years to come.”
The vessel is expected to arrive in Beaufort by mid-October, where it will be hauled out and stored at Safe Harbor Jarrett Bay. The secure facility will allow LSRI staff and industry partners to continue evaluating systems, completing improvements and installing educational equipment while taking advantage of North Carolina’s mild winter climate.
Designed to support environmental research, education and outreach across the Great Lakes, Sadie Ann will provide students, researchers and community partners with hands-on access to a modern research vessel and emerging maritime technologies.
The extended commissioning period also provides valuable opportunities for mechanical troubleshooting, systems evaluation, operator training and performance refinement. Lessons learned during the vessel’s first year will help ensure reliable operations and contribute to broader knowledge about hybrid propulsion systems and their application in the maritime industry.
“Our goal is to work through these challenges carefully and methodically,” TenEyck said. “When Sadie Ann arrives on Lake Superior, it will be better tested, better understood and fully prepared to fulfill its educational and research mission.”
UW-Superior and UW-Superior Alumni & Friends Foundation leaders are planning a celebration event with tours of the vessel when Sadie Ann arrives in Superior in the spring.
National Recognition for Innovation
Even as commissioning continues, Sadie Ann is already receiving national recognition for its innovative design.
WorkBoat magazine recently selected the vessel for its annual Significant Boats program, which recognizes 10 vessels that stand out for innovation, design, construction or impact on the maritime industry.
The recognition highlights the collaborative effort behind the project. UW-Superior partnered with Midship Marine and Incat Crowther to design and construct a vessel that brings cutting-edge maritime technology into an educational setting, creating opportunities for students and researchers to help shape the future of Great Lakes maritime operations.
