Two U.S. Coast Guard ice-breakers are sidelined by mechanical issues, disrupting Great Lakes shipping and ferry service.

Two U.S. Coast Guard ice-breakers, Biscayne Bay and Katmai Bay, are facing mechanical issues that limit their ability to clear ice on the St. Mary’s River, disrupting Great Lakes shipping and local ferry service. Biscayne Bay is restricted to maintenance tasks due to an engineering casualty affecting tight turns, while Katmai Bay is in port for repairs with no return date. The Coast Guard is monitoring ice conditions and reallocating assets, with an additional cutter expected to become operational by Monday to help reduce disruptions.
