Shipping industry leaders in the Great Lakes say vessels lost a combined 82 days' worth of delays.

They're attributing this to, quote, inadequate icebreaking operations by the U.S.

Eric Peace is with the Lake Carriers Association.

The Coast Guard says their operations were efficient when assisting hundreds of vessels to safety.
