The Coast Guard has implemented a temporary safety zone in Duluth-Superior Harbor, set from February 24 to March 5, 2021. This zone is designed to ensure safety during an extreme sports event and spans from Connor's Point Marina in Superior, WI, to Rice's Point in Duluth, MN, extending 100 yards from barges placed in the waterway. The rule prohibits entry or anchoring within this zone without permission from the Captain of the Port Duluth. It was enacted without a prior notice due to urgent safety concerns, especially as the harbor is not expected to have vessel traffic due to ice and the closure of the Sault Saint Marie Locks.
Simple Explanation
The Coast Guard is making a special area in the harbor between Duluth and Superior where people and boats can't go because a fun sports event is happening, and they want to make sure everyone is safe. They decided this quickly because the water is icy and boats weren't expected to be there anyway.
