Watercraft: other; use of maritime pilot and marking of obstructions; require, and prohibit use of anchors in Straits of Mackinac. Amends 1994 PA 451 (MCL 324.101 - 324.90106) by adding pt. 784.

This bill establishes new regulations for large watercraft, defined as vessels over 700 feet long, navigating the Straits of Mackinac. It mandates that these vessels must be guided by a licensed maritime pilot and strictly prohibits the use of anchors or any equipment that could touch the lake bottom within the designated area. Additionally, the legislation requires the state to install buoys to mark navigation hazards and designates specific emergency anchorage zones. Owners of obstructions in the straits are also required to mark their property with buoys within 90 days to ensure safe passage. Violations of these rules are classified as felonies, carrying potential prison sentences, fines, and mandatory reimbursement for environmental cleanup costs.
