Does Michigan Law or Federal Maritime Law Apply to a Boating Accident?

It depends on the facts. Michigan boating rules apply to many incidents on state waters, and federal law can become relevant in other circumstances. Michigan's Department of Natural Resources enforces boating laws on state waters, while the U.S. Coast Guard has federal responsibilities on the Great Lakes.

An accident happening on water does not automatically make it a federal maritime case. Where the accident happened, what vessel and activity were involved, whether the waterway was navigable, and whether the injured person was a passenger, recreational boater, or worker can all matter.
