Reporting Boating Incidents

A "reportable" boat incident is any incident (regardless of the number of boats involved) that results in loss of life, personal injuries that require medical treatment beyond first aid by a medical professional, boat or property damage in excess of $2,000, or complete loss of a boat.

Wisconsin law requires every boat operator involved in a reportable boat incident to report the incident without delay to law enforcement officials. In addition, within 10 days of the incident, the operator must submit a written report:

Boat Operator Incident Report:  Form 4100-020 [PDF]

Boat Operator Incident Report, Spanish Version:  Spanish Version USCG Operator Report Form [PDF]

For Law Enforcement Use:  Officer Boat Incident Investigation Report: Form 4100-142 [PDF]
