Assembly Bill 249 aims to prohibit the abandonment of boats on state waters or adjacent riparian land in Wisconsin. The bill defines "abandon" as leaving a boat unattended for more than seven consecutive days without intent to return, or leaving a boat in a state of disrepair that poses a hazard to navigation, public safety, or environmental health. If a law enforcement officer identifies an abandoned boat, they must notify the owner, who then has 30 days to remove the boat. Failure to do so can result in penalties, including imprisonment for up to nine months and fines up to $10,000.

The bill also establishes new legal provisions under sections 30.542 and 30.80 (7) of the statutes. Section 30.542 outlines the definitions and responsibilities regarding abandoned boats, while section 30.80 (7) specifies the penalties for violations, including fines and imprisonment. Additionally, violators may be required to complete a safety course before operating a boat, and if they already possess a valid certificate, it will be revoked upon sentencing. The bill emphasizes the importance of maintaining safe and navigable waters in Wisconsin.
