Assembly Bill 1045 introduces new regulations concerning wake-enhanced boating in Wisconsin. The bill defines "wake-enhanced boating" as the operation of a motorboat that intentionally creates or enhances a wake for activities such as wakesurfing or wakeboarding, utilizing various devices to increase wake size. It establishes specific conditions under which wake-enhanced boating can occur, including a requirement that it must take place at least 500 feet from the shoreline and in water that is at least 20 feet deep. The bill clarifies that local governments retain the authority to impose more stringent regulations on wake-enhanced boating, including restrictions on specific areas, distances from shore, and time-of-day limitations.

Additionally, the bill provides civil immunity to state entities and their officials for enacting or enforcing local ordinances that impose stricter regulations on wake-enhanced boating than those outlined in state law. This immunity is intended to protect local governments and their employees from legal liability when they act in good faith to regulate wake-enhanced boating. The bill aims to enhance safety and environmental protection on Wisconsin's waters while allowing local jurisdictions to tailor regulations to their specific needs.
