When can a boat operate in a NO WAKE zone?

Operating a boat in a NO WAKE zone requires that the vessel moves at idle speed to maintain minimum wake. This regulation is designed to protect the shoreline and other vessels from damage caused by large waves or wakes created by faster-moving boats. Idle speed minimizes the water disturbance and is essential in areas where vessels are in close proximity to each other or to areas with swimmers, docks, or sensitive environmental locations.

The other options don't align with safe boating practices in a NO WAKE zone. Operating at full speed would create significant wakes, contrary to the purpose of the zone, while considerations like sunset or busy hours are irrelevant to the requirement of maintaining an idle speed. Thus, the focus remains on preventing wake-related damage and ensuring safety in controlled areas.
