What action must a boat operator take when approaching a "slow no-wake" zone?

When approaching a "slow no-wake" zone, the appropriate action for a boat operator is to reduce speed and maintain control. This zone is specifically designated to minimize the wake produced by boats, which can cause erosion, disturb wildlife, and create safety hazards for other boaters or swimmers in the vicinity. By reducing speed, the boat operator ensures that the wake generated is minimal and adheres to the regulations of that area.

Maintaining control is equally important as it allows the operator to navigate safely, especially in potentially congested areas where other boats or obstructions might be present. This cautious approach helps to promote safe boating practices and respects the environment and community. Other options, such as accelerating to cross quickly or stopping immediately, do not align with the purpose of the "slow no-wake" zone and could lead to dangerous situations on the water. Turning around unnecessarily would also be impractical, as it does not address the requirement to operate safely in that designated zone.
