What is the indicated speed limit in a "slow-no-wake" zone?

In a "slow-no-wake" zone, the speed limit is defined as the speed at which a vessel does not produce a wake. This means that when operating a boat in such a zone, the operator must go slowly enough so that the water's surface remains calm and undisturbed, which helps prevent damage to the shoreline, underwater habitats, and other boats in the area.

This concept is particularly important in areas where boats are navigating close to docks, marinas, or residential waterfronts, as excessive wake can lead to erosion and negatively impact the environment. Going at a speed that avoids producing a wake ensures that the safety and integrity of the waterway and its surroundings are maintained.

While other options mention maximum speeds, minimum speeds, or cruising speeds, they do not accurately reflect the primary intent of a "slow-no-wake" zone which specifically focuses on eliminating wake generation rather than merely regulating speed.
