Final answer:
The maximum vessel speed when passing close to state-owned boating or fishing access areas is typically "idle speed" to ensure safety and prevent wake damage.
Step-by-step explanation:
The maximum vessel speed when passing within 50 yards of a state-owned or state-controlled boating or fishing access area is generally set at the safest and least disruptive speed which, in most cases, is "idle speed". This is the minimum speed that allows for safe navigation and is often used to prevent wake damage and ensure the safety of those in the vicinity, including swimmers and other boaters.
