What must you do when operating a boat within 50 feet of a dock?

When operating a boat within 50 feet of a dock, you must reduce your speed to a no-wake level to prevent creating large waves that could damage the dock or nearby vessels. Additionally, maintain a safe distance from other boats and be vigilant for pedestrians or objects in the water. Ensure you are prepared to maneuver your vessel safely and follow any local regulations regarding docking areas.
