When operating a boat when should you have your appointed lookouts in place?

When operating a boat, appointed lookouts should be in place at all times, especially in busy or restricted waterways, during low visibility conditions such as fog or nighttime, and when navigating through potentially hazardous areas. Lookouts help monitor for other vessels, obstacles, and changing environmental conditions, enhancing overall safety. Their presence is crucial for effective communication and timely responses to any potential dangers.
