Question

The responsibility for maintaining a proper lookout using human sight and sound on a boat underway applies to boats during what times

Answer 1

The responsibility for maintaining a proper lookout using human sight and sound on a boat underway applies to boats all the times. Because a boating failure to maintain a proper lookout by all useful means available, is a major cause of collision of boats underway which directly violates the rules and reduces safety of all boats in the area.
