A sailing vessel underway must keep out of the way of which of the following?

• A. A boat not under command.
• B. A boat restricted in its ability to maneuver.
• C. A boat engaged in fishing.
• D. A sailing vessel underway.

Answer: (C)

The key idea is that certain vessels have limited ability to maneuver, so others must take action to avoid them. A sailing vessel underway must keep out of the way of a vessel that is not under command, a vessel restricted in its ability to maneuver, and a vessel engaged in fishing. Among these options, a boat engaged in fishing stands out because fishing gear (nets, lines, gear) can extend well away from the vessel and constrain its ability to maneuver, making it hard for them to avoid others. To prevent collisions, the sailing vessel should give way to a fishing vessel.
