Final answer:
The true statement according to the 'Rules of the Road' is that a vessel engaged in fishing while underway must keep out of the way of a vessel restricted in her ability to maneuver.
Step-by-step explanation:
The statement that is TRUE, according to the international maritime 'Rules of the Road' (part of the International Regulations for Preventing Collisions at Sea - COLREGs), is: A. A vessel engaged in fishing while underway shall, so far as possible, keep out of the way of a vessel restricted in her ability to maneuver. This rule is derived from the COLREGs, which is a set of international rules followed by ships and other vessels at sea to prevent collisions and ensure maritime safety. Vessels that are restricted in their ability to maneuver, due to the nature of their work, have the right-of-way over vessels engaged in fishing. The other options provided present situations where those rules are not applied correctly according to the international maritime conventions.
