BOTH INTERNATIONAL & INLAND Which craft is a "power-driven vessel" under the Rules of the Road?

Correct Answer: Option D — All of the above

Rule 3(b) defines a power-driven vessel as any vessel propelled by machinery. A canoe with an outboard, an auxiliary sailing vessel using its engine (even with sails up), and a trawler transiting to fishing grounds under engine power all meet this definition, making all options correct.
