BOTH INTERNATIONAL & INLAND Except where specifically required by the rules, a sailing vessel is NOT required to keep out of the way of which vessel?

Correct Answer: Option A — power-driven pilot vessel on station

Rule 18(d) states that a sailing vessel shall avoid impeding the passage of a vessel restricted in her ability to maneuver or a vessel engaged in fishing. A power-driven pilot vessel on station is not included in the list of vessels that a sailing vessel must keep clear of.
