BOTH INTERNATIONAL & INLAND The lights displayed in illustration D044RR below would be shown by a vessel described by which of the following?

Correct Answer: Option A — aground

Rule 30(d)(i) requires a vessel aground to exhibit the anchor lights prescribed for her length, along with two all-round red lights in a vertical line. Illustration D044RR depicts this specific configuration, distinguishing an aground vessel from one that is merely anchored or not under command.
