358. BOTH INTERNATIONAL & INLAND At night, you see a vessel displaying the light shown in illustration D046RR below. Which vessel would exhibit this light?

The illustration depicts a single all-round white light, which is permitted for small sailing vessels under Rule 25(d). Pilot boats display white over red lights, fishing vessels show red or green over white lights, and fishing vessels at anchor must continue to display fishing lights. Therefore, the correct answer is a sailing vessel.
