BOTH INTERNATIONAL & INLAND When is a fishing vessel required to show sidelights and a stern light?

Correct Answer: Option D — underway and making way

Rule 26(b)(i) mandates that a vessel engaged in fishing, when underway, shall exhibit sidelights and a stern light. Under Rule 3(i), a vessel is 'underway' when not at anchor, made fast to the shore, or aground. 'Making way' implies the vessel is moving through the water.
