BOTH INTERNATIONAL & INLAND Which statement is TRUE concerning a 75- meter power-driven vessel underway at night?

Correct Answer: Option D — She must exhibit forward and after masthead lights.

COLREGS Rule 23(a)(i) and (ii) mandates that power-driven vessels of 50 meters or more in length must exhibit two masthead lights: a forward masthead light and an after masthead light placed abaft of and higher than the forward one. A 75-meter vessel clearly falls under this operational requirement.
