INTERNATIONAL ONLY Which is the minimal lighting requirement for a power-driven vessel less than 7 meters in length, with a maximum speed which does not exceed 7 knots?

Correct Answer: Option B — One white 360° light

COLREGS Rule 23(c)(i) explicitly permits a power-driven vessel under 7 meters with a maximum speed not exceeding 7 knots to carry one all-round white light as its sole navigation light. This is a specific exemption for small, slow-moving craft to ensure they remain visible to other traffic.
