BOTH INTERNATIONAL & INLAND Which statement is TRUE of a 30-meter sailing vessel underway?

A She need not show a stern light if she is showing all-round lights on the mast.

B If she is using propelling machinery, she shall show forward a shape consisting of two cones, apexes together.

C She may show an all-round white light at the top of the mast.

D She must show sidelights and a stern light in restricted visibility.

AI Explanation

The correct answer is D) She must show sidelights and a stern light in restricted visibility. This is correct because the International Regulations for Preventing Collisions at Sea (COLREGS) require a sailing vessel underway, regardless of size, to exhibit sidelights and a stern light in restricted visibility. This is true both for international and inland waters. The other answer choices do not accurately reflect the COLREGS requirements for a 30-meter sailing vessel underway.
