In addition to the sidelights and stern light, what light must a sailboat 23 feet or longer display at night when engines are in gear?

• A. Red light
• B. Flashing light
• C. Steaming light
• D. Green light

Answer: (C)

A sailboat that is 23 feet or longer must display a steaming light at night when the engines are in gear to indicate that it is under power. The steaming light is a white light positioned on the centerline of the vessel, usually at the top of the cabin or mast, and it helps other vessels understand that the sailboat is not only under sail but also using its engine. This lighting requirement is crucial for safe navigation in the dark, as it clarifies the boat’s operational status to other mariners, reducing the risk of collisions. The sidelights (red for port and green for starboard) and stern light provide additional information about the sailboat's orientation and direction. The other options, such as a red light, flashing light, or green light, do not fulfill the regulatory requirement for vessels under power. The red and green sidelights serve different purposes, while a flashing light does not apply to standard navigation lighting for sailboats in motion. Thus, the steaming light is the correct answer as it specifically addresses the situation described in the question.
