How many masthead lights must a 50-meter vessel display?

• A. One masthead light only
• B. Two masthead lights
• C. Three masthead lights
• D. No masthead lights

Answer: (B)

A 50-meter vessel is classified as a vessel of a certain size that requires specific navigation lights according to the International Regulations for Preventing Collisions at Sea (COLREGs). For vessels 50 meters in length or more, the regulations state that they must display two masthead lights. The purpose of having two masthead lights is to enhance visibility and to signify the size and operational status of the vessel to others on the water, especially at night or in poor visibility conditions. The presence of two masthead lights indicates that the vessel is longer and larger, which is crucial information for other mariners to avoid potential collisions. In smaller vessels under 50 meters, only one masthead light is required, while larger vessels above 50 meters must display this additional light to comply with maritime safety regulations. Thus, the requirement of two masthead lights for a vessel of this size is an important aspect of the COLREGs designed to promote safe navigation.
