BOTH INTERNATIONAL & INLAND Which vessel may use a lantern combining the sidelights and stern light?

A sailing vessel of 25 meters in length
B 6-meter vessel under oars
C 25-meter power-driven vessel engaged in trolling
D 20-meter vessel engaged in fishing and making way
AI Explanation

The correct answer is B) 6-meter vessel under oars. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel under oars, regardless of length, may use a lantern combining the sidelights and stern light. This is specified in Rule 25(d) of the COLREGS. The other options, such as a sailing vessel of 25 meters or a power-driven vessel engaged in trolling or fishing, are required to display separate sidelights and stern light configurations, which makes B the correct answer.
