2) a yellow all-around light

Answer 1

For an 18-foot powerboat underway, the required navigation lights are red and green sidelights and a white stern light.

Step-by-step explanation:

For an 18-foot powerboat underway, the required navigation lights are red and green sidelights and a white stern light. Boats power-driven or sailing under power at night are required to display these lights to ensure they can be seen by other vessels and to indicate their size and direction.

The sidelights are red on the port side and green on the starboard side, providing other vessels with a means to determine the direction the boat is traveling. The stern light, which is white, should be visible from behind the vessel. This combination of lights is essential for maintaining safety on the water and preventing collisions.
