Which navigation lights are required for an 18-foot powerboat?

For an 18-foot powerboat, the required navigation lights include a green light on the starboard (right) side of the vessel, a red light on the port (left) side, and an all-around white light that is positioned higher to indicate the vessel's presence.

This configuration of lights is essential for safe navigation, especially during nighttime or low visibility conditions, as it allows other boaters to determine the direction in which the powerboat is moving. The green light indicates the right side, while the red light indicates the left side, ensuring that if another vessel sees the lights, they can ascertain the orientation and course of the powerboat. The all-around white light provides visibility from any direction and signals that the vessel is underway.

This lighting setup conforms to the International Regulations for Preventing Collisions at Sea (COLREGs), which establish specific requirements for different sizes and types of vessels to enhance maritime safety.
