When underway, a power-driven vessel displays a combination of navigation lights: a white masthead light at the front, sidelights (green on the starboard side and red on the port side), and a white stern light at the rear. The masthead light is visible from ahead and extends 225 degrees, while the sidelights are visible from the side and ahead. The stern light provides visibility from behind. These lights help ensure the vessel is seen and identified by other vessels during nighttime or low visibility conditions.

On power driven vessels how should navigation lights be?

On power-driven vessels, navigation lights must be displayed in accordance with the International Regulations for Preventing Collisions at Sea (COLREGs). Typically, these vessels should show a white masthead light, red and green sidelights, and a sternlight when underway. The lights must be visible from specific angles and distances to ensure safe navigation and to signal the vessel's status to others. Proper use of navigation lights is crucial for preventing collisions during both day and night.

What determines the navigation lights you are required to display on a vessel?

The navigation lights required on a vessel are determined by its size, type, and the conditions under which it operates, as outlined in the International Regulations for Preventing Collisions at Sea (COLREGs). Vessels are classified into categories such as power-driven, sailing, and fishing vessels, each with specific light configurations. Additionally, the operational context, such as whether the vessel is at anchor or underway, also influences the required lighting. Compliance with these regulations ensures safety and visibility on the water.

On power driven vessels what are the navigation lights?

Power-driven vessels must display specific navigation lights to indicate their presence and movement at night or in low visibility. Typically, they show a red light on the port side (left), a green light on the starboard side (right), and a white stern light at the rear. Additionally, a white masthead light is required, visible from ahead and at a distance. These lights help other vessels identify the type and direction of the power-driven vessel.
