It's called a lantern.
A stern light is a white navigation light on the rear (stern) of a watercraft. It helps other vessels determine the direction the boat is headed in low visibility conditions or at night. The white light indicates the boat's position and helps prevent collisions on the water.
A boat's stern light is white. It is located at the rear (stern) of the vessel and is used to indicate the boat's presence to other vessels. The white light must be visible from all directions, ensuring safety and visibility during nighttime navigation.
The white light on a powerboat is typically located at the stern or rear of the vessel. It serves as a navigation light to indicate the boat's position and direction to other vessels at night or in low visibility conditions. This light must be visible from a specific distance and angle to ensure safe navigation. In addition to the stern light, powerboats also have red and green navigation lights on the bow to indicate their port and starboard sides, respectively.
On a powerboat, the white navigation light is typically located at the stern, or rear, of the vessel. This light is positioned so that it is visible from behind the boat, ensuring that other vessels can detect its presence when approaching from the rear. It is part of the required navigation lights for nighttime operation, helping to indicate the boat's position and direction.
A red light displayed on the stern of a boat indicates that it is operating at night or in low visibility conditions. According to maritime navigation rules, vessels are required to show a red light at the stern to signal their presence and direction to other boats. This helps prevent collisions by allowing other mariners to identify the boat's orientation and movement. The stern light is typically visible from behind the vessel and complements other navigation lights displayed on the boat.
On a powerboat, the white navigation light is typically located at the stern (rear) of the vessel. It may be mounted on the transom or on a pole extending from the rear. This light is used to indicate the boat's position and direction to other vessels, ensuring safe navigation during nighttime or low visibility conditions.
A boat's sternlight is typically white. It is positioned at the stern (rear) of the vessel and is used to indicate the boat's presence to other vessels from behind. The white light must be visible from a specific distance, ensuring safety during nighttime navigation.
A white light used by itself which can be seen in all directions is the anchor light, which means you are anchored. A white used in conjunction with bow lights (green and red) are your navigation lights. The white light indicates your stern ( back of boat). If all you can see is the white light, a boat is either anchored or underway going away from you.
The white stern light on sailboats is a navigation light that is required by maritime regulations. It is positioned at the stern (rear) of the vessel and serves to indicate the boat's presence and direction to other vessels at night or in low visibility conditions. The light must be visible from a certain distance and helps prevent collisions by allowing other boats to determine the sailboat's orientation and movement. In combination with other navigation lights, it plays a crucial role in maintaining safety on the water.
If you see a red light, a green light, and a white light on another boat, it indicates that the boat is facing you and is likely under way. The red light signifies the port (left) side, the green light signifies the starboard (right) side, and the white light is typically a stern light. This configuration helps determine the boat's orientation and direction of travel. Always maintain a safe distance and be aware of navigation rules.
Properly, it is a white light, and elevated higher than the red/green lights on the front of the boat.
This boat must have a white mast head light & a white stern light. Also, it must have a green running light on the right (starboard) side of the boat & a red running light on the left (port) side of the boat. The red & green lights may be mounted on the sides of the boat (international regs.) or nose of the boat if the boat is basically used on rivers or lakes in the U.S. (called: river navigation lights).
