A vessel engaged in dredging displays specific lights to indicate its activity. It shows two all-round lights in a vertical line, with the upper light being white and the lower light being yellow. Additionally, it may exhibit a ball shape during the day to signify its dredging operations. These signals help other vessels identify its status and navigate safely around it.
A white light is the color of light that must be displayed on a vessel towing at night, I t must be displayed at 8.2 feet higher than the colored sidelights. It should have an all round white light visible for 2 miles.
The masthead light is typically white in color. It is displayed at the top of a vessel to indicate the presence of another vessel at night.
A vessel engaged in fishing
A vessel displaying sidelights, a sternlight, and two all-round lights in a vertical line is typically a power-driven vessel that is 50 meters or more in length. The two all-round lights indicate that it is engaged in fishing or another specific activity, such as towing or dredging. This configuration helps other vessels identify its activities and navigate safely around it.
Generally they are masthead light, port and starboard steaming light and stern light. Others may be displayed depending on the length of the vessel and what duties it is carrying out.
A sailing vessel under sail at night must exhibit red and green sidelights and an all-round white light when underway. The red light is displayed on the port side, and the green light on the starboard side, while the all-round white light indicates the vessel's presence and helps prevent collisions. This lighting configuration is essential for visibility and safety on the water.
If you encounter a vessel displaying only a visible white light, it is most likely a power-driven vessel that is underway. In this situation, rules of the road require that you keep to the starboard side and pass at a safe distance. Be cautious and keep a lookout for any other lights displayed by the vessel to determine their course and intentions.
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.
In darkness, a vessel displaying red and white lights indicates that it is a fishing vessel engaged in fishing activities. The red light typically signifies that the vessel is at anchor or restricted in its ability to maneuver, while the white light may be used to show that it is fishing. It is important for other vessels to exercise caution and maintain a safe distance from such vessels to avoid collisions.
sailer of a light fast vessel
The anchor light on a sailboat is typically referred to as an "anchor light" or "riding light." It is a white light that is displayed at the stern or at the top of the mast when the vessel is at anchor, signaling its presence to other boats. This light must be visible from all directions and is a key safety feature to prevent collisions during nighttime.
The characteristics of navigation lights on a power driven vessel includes sidelights, sternlight, masthead light, and all-round white lights. Navigation lights must be displayed from sunset until sunrise as well as anytime visibility is restricted.
