![]() ![]() Two masthead lights in a vertical line – three of these lights if the tow (length of tow cable plus object being towed) exceeds 200 metres.Towing light (yellow light with the same characteristics as the sternlight).In the case of a power-driven vessel towing another vessel from its stern, the towing vessel must exhibit the following: The tow's navigation lights do not include masthead lights and are often much dimmer than those of the towing vessel. The towing vessel is usually more visible than its tow. To avoid this and to keep from getting caught on the towline (or worse), you must be alert for the special shapes and lights displayed by vessels towing barges, other vessels or objects. If a small craft were to strike the submerged towline, it could capsize and be run down by the barge. Often, the length of the tow is so great the towline hangs below the surface of the water and is nearly invisible. Tugs may be towing barges or other vessels on a long towline astern. ![]() Vessels less than 7 metres long are not required to exhibit anchor lights or shapes when anchored – unless in or near a narrow channel, fairway or anchorage, or where other vessels normally pass. Vessels that are at anchor and are less than 50 metres long must exhibit, depending on the time of day and visibility, an all-round white light or one ball where it can best be seen (see Figure 9-7). Power-driven vessels less than 7 metres long that can travel no faster than 7 knots may exhibit an all-round white light, and sidelights if practicable, instead of the lights required for power-driven vessels.įigure 9-1 Power driven vessels – Examples Power-driven vessels less than 12 metres long may, in addition to sidelights, exhibit an all-round white light instead of the masthead light and the sternlight (see Figure 9-2). Power-driven vessels less than 20 metres long may have the sidelights placed in front of the forward masthead light (see Figure 9-1). A second masthead light may also be exhibited abaft of (behind) and higher than the forward one. Power-driven vessels up to 50 metres long must exhibit a masthead light forward, sidelights and a sternlight when underway. verify that the lights are correctly mounted.make sure your vessel is equipped with the proper lights for its size and purpose and.show navigation lights from sunset to sunrise and during periods of reduced visibility.Navigation lights must meet Collision Regulations requirements. The navigation lights on other vessels can help you tell the direction they are moving or whether they are at anchor or engaged in some other activity. Vessels near you will make decisions based on the information your lights provide. Navigation lights help prevent collisions by making your vessel and its direction of travel more visible to others. As a result, you must be aware of all Collision Regulations requirements, not just those applicable to your vessel. If you operate a vessel, you need to know how different vessel types, such as fishing vessels and seaplanes, will act or react in all situations. IMPORTANT: Throughout this guide, including in this chapter, the information provided is general and not all situations are included. ![]()
