Watercraft navigation lights must permit other vessels to determine the type and relative angle of a vessel, and thus decide if there is a danger of collision. In general, sailing vessels are required to carry a green light that shines from dead ahead to 2 points (22 + 1 ⁄ 2 °) abaft [note 1] the beam on the starboard side (the right side from the perspective of someone on board facing ...
The Channel lightvessel was established in 1979 as part of the Off Casquets Traffic Separation Scheme (TSS), introduced following the 1978 grounding of the Amoco Cadiz. [3] The lightvessel was intended to clearly define the TSS, as such schemes were at the time a new feature, rather than marking a physical hazard to navigation.
The appropriate lights may also be displayed during the day at times of restricted visibility or other necessary circumstances. [3] Vessels under 7 meters are generally not required to display day shapes even if they are required to display lights at night. [4] A square black flag displayed over the ball may be used as a distress signal. [5]

In the 1930s, "crewless lightships" were proposed as a way to operate a light vessel for six to twelve months without a crew. [8] The first lightvessel conversion to solar power was made in 1995, and all vessels except the '20 class' have now been converted. The '20 class' is a slightly larger type of vessel that derives its power from diesel ...
Leading lights, also known as range lights in the United States, are a pair of light beacons used in navigation [2] to indicate a safe passage for vessels entering a shallow or dangerous channel; they may also be used for position fixing. At night, the lights are a form of leading line that can be used for safe navigation. The beacons consist ...
