Under the U.S. Aids to Navigation System, red buoys indicate the right side of a channel when entering from the open sea, following the "red right returning" rule. These buoys are typically cylindrical and may be numbered with even numbers. They serve to guide mariners safely through navigable waters and are part of a comprehensive system to enhance maritime safety. Additionally, red buoys may also display a flashing red light at night for increased visibility.
In the US, to my knowledge, the only regular aids to navigation to have white lights are Safe water buoys (Entrance buoys) & range boards. Private aids to navigation may have white lights also. More to follow.
In U.S. coastal waters, cone-shaped even-numbered nun buoys are colored green. They are used as navigation aids to indicate safe passage and are typically found on the right side of a waterway when entering from the sea. These buoys are part of the lateral system of navigation aids established by the U.S. Coast Guard.
Navigation aids are such items as map, compass, gyroscope, and today items such as a GPS system.
A tidal basin is typically marked by a yellow buoy. This color indicates areas where tidal conditions may affect navigation and is part of the U.S. Aids to Navigation System. Yellow buoys can signify various marine features, including tidal basins, but it's essential to refer to local navigation charts for specific meanings.
Fixed obstructions are marked by aids to navigation, such as buoys, beacons, and markers. These aids help to indicate the presence of the obstruction and provide guidance to mariners to navigate safely around them. Additionally, charts and electronic navigation systems also display fixed obstructions to help vessels avoid them.
