Displays the location of marine beacons for the State of Hawaii as recorded on NOAA nautical charts. While buoys float at the surface of the water, beacons are fixed to the sea bottom. Both are used as aids to navigation (ATONs) to indicate traffic channels, to warn against potential dangers, or for other navigational purposes. Some include lights or radar reflectors to make them visible at night and in conditions of reduced visibility. In the IALA B maritime buoyage system (North and South America), red lateral markers have even numbers and should remain on your right when returning from sea ("red, right, returning") while green lateral markers have odd numbers and should remain on your left.
