The Coast Guard recognizes that many vessel owners choose to place of decorative lights onboard their vessels during the Holiday season. The Coast Guard strongly reminds vessel owners not to illuminate such lights during routine navigation unless operating in a Holiday boat parade or when the vessel is secured dockside. This issue was highlighted during a recent casualty whereby the owner of a passenger vessel had installed decorative Holiday type LED (Light Emitting Diode) lighting around the periphery of the vessel. The LEDs were contained in a clear flexible hose and securely attached. Near the bow of the vessel the lighting was adjacent and slightly above the port and starboard navigation lights. At night this installation, can impair the “distinctive character” of the navigation lights as set out in Rule 20 of the Navigation Rules. (See photo in attachment.)
Additionally, Rule 22 of Navigation Rules states that vessel sidelights have a two mile range for vessels 12 meters or more in length but less than 50 meters in length. In this particular casualty a side light navigation fixture was found installed on the passenger vessel that was stamped 1 nautical mile vice two miles. Vessel owners and operators and marine inspection personnel should ensure that the proper navigation lighting fixtures are installed, that all components operate correctly and that regulatory requirements with respect to Navigation Lighting are met.
