33 Chapter 4 ■ Visual Distress Signals Visual Distress Signals (VDSs) allow vessel operators to signal for help in the event of an emergency. VDSs are classified as day signals (visible in bright sunlight), night signals (visible at night), or both day and night signals. VDSs are either pyrotechnic (smoke and flames) or non-pyrotechnic (non-combustible). ◆ Vessels on federally controlled waters must be equipped with U.S. Coast Guard– approved visual distress signals. All vessels, regardless of length or type, are required to carry night signals when operating between sunset and sunrise. Most vessels must carry day signals also; exceptions to the requirement for day signals are: • Recreational vessels that are less than 16 feet in length • Non-motorized open sailboats that are less than 26 feet in length • Manually propelled vessels ◆ VDSs must be U.S. Coast Guard–approved, in serviceable condition, and readily accessible. ◆ If pyrotechnic VDSs are used, a minimum of three must be carried in the vessel. Also, pyrotechnic VDSs must be dated and may not be carried past their expiration date. ◆ The following combinations of signals are examples of VDSs that could be carried on board to satisfy U.S. Coast Guard requirements: • Three handheld red flares (day and night) • One handheld red flare and two red meteors (day and night) • One handheld orange smoke signal (day), two floating orange smoke signals (day), and one electric light (night only) ◆ It is prohibited to display visual distress signals while on the water unless assis- tance is required to prevent immediate or potential danger to persons on board a vessel. Pyrotechnic Devices • Pyrotechnics are excellent distress signals. However, there is potential for injury and property damage if not handled properly. These devices produce a very hot flame, and the residue can cause burns and ignite flammable materials. • Pistol-launched and handheld parachute flares and meteors have many characteristics of a firearm and must be handled with caution. In some states, they are considered a firearm and are prohibited from use. • Pyrotechnic devices should be stored in a cool, dry, and prominently marked location. Non-Pyrotechnic Devices • The distress flag is a day signal only. It must be at least 3 x 3 feet with a black square and ball on an orange background. • The electric distress light is accepted for night use only and must flash the international SOS distress signal automatically. federally controlled waters Waters on which vessels must observe federal requirements, including VDS requirements; these waters include: • Coastal waters • The Great Lakes • Territorial seas • Bodies of water connected directly to one of the above, up to a point where the body of water is less than two miles wide Arm Signal Although this signal does not meet VDS equipment requirements, wave your arms to summon help if you do not have other distress signals on board.
