Visual distress signals (VDSs) allow vessel operators to signal for help in the event of an emergency.
Vessels on federally controlled waters, such as New Hampshire’s coastal waters, must be equipped with visual distress signals that are USCG–approved, in serviceable condition, readily accessible, and that must not be expired.
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
If pyrotechnic VDSs are used, a minimum of three must be carried in the vessel. Expired VDSs may be carried on board, but a minimum of three unexpired VDSs must be carried in the vessel.
The following combinations of signals are examples of VDSs that could be carried on board to satisfy USCG 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 VDSs while on the water unless assistance is required to prevent immediate or potential danger to persons on board.
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).
