Visual Distress Signals: Read the Approval and Use Case
A guide to day, night, pyrotechnic, and non-pyrotechnic visual distress signals based on Coast Guard requirements.
Determine What The Trip Requires
The Coast Guard's federal guide explains which recreational vessels operating on coastal waters, the Great Lakes, territorial seas, and connected waters must carry approved visual distress signals, along with listed exceptions. State requirements may add to the federal baseline.
Use the current official table for the boat and trip. Do not copy a checklist from a different vessel size, water body, or day-only operation.
Separate Day And Night Approval
Orange smoke and the approved orange distress flag are day signals. Red pyrotechnic flares may have day-and-night approval depending on the device. An approved electronic visual distress signal device is a night signal.
Read the Coast Guard approval and service instructions on each product. A bright flashlight or unapproved strobe may be useful additional equipment but should not be counted as a required approved signal unless the label says it qualifies.
Inspect Access, Condition, And Dates
Required signals must be readily accessible and in serviceable condition. Pyrotechnic devices used to meet the requirement must be within their marked service life, and the Coast Guard recommends cool, dry storage in a clearly marked watertight container.
Inspect electronic devices, batteries, flags, launchers, and packaging according to their instructions. Keep expired pyrotechnics separate from the current set and follow local disposal rules.
Learn Use Without Creating An Emergency
Read the instructions before departure and brief the crew on location and safe operation. Never fire a distress signal except in an emergency or an authorized training setting.
Visual signals complement radio, beacon, and float-plan procedures. They help searchers see a boat or person; they do not transmit the position, vessel identity, or nature of distress.
