Boat Signaling Devices: Stay Safe and Be Seen
Effective signaling equipment can be the difference between being seen and being stranded. The U.S. Coast Guard (USCG) requires all boats operating in U.S. waters to carry approved visual distress signals (VDS). These devices help boaters attract attention during emergencies such as breakdowns, collisions, or man-overboard incidents.
At Wholesale Marine we carry a full range of boat signaling devices including handheld flares, aerial flare launchers, distress flags, and electronic visual distress signals. Many boaters are now switching to eVDSD lights, which use bright strobe LEDs to meet Coast Guard standards without the need for pyrotechnics or replacements.
Alongside visual signals, every vessel must also have a sound signaling device such as a marine air horn or whistle. These are used to alert other vessels in low visibility or confined areas and are mandatory for boats over 12 meters in length. For added safety, pair your signaling equipment with a boat alarm system to detect hazards early and ensure your crew can respond quickly.
How Long Do Boat Flares Last?
Traditional pyrotechnic flares typically expire 42 months (3.5 years) from their manufacture date. Always check the expiration date on your flares and store them in a dry, easily accessible location. Expired flares can still be kept as backups but should not replace a valid signaling device.
If you prefer a long-lasting, maintenance-free option, consider an electronic visual distress signal (eVDSD) - they meet USCG standards, require no replacement, and are rechargeable or battery-powered.
Proper Storage and Maintenance
Keep all boat signaling devices in a waterproof container or dedicated storage locker away from direct sunlight. Ensure every passenger knows where the equipment is located and how to use it. Conduct seasonal checks to confirm that flares, horns, and lights are operational and up to date.
Frequently Asked Questions About Marine Signaling Devices
What visual distress signals are required on boats?
All boats operating on coastal waters, the Great Lakes, or connected waters must carry U.S. Coast Guard-approved visual distress signals - either pyrotechnic flares or approved electronic distress lights (eVDSD).
How long do boat flares last?
Flares expire 42 months after manufacture. Check expiration dates regularly and replace them to remain compliant.
Can I replace flares with electronic distress lights?
Yes. eVDSD lights are now USCG-approved alternatives to pyrotechnic flares for most recreational vessels. Always confirm your device carries the proper certification mark.
Where should signaling devices be stores?
Store signaling equipment in a cool, dry. and easily accessible area. Everyone onboard should know here it is and how to use it during an emergency.
