Emergency position indicating radio beacons
An emergency position indicating radio beacon (EPIRB) is an electronic device that, when activated, assists rescue authorities to locate those in distress.
All recreational vessels heading out more than two nautical miles from the coast are required to carry an approved 406 Mhz EPIRB. However, it is recommended that all vessels carry a GPS-enabled EPIRB.
Have your safety equipment in a waterproof (and preferably buoyant) safety grab bag in an easily accessible position on the boat, not stuffed into the bow locker.
Paddlers may prefer to carry a personal locator beacon (PLB) because they are smaller. PLBs should be attached to the paddler's lifejacket so they can be kept upright and out of the water if you fall in. PLBs are not considered a substitute for EPIRBs when adhering to State marine carriage regulations. Solo boaters may wish to carry a PLB in addition to an EPIRB.
