EPIRB
In a discussion about piracy, someone brought up the subject of EPIRBs. What is an EPIRB? There are far too many acronyms in the world today, that I really don’t need another one. For example, when someone writes “BBB” in a chart, are they referring to “blood-brain barrier” or a “bundle branch block”? There’s a big difference! Depending on context, “ASA” can refer to either acetylsalicylic acid or the American Sailing Association.
An EPIRB is simply an emergency position-indicating radio beacon. Nothing complicated there.
