Which small passenger vessel(s) is/are NOT required to carry a Category 1 406 MHz EPIRB?

Correct Answer: Option D — All of the above

Per 46 CFR 117.64, EPIRB requirements apply to vessels operating on the high seas. Vessels restricted to lakes, bays, sounds, rivers, or within three miles of the coastline are generally exempt from carrying a Category 1 406 MHz EPIRB, as these waters are considered sheltered or near-coastal.
