Which vessel is required to carry a Category I, 406 MHz EPIRB installed to automatically float free and activate? (small passenger vessel regulations)

Correct Answer: Option C — A vessel operating beyond 3 miles from the coastline of the Great Lakes.

46 CFR 180.64 requires a Category I, 406 MHz EPIRB for vessels operating on the high seas or beyond 3 miles from the coastline of the Great Lakes. This equipment must be installed to automatically float free and activate upon immersion to ensure distress alerting in open water environments.
