The correct answer is C) has berthing and galley facilities. The regulations require vessels operating outside of coastal waters to carry an automatically activated Emergency Position Indicating Radio Beacon (EPIRB) if they have berthing and galley facilities. This is because vessels without these amenities are considered more likely to be in close proximity to shore and thus have other means of communication and rescue available. The EPIRB requirement ensures that vessels venturing further offshore have a reliable way to signal their location in an emergency. The other options are incorrect because A) a workboat's EPIRB requirement is determined by the mother ship, not the workboat itself, and B) the lack of berthing facilities alone does not exempt a vessel from the EPIRB requirement.
