BOTH INTERNATIONAL & INLAND Which statement is TRUE regarding equipment for bell and gong signals?

Correct Answer: Option B — Manual sounding of the signals must always be possible.

Annex III, Section 2 of the COLREGS and Inland Rules requires that all prescribed sound signals must be capable of being sounded manually. While automatic systems are permitted and common on larger vessels, the capability for manual operation is a mandatory safety requirement for all vessels.
