Which is a requirement for any person maintaining a listening watch on a bridge-to-bridge radiotelephone?

Correct Answer: Option A — speak English

33 CFR 26.04 mandates that bridge-to-bridge radiotelephone communications must be conducted in English. This requirement ensures clear, standardized communication between vessels to prevent misunderstandings during close-quarters situations or navigation in restricted waters, which is critical for maintaining safety and preventing collisions in US navigable waters.
