- A. One prolonged blast followed by two short blasts, at intervals of not more than 2 minutes
- ✓ One prolonged blast followed by three short blasts, at intervals of not more than 2 minutesCorrect
- C. Two prolonged blasts, at intervals of not more than 2 minutes
- D. One prolonged blast followed by three short blasts, at intervals of not more than 1 minute
Why B is correct
33 CFR §83.35(e) requires the last manned vessel of a tow to sound four blasts — one prolonged followed by three short blasts — at intervals of not more than 2 minutes. This signal is distinct from the towing vessel's signal of one prolonged and two short blasts prescribed by §83.35(c).
