Towing & Ship-Assist · Communications
When arranging a meeting or passing with another vessel, the preferred initial method on most U.S. inland waters for towing vessels is:
- AEmail
- BBridge-to-bridge radiotelephone (VHF 13), backed up by whistle signals as required✓ Correct
- CHand flags only
- DNo communication is needed
Explanation
Towing vessels routinely arrange passings by bridge-to-bridge radio on VHF 13, which is faster and clearer than whistle signals alone. The Rules still require/allow whistle signals, and an agreement reached by radio should be consistent with the maneuvering signals.
