Which channel is utilized for the required bridge-to-bridge watch?
• Bridge-to-bridge radiotelephone regulations in 33 CFR Part 26 • Difference between distress/safety calling channels and navigational/bridge-to-bridge channels • Which channel is used for collision avoidance and passing arrangements between vessels in U.S. inland waters
• Ask yourself: Which channel is specifically designated for making passing arrangements and navigation-related communications between vessels, especially in restricted waters and near bridges? • Which option is actually a digital selective calling (DSC) channel used to set up calls, rather than to conduct voice conversations? • Which channel is required to be monitored for distress, safety, and calling, and which is for bridge-to-bridge (navigation) communications?
• Identify which choice is the DSC channel (data, not voice) and eliminate it as a bridge-to-bridge watch channel. • Recall from 33 CFR Part 26 which VHF channel number is specified for bridge-to-bridge radiotelephone watch in most U.S. inland waters. • Distinguish between the general distress/calling channel and the specific navigation/bridge-to-bridge channel used for maneuvering and collision avoidance.
