Question 251 Deck Safety

The correct answer is A) 1 watt or less. The normal operating power for ship-to-ship communications on channel 13 is 1 watt or less, as per the FCC regulations for VHF marine radio communications. Channel 13 is designated for navigational communications between ships, so a lower power output is required to avoid interference with nearby vessels. The other options (5 watts, 10 watts, and 20 watts) would be too high for the intended use of channel 13 and could potentially cause issues with nearby ship-to-ship communications.
