Channel 13, and 16
I believe on the Chesapeake Bay and other areas, it is rather important that you listen, as I do to both channels 13, and 16. All freighters, tugboats, and most commercial traffic will be trying to contact you on channel 13. Likewise Drawbridge operators. "16" is your emergency traffic channel and should be left to that task. However, if you want to know what the intentions of that tugboat pushing the barge abt. a mile or so ahead of you is, you had best contact him on 13. He'll tell you that you best alter course, or he'll pass you on one or two whistles, and if you ask, will pass on what traffic is behind him, the weather conditions he's just been thru, etc. Very courteous people these commercial folk. Also importantly, military vessels can be contacted on channel 16, but communications must be very brief, and/or switched to another channel. This is very true around the Norfolk area, where you normally will not get a reply on channel 13. Yes, it is very annoying to hear boaters not using the radio properly, and know when you hear that happening, the improper use indicates they probably don't even know the rules of the road, let alone proper radio usage. This is rather worrysome when you're traversing a narrow waterway and the source of that improper use is running right next to you. Makes you wonder what he/she's going to do next. On the Chesapeake bay, channel 9 is now considered the calling channel, as oppossed to some other areas of the country that still use 16. If you happen to see my Hunter 34 "Scotch and Water" on the Bay, please "holler" out!
