The channel usage marked with an asterisk (*) are from tables in Icom IC-M2
and IC-M55 marine radio manuals, and are probably fairly "generic", and
subject to change in different jurisdictions. Other channel usage is from my
station licence for the Canadian West Coast, and from things overheard on the
air. "Your usage may vary."

Channels marked (CCG) or (USCG) are for Canadian or US Coast guard authorized
stations only.

Channel 70 is reserved for digital selective calling (DSC), part of the Global Maritime
Distress and Safety System (GMDSS). It must not be used for voice communications.

The letters under "area" mean:
I: International only (non-US) according to Icom
C: Canadian usage
A: American usage

Channels with an "A" suffix are simplex operation on the ship transmit
frequency of an international duplex channel.

Canada uses a "B" suffix to denote broadcast (one-way) use of the shore
transmit side of an international duplex channel. Channels 87B and 88B are used
internationally for AIS (Universal Shipborne Automatic Identification System).

There are no repeaters (as hams know them) in the marine service . If you
are willing to pay for a phone call, the telco might let you place a call
to another vessel on the same (or different) channel, and so get the effect
of a repeater.
