Some Boats: Radar is an excellent means of marine navigation and is used on vessels of all sizes, down to some boats of about twenty feet in length. Although not installed on all recreational some boats, its capabilities and limitations should be known to all boaters for their own safety when cruising on waters navigated by radar-equipped vessels.
The prudent skipper will have a thorough knowledge of the Rules that apply to all types of some boats and ships that operate on waters that he or she uses. The official text of the Rules are in the Coast Guard publication Navigation Rules, International-Inland, which is available at most chart outlets. The major requirements that apply to recreational some boats are listed briefly here.See Also Non-commercial Boats Used:Three types of radio systems are used aboard boats; two of these are designed and licensed specifically for marine use. The third is the Citizens Band radio system.
VHF-FM marine radios are considered to be the prime system for marine communications over distances of up to about 30 miles. There are 50 channels in the VHP band dedicated to various marine uses in U.S. waters. Some are for communications between vessels, and these are divided between commercial and non-commercial boats used (recreational) craft. Several are for special uses, such as navigational safety and direct bridge-to-bridge communications (see below). Some are for the exclusive use of the Coast Guard and other governmental entities. Others are for linkup with shoreside telephone systems. There also are channels for contact with shoreside facilities such as marinas and yacht clubs.
VHP radios may be physically installed and electrically connected by the Boat owner or any person. An SSB set should be installed by a qualified technician and checked out by a person holding an FCC Commercial Operator License. Radio installations on gasoline-powered boats will generally require some form of ignition-noise suppression or shielding: this is a job for a technician. With regard to maintenance, an unlicensed person is limited to matters that will not affect the quality of the signal on the air. For example, he can replace a blown fuse, but cannot make internal repairs.
On The Other Hand See Boats Ply:There are two electronic navigation systems available to skippers of boats ply as well as to navigators of large ships. The cost, size, and power requirements of these systems have now been reduced to the point that they are feasible options for boats ply of almost any size. The newer, and now the more widely used, system is the Global Positioning System (GPS). Also used by many boaters is Loran, an older system still in operation. Almost all new installations, however, are GPS.
To receive VSC approval, all recreational boats ply used on coastal waters or the Great Lakes must have a minimum of three Coast Guard-approved day and night visual distress signals that have not reached their expiration dates. Some signals, such as red flares, can serve for both day and night requirements. boats ply operating on inland waters should have some means of making a suitable day and night distress signals.
