A
VHF radio is a very important safety tool. We, at Sea Tow, recommend
that every boater who is venturing out into navigable waters have a fixed-mount
VHF installed on his or her vessel. In the event of an emergency,
boaters in your immediate area can hear your calls - as well as the Coast
Guard and other local authorities. A cell phone only provides one-on-one
communication while a VHF can be heard by many. If you are considering
the purchase of a new VHF radio, we would suggest that you get one that
is DSC capable. The Coast Guard, at this time, is NOT monitoring
the DSC channel (channel 70). They will begin upgrading their VHF
system in 2003 and are scheduled to have the entire system completed by
2006. |

A major improvement
in VHF technology is DSC or Digital Selective Calling. DSC
capable radios permit, among many other features, a "touch-of-a-button"
emergency call that is transmitted to all other DSC radios in
the area automatically and includes your position information
(when interfaced with a GPS), your unique MMSI (Maritime Mobile
Service Identity) number and can even transmit the type of distress.
If another vessel's DSC radio is connected to a compatible chart
plotter, your position will be displayed as an icon on the chart
plotter's screen, showing distance and heading to get to you.
When the Coast Guard does initiate their DSC system, an emergency
call that they receive can be interfaced with the MMSI database
and your personal information quickly retrieved. |
|
An additional Benefit
to DSC technology is the ability to contact another vessel directly
through the use of its MMSI number. This will help reduce
the congestion that currently exists on Channel 16. You'll
be able "dial direct" to other vessels in your area.

Sea
Tow has been authorized by both the U.S. Coast Guard and the
Federal Communications Commission to issue MMSI numbers to vessels
that are not
required by law to carry a radio, and do not make international
voyages or communications. Sea Tow is responsible for relaying
the MMSI registration information to the U.S. Coast Guard for
search and rescue purposes. The agreement between the
USCG, the FCC and Sea Tow is limited to registering DSC radios
on recreational vessels only - those not otherwise required
to have an FCC ship station license ("voluntarily equipped").
Vessels required to have a radio on board should obtain an MMSI
from the FCC.
