n the one hand, I’m sorry to report that the

U.S. Coast Guard has made little visible

progress toward implementing Rescue

21, the new search-and-rescue communications

system that will, eventually, unleash the poten-

tial of DSC-VHF radios. On the other hand (this

comes as a real surprise), the reappearance of coastal

marine VHFoperators just may induce a lot of sailors

to finally get their MMSI numbers and to properly

interface their DSC-VHF radios with their GPS re-

ceivers. The new crop of reasonably priced full-

feature Class D DSC receivers with big, easy-to-read

LCDs and features like built-in fog horns are also

very seductive. Of course, there’s a lot more than

just VHF modulating the air waves. This year we

have live weather data coming down from Sirius

radio satellites, several new short-range wire-

less products for man-overboard retrieval, and ever

more clever ways to enjoy cellular, Internet, and

TV service farther offshore.

Sea Smart

Sea Smart is what you get when Sea Tow, which

already had a national call center and a well-de-

veloped internal VHF dispatch system, ob-

tained access to all the ship-to-shore channels

and infrastructure that Maritel bought up dur-

ing the 1990s (and then shut down in a spec-

tacular flame-out). Unlike Maritel, Sea Smart makes

modest claims for its service, but it will certainly

include coverage well beyond cellular range in

many areas. Live Sea Smart operators, easily con-

tacted with a DSC-VHF radio, can not only

patch through a phone call, but can also help with a marine problem. A subscrip-

tion—$144 per year for Sea Tow members, $204 for nonmembers—includes an

unlimited number of calls, as well as access to a password-protected Web site where

you or a family member can track your boat (as shown). The service is now ac-

tive along the New Jersey, New York, and Connecticut shores, as well as the west

coast of Florida. The entire U.S. coast is slated for coverage by November 2007.
