When I fitted out my new 1992 Almar Sounder 24, I installed a Si-Tex Loran C
chart plotter. 5 years later (1997) that was still my primary navigating
device. Repeatedly accurate to 50 feet and usually much closer. I had a
Garmin hand held GPS hard wired in at the helm station, but I only used it
in fog when I needed quicker updates to waypoints. Mainly relied on radar
even then. That was operating out of Sequim Bay, WA into Juan de Fuca,
Admiralty Inlet and the Islands. If I were still there, still had the boat
and if the gov is still sending out the signals, I'd probably still be
relying on the Loran C. Always used TDs too, never L&Ls. But then that's
local knowledge coupled with what you're comfortable with, what you learned
on and in one's home waters. My next boat has GPS/WAAS interfaced to an
Electronic Navigation System. It's like driving a train...just stay between
the dotted lines on autopilot and accurate to 8 feet. Rocky passages are no
problem, two dimension-wise.
