My Garmin plotter gives me the local time of day. I think it knows where
you are from the lat / lon and uses that number.

Um - wouldn't the GPS pick up the UTC time from the satellite and
convert it using the local offset you input when you first set it up?

Just curious.


No, for some reason it doesn't "hold" the offset, or it didn't when I
tried that a few years ago. I suppose I could try again, assuming I did
something wrong when first setting it up. But I do recall that I tried it
a couple of times, it didn't hold, and I gave up on that feature.

Oh...another reason: I rarely use the GPS chartplotter on Yo-Ho these
days. I know all the throttle-trim settings I need now, and most of my
fishing is at locations I arrive at by "sight," or where my fishfinder
indicates "activity." There's not a lot of bottom structure to look for in
Chesapeake Bay, so keying in exact points is not really necessary in order
to find fish. As an example, if I head straight across the Bay from my
usual starting point, I know that as soon as the depth finder indicates a
particular drop-off on the "other side," I've reached flounder territory,
and I need to follow that drop off north and south.

On my trip to the Chesapeake Bay Bridge Tunnel, a run of about 115 miles,
I simply stayed in the middle of the Bay and navigated by sight. You've
been down here, right? Most places you can see both shores of the Bay as
you head north or south.

The watch is important. There are a couple of spots where tidal data is
significant for fishing.
