[alberg30] GPS mount

[Michael Grosh]

From: "Michael Grosh" <mgrosh at shore.intercom.net>

Both the GPS and the DGPS units I have used consistently show .2-.3 knots
when I am tied up to a dock. But, when I actually am underway, it's
indicated speed appears to be much more accurate than what I can calculate
by other means-it gives extremely accurate ETA's to specified waypoints, for
instance. I just don't know what the deal is with the at dock underway
speed.

I have a paddle wheel knotmeter on Checkmate. If I was to do it over again,
I would go with the GPS. I have spent more on a  replacement paddlewheel
than what GPS units now go for.

I was watching the readout the other day-this thing reads out lat/long down
to 1/1000 of a minute. I was moving at about 6.5 knots, the GPS updates
itself 1/sec.and the 1/1000 column was skipping digits (2,4,6,8,...)I don't
know what that breaks down to in feet, but it's not very much.
