Re: [Paddlewise] GPS accuracy

Are you seriously proposing that a fix accuracy of 25 feet or so will/could
be a factor in a life or death situation?

For my amusement, using some freeware moving map software interfaced to my
old Garmin GPS-38, I laid out a route, uploaded it to the GPS and followed
it while paddeling last Sunday. The accuracy of the process was dazzling!
Could I have navigated as well with a compass and current  tables... sure.
My point is that we spend to much time with trivia and not enough with the
important things.

In my opinion the single most important thing(s) for ANYBODY involved with
small boats are to make dammed sure what kind of weather lies in the
immediate future and the state of the tides and currents.  Everybody should
carry AND USE some kind of radio which will receive the local marine
forecast!

>From bitter experience I learned to resist the urge to go if the weather
will be questionable (for the type of boat you are using.)  I finished read
Matt Booze's book describing kayaking disasters.  Ignoring or being ignorant
of impending bad weather is a thread which weaves through to many of the
incidents described.

Incidentally, your remarks about the Sound are totally correct.  I generally
navigated )with great success) with hand bearing compass and depth sounder.
