Subject: RE: [worldcruising] relying on GPS

When sailing near the equator I was worried by the constant display of
lightning around the boat.
I lightning hit near the boat all electrics could be wiped out. So in
addition to my built in GPS with an external aerial I carried a spare hand
held GPS in the abandon ship bag along with the hand held VHF. I also had a
hand held GPS stored in a metal tool box to try and avoid lightning damage.
I did have a plastic Davis sextant and tables just in case all else failed
though.

Perhaps the operating systems used for the GPS satellites themselves are
using Win 95 or Win 98? I would strongly urge you to reconsider alternatives
to relying solely on GPS for navigation.
Just some food for thought.

Subject: [worldcruising] Electronic Charts systems
Hi,
As we know there are two common ways in having an electronic chart
plotter on board. One is based on using a PC or laptop and the other
based on a dedicated chart plotter.
My experience with the failure in Win 95 and Win 98 is making me very
nervous on using just the software on a laptop.
What is the reliability of the dedicated chart plotters using C-Map?
My intention is not to rely only on the electronics, so I will carry
some paper charts however I am not planning to use a sextant based on
my experience on GPS system
Appreciate any inputs.
