A previous post I was reading got me thinking about this :::::::

The GPS, say a Garmin ,, models like the 76. I know that if you have a lap
top and MAPTECH Offshore Navigator CD which comes with the chart book ..
whew ... anyway ,, the Garmin GPS will work as a receiver for position the
the Offshore Navigator software will act as the chart ,,, so you will know
where you are on the chart and all.

I like the idea. I have MAPTECH charts and the CD. I can get a Garmin GPS
.. But and here is the big BUT;;

What about the Laptop? Where would a sailboat keep it so it didn't get wet?
What laptop? What is a good model to use for this purpose?

I'm sure one of you cruising sailors has done this ... could you explain how
it works, what computer you use, where you keep the computer when on the
water, and generally how the whole process works for you.

Thanks
