I would advise against using a computer as the primary GPS. And a "plug-in" GPS (one
that can't work alone) is even worse. At the very least, get a small handheld that can
stand alone, and connect it to the computer with a data cable.

Although I have a number of computer charting programs loaded, and my boat is wired
appropriately, I hardly ever use the computer underway. A small mapping handheld (I have
an older GPSMAP 175, today I'd get a 76 or 176) plus a chartkit suits my need much better.
I have friends that like using the computer, and have it wired to the autopilot, so the
boat will "follow the mouse," but they have an enclosed center cockpit 41 foot ketch, and
the computer is right down the companionway. Plus they have another GPS at the helm.

The last time I researched low end GPS units, I decided the Garmin GPS 72 was the "best
buy" because it came with the cables that would be needed. I don't think this is still
true - whatever you get, consider the "total cost" of all the accessories you'll want.
The 72 is nice because it has a large display, its waterproof and floats, and has a navaid
and tide database.

I have a nice laptop running Windows XP with a nice big screen.

Can anyone recommend a GPS plug-in for my laptop that comes with sailors
software? It should have all the good stuff like VMG.

I've been away from sailing for several years. If this is not a good choice
then can someone recommend a reasonable cost handheld or deck-mounted GPS
system?

Thanks,
