FWIW, John Neal comments in his cruising book that he has used common
desktop computers on his boat for years without trouble.

OK

Well reason Im asking is cause a good friend and his
wife just sold EVERYTHING and drove down to Florida and
bought a 32' sail boat and taking a year to "cruise"

They started planning three years back for this by
taking all kinds of classes, etc

Anyway..... I don't own a boat and don't know anything
abt sailing... but his adventure has me fascinated!

As a result Ive posted a few messages on the "nuts and
bolts" for doing such a thing
