I just got in DeLorme's new Street Atlas 2006 with the GPS puck for my
laptop, and I'm going to order some inexpensive NAV software right after
the first of the year. My current laptop is a four year old IBM T23,
which has been more than sufficient for my use while traveling. It has a
12V "cigar lighter" adapter/inverter box, which I have used without
incident on cars and boats. I'm assuming this device is sufficent to
"clean" that raw boat battery power so I don't fry the laptop. I haven't
had any problems with 12V power glitches so far, but I don't know if I'm
walking on the wild side here.

===================================

It will probably be fine but if you'd like an extra layer of isolation
go down to West Marine and buy one of their little $40 inverters with
the lighter plug built in. I've used a variety of them in cars,
boats, etc. with no problems at all, and they are not specific to any
one type of laptop. You can also use them to power a small reading
light, TV, DVD player, HiFi or anything else drawing less than 100
watts or so.
