Harry,
Why don't you just use the built in battery, and then recharge it when you
get home from your day of boating?

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.

Smithers, laptop batteries may give you 3 hours or so of power. You would
need to plug it into a reliable power source when out boating.

Harry, I would think that you would be OK using the boat battery if you
never had problems using the car battery.

For $80 to $100 you can buy adaptors specially designed for auto and boats.
If my Notebook was new, I would probably buy it. If it was 3 to 4 yrs old,
I would assume the laptop is almost obsolete and say the money.

Just buy a $20 140 watt inverter and plug in the AC charger to the inverter.
Have used that for years with different laptops. No problems. Went this
way in about 1996 when it was $200+ for a 12 volt charger for the Dell
laptop.

Exactly. The notebook's battery charger will isolate any spikes and the
notebook's battery will compensate for any voltage drops.
