Just to share about my setup.
I have a used Pentium II with 256 Mb of RAM (total cost 100 $). I run
Windows 2000 for stability with most services disabled (i'm a computer
professional) to save on performance. The hard disk is partitionned in C:
and D: and the physical disk is on a drawer which mean it can be easily
removed when i'm afraid of being stolen or for reconfiguration purpose.
The hard disk is a 20 Gb and hold all marine card and 5000 MP3 that i carry
aboard. (total cost of disk + drawer 100 $).
The screen is a 12 Volt native Proview 12 inches (total cost 250 $) and
visibility is very good but i'm not in direct sunlight, i'm inside the
boat.. The computer is feeded by a 300 watt inverted and amperage while
running is about 10 A. Truly said it is a lot of Amps, when someone think
that my freezer draws only 4 A when working....
A laptop (i got 2 but not on the boat) would draw only 3 A. The 7 A of
difference between the PC and the laptop is largely overcome by an energy
management strategy (hibernate the PC when not in use and having separate
starting/auxiliaries batteries) and by the fact that it is fairly cheap,
cannot be stolen because the PC is bolted under the floor of the boat, and
could be repaired/replaced anywhere.
Have this configuration for 3 years without any problem and now with WiFi in
most marina the pleasure is just beginning.

From all of this discussion I have learned that I have two choices:
Use a cheap, fixable and adptable Desk top PC with an LCD monitor to
hold power usage down, and an inverter to supply the power, or
use a laptop.
The first choice uses more epower, the second choice loses on
varsatility and fixability.
Yep that's what Ive learned as well
Maybe I can use the LCD monitor also as TV for
watching movies and therfore would get a larger monitor thatn usually
comes with a laptop.
That's another reason I was curious abt using a desktop
on a boat/ sail boat. I was thinking that one could
put a TV card in it and use it as a TV as well as
general use PC
see link for such cards and devices

In the link above there also exists a USB TV card that
I suppose one could use with a laptop as well, correct?
