I am very satisfied with the small VIA pc I bought five years ago. 833 mHz, 512 mB ram, fanless (processor is mounted on a large aluminum
chassis and gets not more than lukewarm), 40 gB HDU (today I would choose a solid state HD even if the present HD runs ok) and it draws 1A at 12V. I put it in a safe place on some rubber mounts. The screen
is a Philips 170S, 17", which draws 3 amps. I switch it off when possible. If you want I can send you more info but I guess after five years there will be more modern pc's nowadays. Take a look here:
Computers for Sailors
-Most of all I love the fact there is no laptop
that can fall down or get splashed with coffee. Just a keyboard and a mouse (and yes, I indeed have a few backups for those...)
-The absence of a fan means: no build up of salt
, no noise
-There are two real physical RS232
comports (one for GPS
and one for AIS)
-There is the Video-out feature. When I want, I switch on the FLS (Forward Looking Sonar) in the cockpit
. The Video-out on the Via PC is connected to the Video-in on the FLS, so I can watch the NAV-program on the (bit small but ok) FLS daylight screen
in the cockpit
without additional cost.
It's no power-giant, because there is anly so much you can do without forced cooling
. For nav programs it's more than strong enough.

I guess this is important for all sailboat owners who are not velcro-ed to the pier...
>Or what average energy consumption (Ampere) may a system (we >presume a separate display/ monitor which could be switched on and off) >have which runs permanently while cruising?
The VIA pc runs constantly during sailing but 90% of the time with the screen switched off. I estimate the power draw on average 30 Ah per 24 hours.
In the anchorages
we use the netbook/laptop and they use way more.
How many Ah do your batteries (or do you have only one?) have?
House bank 660 Ah (used to be 1200 but that proved to be unnecessary)
>Do you have any kind of solar
panel and/ or wind generator
1 IBC 1x120W
3 Sunware 3x50W
1 Kiss windgenerator.
Your post suggests to me that you are in the planning stage of your electrical system
. If so, take a look at Nigel Calder's book about mechanical and electrical
systems on a boat.
