Well , not really.
Lets see... cost of a dedicated pc on board.... varies of course, but one can be built for 300-500.
OS 99 for linux
to 250 for windows
Monitors, Well there the price can be all over the place, but 19" at the nav station 250, plus swing arm mount, then the cockpit
sunlight viewable, water
resistant touch screen, is 1500.
Then software... go cheap
with a free open source program, or expensive with nobletec admiral max pro.... 1500 plus charts
So you have a total of between 2150 to 4000 plus. And thats for 2 screens, plus the ability to change os, software, charts, ect. Things change fast in the new electronic world, a chartplotter does not. A pc is upgradeable.
Last I checked at good chart plotter was 2100 for a 10" garmin
plus charts, or over 4000 for a furuno
, but will only work in one place... and won't give you the flexability of a dedicated system with mp3, video, internet
So really the cost of a pc based system is lower, unless you insist on something like a panasonic toughbook, which I would not. Much cheaper to build your own, or have someone build it for you like stealth computer.
But I guess if I had money
to burn, the dual dedicated chartplotter upgraded every 5 years would be the way to go.....
