I have OpenCPN on an Acer 8.5inch Netbook for a backup, it works fine, I dont think they make them anymore, i think they make a 10.5 inch now,I use a small GPS antenna
with it, the antenna
is about 50.00 and plugs into the UBS Port it works inside you do not have to mount it outside, looks like a black hockey puck
,you can either download NOAA charts
or use an external CD burner to load charts
with. as most small computers
do not have a CD.
I have never used it full time, as i have a dedicated Desktop
for full time Navigation
which also uses OpenCpn, which is a fine program.
