Just plus into the Pi and works.
I used opencpn on a computer for my Bahama trip. Used seaclear before that but really like opencpn. Used the NV Chart plug-in for the NV Bahama charts. Still had to buy those of course. I think $150 for the digital charts and full size paper charts.
Had the computer tied to an older Garmin handheld GPS ($40) with a serial cable. I would put in the way points for the Day's Journey with opencpn and send it to the handheld out in the cockpit in a couple mouse clicks. On the Mac the monitor is mounted in the companionway entrance so I could see it from the cockpit
We are now using the pi as a backup to a to a Standard Horizon chartplotter. Have the pie running all the time just at the nav station inside. I use OpenCPN for all my route planning and will finish connecting it to the SH chartplotter at the helm in a few days. I will then be able to send the next days waypoints to it via a serial connection between the nav station and the helm.
If you haven't yet download OpenCPN and the NOAA charts, both free, and give them a try. A great program,
Sumner
