Re: Garmin and Polar View ???
If you have a leftover XP laptop that you want to repurpose, that's fine. Get a sturdy RAM mount for it.
If you're buying new, I'd suggest a Win8 tablet. Much lighter, better form factor, and tapping icons on a touchscreen is much nicer than moving a mouse cursor with a trackpad. Some of them have internal GPS, so you might not need to run Spanner. There's a whole lot of discussion of this over on the OpenCPN forum - and a few threads that I've posted here. Let me know if you want links. It's too late for me to dig them up now.
By the way, OpenCPN can run my Autohelm in track mode. In my case it's done wirelessly via Bluetooth. There's a really geeky thread here telling how I did the hardware setup. I plot the route in OpenCPN, and the Win8 tablet sends the waypoint information to the autopilot. It can do a whole multi-point route, but more frequently I will just tap a location on the chart, select "navigate to here," and the autopilot will do a straight line route to the waypoint. In lumpy seas, the boat's heading seems to stay more stable in this mode than trying to maintain a constant heading, where the sea oscillations can cause the heading oscillations to get larger over time (despite adjusting the gain). The explanation is complicated, and gets into PID control theory.
