Moggie, OpenCPN will not run on an iOS (read that to be Apple handheld device such as iPad, iPhone
etc) device. You need something like iNavX
, iSailor or similar for the iPad. These range from $8-50ish USD. This is if you wish to ditch the laptop completely.
If you want to keep the laptop which WILL run OpenCPN then you need a different app from the app store. There are several which will allow you to control the laptop and see the screen
. Are you using a charging
cord for the laptop that would plug
into a cigarette lighter in a car? (12v) if not that would help but not solve this problem.
The suggestion of changing the laptop to a netbook is a good one. If you don't want that expense then I'd ditch the laptop completely and just run iNavx.
What are you trying to use in OpenCpn? Are you using radar
or just plotting?
Hopefully this was will make sense. If not you are welcome to PM me. I'm not a guru on either item but I understand each well enough to get by.
