Solo trip so lots of time to think about things, OP and the Pi 3 were very well behaved, the vnc server crashed a couple of times but I don't think the system as a whole needed a reboot once.
So I was wondering what you have in mind for the future, if you've even given it much thought, the progress has been incredible in such a short time! With Opencpn a major plus is the large selection of 3rd party plugins, many really useful and possibly not something a single piece of bought software could hope to offer. OP is obviously a different beast to opencpn but is that an option you've considered? Make it easier for users to integrate bash scripts, python progs etc in actions or deeper down?
Also, I now have a Sony Xperia tablet in the cockpit, a Raspberry pi 3 down below and a few cheap sensors off eBay. Which results in a system which would have cost thousands if even possible just a few years ago. I can see the temperature of the exhaust, alternator, with so much more to come. I really think OP and android made for each other
So that's it, but finally, as a sailor in the middle of a black stormy night I want a system with a tablet in the cockpit which is reliable and won't have me worrying that it might crash, I want an on screen chartplotter with ais and I want early warning when things start to change, like the engine getting too hot. And I want it to cost next to nothing and draw hardly any power!
Nearly there then!

Hi
how is the experia table behaving in bright sunlight ? can you still read the display ?
If you want an alarm for low battery try a resitor bridge and an AD converter. I would not risk a direct coupling of the pi (and using the built in AD converter) to this bridge, but you should be able to use an arduino nano and an optocoupler connection to the raspberry Pi
