Nothing is in the bilge and nothing is unsealed. It is in a NMEA 4X/ IP67 box. You are correct that all kind of things like WiFi, email servers, etc are unreliable. There is a ton of fault tolerant code in there now. Retries, exits to loops so they cannot hang. The ultimate backup is that if I don't get an email in the morning, something is wrong. That is why I send an email every day regardless of the conditions on the boat. Perhaps I should write all that up as well.
