Here's someone who knows enough about electronics to design using Eagle and write firmware yet feels it's an acceptable risk to have a custom exposed board in their bilge. From a systems level critically relying on any of the following seems iffy in a marine environment where safety is key: wireless (unreliable; may be accidentally suddenly degraded by changes to outside environment), remote store and forward email notifications (unreliable and slow), single MCUs (due to SPOF), unsealed electronics in the bilge (extremely dangerous and often causes corrosion and loss of rudders), press-fit electronics (bad in marine environments, particularly near engines, due to vibration).
