Onboard Alarm Panel

[Mal Reynolds]

I'm designing an alarm panel for when aboard, a place to consolidate separate alarms and wondering if I'm missing some ideas and maybe ways to design some alarms. Here is my alarm list so far:

Man Overboard (triggered via AIS MOB device)
High Water in Bilge (triggered by pump switch)
Propane (Triggered by sensors in galley and bilge)
Water in Fuel (Racor sensor)
Fire Alarm (sensor in engine room)
Stray Current test (for the aluminum hull)
Low voltage

I'd like to add an anchor alarm, not sure how to do this. I don't want to be dependent on my iThing.

Smoke and CO alarms are near sleeping quarters.

What other alarms should I think about? I'm not really interested in wind or course change alarms. Although maybe a rapid barometric pressure drop.

When off the boat I guess all these sensors should also be wired into a monitoring system - Cortex? so I'm notified when off the boat, but I haven't really thought this through. Maybe add refrigeration alarm, motion detector?

Has all this stuff been solved and I'm missing something? Or no one does it because it's too costly & complex?
