Scott, there is a use for a device which alerts people on a vessel that someone has fallen overboard. Generally it is quite different from a rib though. People who sail in watches may well be interested as often only one person is awake and on deck at a time and so if someone goes over the boat can be far away. However consider that those devices should ideally do the following:
- Alert other crew members to the incident audible/visual
- mark the casualty position on the chart plotter
- possibly reduce speed / remove autopilot, if that isn't going to expose the remaining occupants to more risk.
-If single handed possibly activate a distress message (that is probably the hardest bit to achieve)
Preferably the system would be activated automatically (by loss of signal so it fails safe) as you can't assume the casualty is conscious, or capable of pressing a distress button. If you believe this is not true Google cold shock.
There are a few commercial systems around for this sort of thing. Whilst you can build the parts cheaper, you can't robustly test them etc...
