I have a feature request to improve MOB
We do only shorthanded cruises and the dangers of MOB
while the off-watch partner is sleeping somewhat bothers me. Imagine a situation like the one pete Hill faced
I think something like a Raymarine
Lifetag would at least help in these situations as even if it still goes unnoticed for some time one could see where the MOB happened.
My idea is the following:
Many / most current computers
have bluetooth capabilities. Why not connect the PC to a BT device and check periodically if the connection is alive. If its dead for longer than xy seconds we assume a MOB situation, place a marker and sound an alarm
. Maybe also change the AP heading into the wind
or run in circles around the MOB position if under engine
but this needs to be configurable as this could be dangerous for the boat
and the crew.
The device could be any device, like a smartphone or maybe just a cheap
BT headset (these start around 5 USD on ebay so I don't care if they are not waterproof).
I know one has to live with sporadic false alarms due to lost
connections, dead headset batteries, interference
, etc. Of course this can only work for smaller fibreglass or wooden boats as BT range is limited. But I guess this is a good portion of the OpenCPN
installations out there. I tried it on our Mahe 36 catamaran
and there is full BT coverage everywhere with the PC installed at the nav station.
what do you think?
