It depends on your crew complement or lack thereof and where you are sailing..
If you have a complement of crew (at least one other adult) on board
Then the MOB (DSC/AIS SART) is your first, best option. No one is closer to rescuing you than your own vessel and the MOB1 and similar DSC/AIS SARTs call YOUR boat and alert your crew to you condition.
Once you have a MOB on each persons life jacket, then you can and should add an EPIRB
to your boat, or possibly a PLB at minimum just in case you need to request help from authorities a long way off.
If you are a solo-sailor and might need rescuing after falling off your boat (or in any other situation) you really need a PLB (not a MOB)
If you are in inland waters (SF Bay, Puget Sound
, Cheasapeake, or something similar) with nearby boats and Coast Guard in VHF
range, then a VHF/DSC/AIS MOB might work
okay, but you have to manually activate the "all ships distress" call after it automatically activates because by default it only sends the distress
call to your own boat first.
If you are offshore
, a MOB really won't do anything for you.. It will transmit a distress
to your boat but no one is on board to hear it, and you can switch it to all-ships call but the range will be limited to a couple miles.
A PLB on the otherhand sends the distress to the authorities via satellite
with your position and they can call other ships, boats, planes, etc in the vicinity to help you.
We have a family
on board (4 of us) and we have 4 x MOBs (1 per person) and 3 PLBs (2 for night crew and 1 inside the liferaft), plus a category 1 (auto deploying) EPIRB on the boat.
In any case, the PLB and MOB's solve slightly different problems..
MOB for one crew overboard
from a vessel with additional crew.
PLB for all is lost
, come get me, no one knows I am here problems.
Just my $0.02.

I would be interested in the experience and thoughts of members as to what they consider to the most appropriate.
