Which MOB/S&R/Distress Beakon should I choose?
There is now a confusing array of Personal Beacons, each with their own advantages.
AIS-SART’s enable any AIS equipped vessel to find a MOB victim.
MOB alarms alert the crew when a member goes too far from the master unit.
DSC Portable radios enable the coastguard to fix the position of the victim if he is in range.
EPIRBs transmit the position via satellite (when they pass) to the authorities.
A vessel well crewed in the mid Atlantic could use an AIS-SART, maybe backed up with a proximity MOB alarm if there was likely to only be one person on watch.
A single handed yachtsman might be better of with an EPIRB, and both should ideally carry an EPIRB in the liferaft.
In coastal waters, particularly if well crewed an AIS SART will not only enable the victim’s own boat find him but also any other AIS equipped boat nearby will be able to assist too.
So the final decision should be based on :-
· The area sailed in.
· The number and strength of crew.
· The minimum number of watchkeepers.
AIS based maritime emergency channel
Saving lives is simple now with AIS - easyRESCUE
The Easy Rescue is a personal AIS transmitting beacon. With a built in GPS it transmits an emergency AIS-SART sentence (MOB) which triggers an alarm on all AIS enabled chart plotters / PC’s within range, along with the Lat/Long of the victim. The GPS is a new generation fast acquiring type and the VHF AIS transmitter repeats the message and position several times per minute. This enables all vessels within range to assist with the rescue if they have an AIS receiver or transponder. Now, the chances of survival are greatly increased.
The Weatherdock Inc. located in Nuremberg, has taken up a major problem in shipping: the effective and simple rescue of a man over board (MOB) person. So far, it is very difficult to determine the exact position of the victim, to launch a successful rescue. Today's life-saving equipment will range from "lookout" on lifebuoys to so-called electronic beacons (EPIRB). In all these systems, the current position of the MOB person is no longer covered by "his mother ship". That makes a quick rescue difficult or even impossible.
The previously mentioned disadvantages are eliminated with a new system developed by Weatherdock.
The easyRESCUE sends the position data of the castaways on a standard FM radio frequencies with standardized data: the AIS data. AIS is an internationally valid standard, which transmits the current position of the transmitter, speed and other data. Novel about this rescue-system is that using a commercially available navigation device (plotter) or a PC and the associated AIS receiver location data from the easyRESCUE can be received and even will be displayed as a marker on the chart.
Compared to today's solutions are several advantages: First, all vessels with AIS receivers can be involved in the rescue operation. Furthermore the rescue can be started without waiting for intervention by the Coast Guard. Hence the easy-RESCUE is a huge potential for growth when it comes to the successful rescue of MOB persons.

What else do I need?
Apart from an AIS receiver or transceiver connected to a chart plotter / PC, nothing. The Easy Rescue maybe attached to a life jacket or kept on a lanyard. To operate just slide the safety cover off (releasing the coiled antenna) and press ON. A test button allows regular test of GPS function, battery state etc.
