MOB functions

[dhs.short@gmail.com]

Kramp Electronics, Seal Cove, ME just installed an eS97 on my 1997 Sabre 362 sloop. I also have a Standard Horizon GX2200 VHF for AIS reception and a SmartPilot SPX-10.

Because I often sail alone, I am considering installation of a device (WamBlee info below) which detects DSC & AIS MOB alarms from personal AIS/DSC beacons. It can then shut down the engine. I also hope it can disable the SmartPilot which, if sailing, would cause the boat to head up into the wind.

A couple questions:
1. Can I achieve some, or all, of the same results through the eS97?
2. If installing the WamBlee, what would be the best way to disable the SmartPilot?
3. I see the eS97 can sound an alarm.

I see that Raymarine has a very sophisticated and expensive looking digital switching system requiring special networking equipment etc. I am wondering if the above can be done without getting into all that. The WamBlee unit is $300.

Info on the WamBlee is located here: http://www.wamblee.it/marittimo/w440/?lang=en
1. It shuts down the engine through either a normally open or normally closed switching circuit. These two circuits have a common leg.
The ignition wire could run through the normally closed circuit, verified by Westerbeke distributor.
If the best way to disable the SmartPilot is by cutting power, then both the SmartPilot & engine might need to be cut by a relays so power is not backfed through the common leg.
2. Would the following, per the manual, be useful in achieving the results I am looking for?
“The W440 is able to generate a NMEA 0183 sentence (4800 baud) repeated every two seconds. This ruling is as follows: $PWBEE,MOB_SWITCH,ON*<crc> where: ON = as close contact
Further clarification on the use of this NMEA sentence can be requested directly to our technical department.”

Thanks very much
