Thank you to everyone who answered this and for the wiring diagram.. 

I cannot believe how stupid I have been!  For some reason for which I
can't account, I was convinced that the "AR" circuit breaker in the aft
heads was for the air-conditioning system, which we never use.  It turns
out that it is indeed the circuit breaker for the aft cabin electrics as
several of you have said. 

Needless to say, once it was made, all the lights work again! 

I'm sorry that I have wasted your time. 

Kind regards and thanks

Am I correct that there is a breaker in the aft head?

 

Richard,

If you sail in any areas north of South Carolina, you must be aware that there is an awful lot of fishing activities, long line, draggers, fish/lobster pot fisherman. These vessels range in size from 32 on up, many in the 50-65 foot range. Commercial fisherman ARE NOT required to transmit an AIS signal unless they exceed 65'.

Many draggers and pot fisherman will be engaged in activities that, to a person unfamiliar with their work and how the boats may vary their speeds, stop, turn around, and make movements that seem arbitrary, all without transmitting an AIS signal.

I personally encountered a dragger fleet off the NC coast one night, no fun figuring out what they were, and what they were up to. Often they're too busy to repond to a call, or often, don't give a crap to get back to you. They do have right of way (vessel restricted in ability to maneuver), and they will take advantage of that .

If you would prefer to keep radar off your boat, good luck. 

I might add, dense fog banks will appear out of nowhere, in many areas north of 35N. Many folks don't tune their radar until it's too late. Without having it tuned, you will may feel a sense of FALSE security until it's too late. 

There is, I firmly believe, a law of the ocean, 2 boats on the ocean will find each other. Spend enough time on the ocean, and you'll become a believer of this law.

Best advise, believe it, and take steps to help yourself avoid it's ramifications.

Best,

Hi Craig, I’ve kept my boat simple. No radar at all. My only chartplotter is Navionics on my iPad. Navionics cannot display the AIS... Instead the AIS displays on Vespers own app. So it isn’t very integrated. (No radar because I do a lot of single-handed passages, and I see radar as a distraction - I’d rather spend my limited resources on other watch keeping activities. I’d rather have AIS than radar.)
