Hope I'm not duplicating anything, don't think so. It seems there's a bit of confusion about MMSIs and things like Marinetraffic.com - and this is something I have learned about (the hard way), so here goes.
The MMSI (Maritime Mobile Service Identity) is published on a public database: http://www.itu.int/online/mms/mars/ship_search.sh - the purpose is to enable international recognition of signals including DSC (Digital Selective Calling which allows a distress signal to be sent automatically from a VHF radio) and the signals sent out by an AIS (Automatic Identification System). Anyone can buy an AIS receiver but you need to be a license holder to use a transceiver. Many leisure boats have just a receiver but an AIS transceiver must be fitted aboard ships of 300 gross tons or more which are in international waters, and all passenger ships. There are two "classes" of AIS but we won't get into that.
AIS observer websites (like www.marinetraffic.com/ - there are others) get their information from a network of contributors, many of whom are shipping enthusiasts, who have receivers and who pool their information about vessel positions. There is at least one enthusiast at every port in the developed countries and quite a lot elsewhere. AIS transmissions are by VHF so they are line-of-sight and ships far out in the oceans will not be "seen" except by other ships nearby unless they send their AIS signals via satellite. Sometimes a boat can "disappear" from the observer webites because it has slipped through the net. That happened to us last year between our approach to Newton Ferrers and our arrival at Mylor.
Ship and boat owners can choose to add information to the observer websites. I have put a picture of our boat on marinetraffic (MMSI 235116115). That's optional - on the other hand any member of the website can post a picture of the vessel if they have one.
Capital_R - There's a catch in all this. Your ship's existing navigation suite will have the old MMSI number programmed in to each individual component which needs it, essentially the AIS transceiver and all the VHF radios. Only an authorised dealer can change the MMSI number in a piece of equipment and many items will only accept one change of MMSI - or none. On our boat we still have a VHF radio with the old German registry MMSI programmed in, and that radio is not re-programmable, so part of next winter's refit is to throw that radio away and buy a new one. Our radios are cheap - I suspect yours will not be. Sorry to be the bearer of bad tidings

Brilliant information, thank you very much.
No wonder the darn thing uses so much power... with all the things it does in the background.
I'm not giving up on my goal of a "quiet ship" for anchoring. I actually had a dream the other night... the best dream possibly in the history of all possible universes..... that i fell asleep over the side of the boat... and woke up at dawn to the sound of waves lapping against the hull.
I remember from days in Fiji, when the superyachts started arriving in the mid 1990s, how much of a shame it was that (a) they'd have to anchor so far out (havent solved that); but (b) how their anchor genset could be heard echoing all over the bay before breakfast... and how their owners must never have really got to appreciate the beauty of an anchorage where you wake up hearing little waves lapping on a soft white sandy beach to the sound of birds, and the odd thud of a falling coconut and the grunt of a wild pig somewhere in the vegetation (without painting too specific an image)....!
So... silent ship is the goal...!

The wooden boat had about 1000 ah of battery storage. That was enough to run 240v fans all night (not ac) in the south Pacific with a genset for 1hr for breakfast and 90 minutes for dinner.
This steel boat has a huge amount of generator capacity... so charging shouldn't be hard....
As for the solar? https://www.smartflowerpacific.com

As for me currently? Massive war parade today...

Looks ok solves the aesthetic issue -if it - or multiples are powerfull enough .
But when its windy ,hmm
Flower pettals are delicate
Reminds me of something Pine wood studios would knock up for a Bond Villian
BTW the "wooden " boat would had had 24v lights ,bog pumps and other stuff.Fridges for eg .

Absolutely.
Will rewire with appropriate LED setups.
Problem: those solar panels dont actually track the sun.... they have pre-programmed arcs to follow... bases in lat, long, date, and time....
So crud at anchor.
When moving... don't mind running alternator or genset if main is already destroying the silence...

I always liked his story of living on a yacht in Monaco... bur these days, apart from the extreme distance from the rest if the world - New Zealand and the Pacific was the modified plan that I had in mind....!
View this morning...

Whilst I understand the appeal of going green and trying to harness the sun this could be one of the few occasions when "our" technology can be used to solve a problem on large ships.
A 50 feet I am never far from engines and generator. We have an Onan (Cummings) set up on the boat with underwater exhausts and it is genuinely silent to the point where I've left it running by mistake. You could easily use a couple of those to keep things running in "silent mode" and enjoy your water lapping experience. They make them up to 99kW
Just to put it into perspective this is us in a silent location where all I want to hear are the birds singing:
My suspicion is that there will be so many systems running in the background a battery solution will be impractical. Just the air handlers to keep air moving around the sealed ship, lighting, safety electronics and so on.
When planning resource use it's easy to ration yourself but as soon as you have guests on board it goes out of the window. Water and power get wasted. So don't fight it, make provision for it.
In the general scheme of things I suspect this will be one of your easier problems to solve.

Thanks Henry,
Wise advice. It might end up being one of those things that isn't totally practical, but just desirable. I was talking so some of the Tesla guys about putting in some poeer packs (i was building electric cars 10 years ago before banking took over) -
The wooden boat has an Onan in it. Very comfortable with that.
I'm still presuming that the boat will have me on it 90 days a year, 100 if I'm lucky... guests for maybe 30 (may or may not overlap) and be parked for the remaining 250 days or so....
Plus. I think she's got enough power to light up a small town if needed. On the initial inspections last year, they showed me the automated load balancing and 'switch ins' (?) where the system would start and shut down various gensets depending on load.
How they would sync etc wasnt committed ro long term memory... but Im certainly not averse to putting a mini genset in there too.
I'm even toying with a wind turbine farm up by the radars and sat domes....
I just have this very strong attraction to feeling disconnected - perhaps it's the childhood of growing up on a hill country station and the very remote pacific...
Or the reliability of magnets and photovoltaics....
But i think we'll end up with both. Im sure someone's even invented a buoyancy generator too... which we can deploy from the A-frames at great aesthetic compromise!!!!

I'm having withdrawal symptoms, due to no new posts on this thread for 2 days. I might stop losing interest in the mobo forum if I don't hear any more soon.
I want to know if the endurance trials on the tender have been conclusive. I want to know if the custard has arrived. I want to know how long before the lights go out if you turn off all the generators.
This is all crucial stuff, you know.

More to the point, I want to know when the forum meet in Gosport's Wetherspoons is!
