Hope the damage isnβt to bad. Lovely bikes, make it better. Some wankers around huh!

Ok I know enough to know that is like asking how long is a piece of string, however just trying to get a feeling of whether my batteries are performing ok or not - I was expecting better...
Voltages taken from MPPT controller readout.
After cruising or running engine each day for a minimum of 4hrs, after an hour or so the battery is showing 12.6/12.7 volts (seems ok), by morning this has dropped to somewhere between 11.7 to 12.0 volts (not as good as I had expected).
Electric usage is 12v fridge, a couple of lights, 3 to 4 hrs laptop charging (although one night no charging to see what difference it made to the batteries - none), Bubble stove diesel pump and water circulation pump, water pump, inverter (turned off overnight).
Battery bank 4 x 110 amps.
Initially just looking for info as whether this seems ok or is something wrong.
That's almost exactly my experience with Desiree, I have a smaller battery bank (2 x 115 Ah), fully charged (and almost brand-new) batteries will be around 11.7v in the morning. The fridge is the big user but I can't do without it so I am just resigned to replacing the batteries every 18 months.

The fridge is the big user but I can't do without it so I am just resigned to replacing the batteries every 18 months. A compressor fridge uses about 35AH in a 24hr period. But some of that time presumably you are running the engine to charge the batteries and/or getting some solar input. Even if not, 35AH should take 230AH of batteries down to 195AH ie if starting with fully charged batteries and with no other load, you should be at around 85% SoC after 24 hrs.
11.7v represents about 20% SoC aka really flat. So something is not adding up. Either you have a lot of other loads on, your batteries aren't properly charged at the start, or most likely the actual capacity of your batteries is way below 230AH.
Sorry but as Scottie said, you canna change the laws of physics. Blaming it on the fridge is a falsehood. Presumably you have no proper monitoring of discharge AH?
We have 450AH - a little less than twice as much as you - but the fridge doesn't take a noticeable amount. If everything else is turned off the SoC drops just a few % overnight.

Well, there's also the inverter, that gets quite warm. And then the cabin lights, and the water pump runs from time to time. I know when the batteries are goosed though, because the fridge won't fire up and all the fish fingers in the freezer compartment thaw out so the whole boat starts to stink of fish. It's a kind of olfactory battery wear indicator. So then I go and buy new batteries and I bully and browbeat the people behind the counter at the motor factors into selling them to me at cost price. Which they eventually do, in order to make me go away. This happens around every 18 months or so, which I think is probably reasonable for a liveaboard. Batteries are ephemeral by nature.

On my first boat I had a lovely little Sony black and white telly. When the batteries got low the picture got thinner.

Well...my Aprilia Factory was stolen last night from the marina, stored under a bike sheet...fortunately found this afternoon 100 yards away behind the church with ignition lock wires cut/ shorted...pushed away and parked under lights to 'work on' ! ππ Immobiliser prevented any chance of it starting but thieving bastards are around everywhere!!! Hassle for me now to get it all fixed and working again. thieving, ignorant, lazy twats...I hate them!π‘ Absolute scumbags! Was it chained up or anything? I'm a bit paranoid about mine, chain it up right outside my bedroom on the basis that if someone tries to nick it I'll hear them. Nobody has tried so far.

Myself I would be ready to kill the basterd(s) that were trying to steal my bike (haven't got one anymore nowadays). I'm sorry for you that you'll have to sort the damage out, but it could easily have been MUCH worse, as they often use a van to put the stolen bike in and drive off. You should almost have a little lapdog style Rottweiler, Doberman or vicious Pitbull to sleep right next to your bike and attached to it, to make sure that it won't happen again, and it will maybe let you see the left overs of the potential culprits in the morning.

Picture of the back of the alternator could be good. Maybe a simple regulator swap to get 14.4 or more. Picks of alternator
Bottom one
Cover removed, whitish box says 'Replacement for 1861546 12v'
Will be getting some new batteries as even with just 1 led light and central heating pump being used between 16:00 and 08:00 last night battery voltage dropped from 12.5 to 11.9. Everything else was turned off including the inverter.

1861546 is a CAV regulator, easy to change, now just got to find one with a higher voltage.

Thanks both. I'll replace the batteries first, if charging voltage still too low then the regulator, if no luck after that I'll ask further questions.

Heres a 14.5v regulator but I suspect it could be the same as you have www.woodauto.com/product/VRG3615Prestolite used the AC5rs as the base for one of their altenators it may be worth contacting them (Leece-neville/prestolite) to see if the have a 14.7v regulator.

Took me ages double checking and Gazza came up with the answer before me......
