I want to add a cigarette socket which is permanent live. Obviously a fuse in line but what size and do I need some anti-surge gadget or anything?

Locate the socket next to the fuse board, then take power from one of the fuses, no need for anti surge. That's what was fitted to our boat when we bought it.

IIRC the max load for a socket is 15amps, so just fit an inline fuse of that rating near to the socket, unless you happen to haves spare 15 amp circuit available on your panel.

Fuses and cables should be sized to match each other and the maximum load or maximum amps the socket can take (not more than the socket is sized for)

If you fit a 15 amp fuse in the supply to the socket anything you plug in with lighter rated cable should also have a fuse to protect that cable as close as possible to the plug, preferably incorporated into it.
The ordinary cigarette lighter sockets are pretty poor as there is no positive retention of the plug. Poor connections and even over heating if large currents are drawn are possible consequences.
it would be advisable to find plugs and sockets that lock positively together.

Normally I hate it if I ask where to buy oranges, and get told about the lemon wholesaler, but ...
Out of interest, what do you want to power? There may be a better solution.

Only low power load stuff like phone charger,laptop,camera etc. Only one at a time.

For those sort of things, surely it doesn't need to be permanently live?
My car lighter socket is fused at 5A, I have fitted about four round the boat which come off existing 5A circuit's and one that is switched and fused at 10A. They all go through the battery isolation switch.

Motion activated cameras don't work without permanent live.

No real reason but they lose their memory if they go flat.

To me, 'permanently live' suggests straight off the battery, before any isolation switch.
This camera won't be plugged in all the time, as you also want to charge other things.
When you are on the boat, I take it that you don't turn off your domestic battery, so unless you put a dedicated switch in the 12v socket, as I have in one of mine, the socket will be live when you plug something into it.
I take it you don't want it live when you leave the boat?
