My yacht has a 240v ring wired with standard solid core domestic cable, the original survey picked this up and suggested that the able be replaced with tinned multi core. The sockets are standard white domestic surface mount units. Is this what most people fit, I can find no marine equivilant?
 
Multi-stranded... flex .. in other words because the single stranded stuff can work harden and fail due to vibration ... they say!

Some people would opt for the Arctic cable that is often used for shorepower leads but it should not be necessary.

If you have surface mounted sockets the weather proofed ones might suit . You might consider them for any exposed positions at any rate

But Id have thought you'd have flush mounted sockets with rear boxes rather than surface mounted ones.??

Solid core conductors can and do fail under flex and vibration stress, though I replace it infrequently due to failure it is not the widespread issue it is percieved to be. There are no real marine grade 13a sockets, properly installed good quality domestic ones are the norm for interior use. Remember that if replacing solid core with multi strand you will need to crimp bootlace ferrules to the stripped conductors to comply with ISO, but sensible practise anywhere that you have direct screw pressure which can damage the strands regardless of the regs. So called Arctic cable, which is usually only rated down to +5 degrees if you buy the BS 6500 stuff from Screwfix et al is perfectly good enough for internal cabling but not tinned. The tinned marine quality 2.5mm2 stuff is available but usually I have to use US colours as European colours are difficult (though not impossible) to obtain in tinned. Should you wish to go down that route then the use of US colours on low voltage AC installs is permitted under ISO & BS standards.
 
The choice of any accessory:

(Double or single socket for instance) can also be guided by IP rating. You can locate the accessory where you like as long as you assess the IP rating required. Or, do what most of us do, find a dry unobtrusive location where regular domestic fittings will be OK.

There are plenty of outdoor type sockets to chose from, many with lids and sealed cable entry, that would protect from rain or spray coming down your companion way, for instance. These are usually marked with IP Rating codes and Google will bring up tables to see what the codes mean.

Appreciate the feeds and links here, I had not seen the Berker units before, the single socket with a hinged cover looks nice and neat for each cabin.

More importantly, I had not realised that you could already get 13amp sockets with USB ports. I am forever hunting around the house to see which family member has stolen my iPad charger! Trip to Screwfix on Saturday.

Those usb ports are unlikely to be powerfull enough to charge an ipad
 
Aldi and Lidl often have these usb sockets and they are cheaper!
