Also, if I recall correctly, you need to use special romex in places where the Sun does shine. UV resistant sheath is dark grey, yes?
I presume that GFCI protection is needed for this as well. And I would expect that the GFCI be installed up on dry land to protect someone that might grab the feed wire while in the water. Well someone might :-(

i will throw my 2 cent worth there also but the wire staples are rusted bad but one question how the devices can stand the evoerment and i belive that is salt water which it bring me memories about that. unforeturely the sec 555 deal with marine and the devices like boxes and etc should stand the salt water also that part it puzzle me for while but mandatory gfci is need no matter what size device will put out i did see 3 phase version use gfci also unforetaly i did not get the manufacture name for it. and the cable what i see it dont have proper support in case of splashing water and in winter time dealt with ice ( that add weight also)
Pas de problme,il marche n'est-ce pas?"(No problem, it works doesn't it?)

555.19 only requires gfci protection for 15 or 20 amp 125-volt receptacles.The 30 to 100 amp receptacles supplying shore power do not require GFCI protection.
I have never seen anything called boat cable.Every dock that I have seen,wired,or had to troubleshoot was wired with either RNC or RMC.The only cable was from the boat to the outlet.(on floating docks,LFNC was used at each end of the bridge(gangplank?)to allow for varying water levels.

Hi, I am an experienced amateur...but this is not intended as a 'how do I do it myself' question
"Boat Cable" is similar to NM cable, but its intended application is for the electrical wiring on a boat. The big difference in the conductors themselves is that _stranded_ copper wire is used, nominally to provide better reliability in a high vibration environment, and the conductors are tinned, to provide better corrosion resistance.
The cable is certainly made to _different_ standards than NM or UF; for example the single conductor marine grade 14ga wire that I have at my desk is printed 105C DRY 75C WET OIL RESISTANT...TEW 105C or AWM... suggesting a higher temperature rating in harsher conditions than the THHN found in NM. The cable is also probably more flexible and less prone to mechanical damage in cold weather. The outer cover of the boat cable in the picture above is quite likely UV resistant, but I doubt that the cable is rated for direct burial the way UF would be.
One _significant_ difference is the stranding of the conductors and the tinning of the conductors. I bet that the various terminations in wire nuts or on the back of the receptacles have rather different performance and reliability characteristics with this finely stranded wire than with the relatively stiff strands found in regular THHN or THWN or the solid wire that would be found in 12ga or 10ga UF.
