Mark T has the correct answer.
Very heavily insulated due to the envirenment it goes thru. Remember its left out in the open.
If you were to cut it open you will find its the same as house wiring but in marine applications the coast gaurd specs call for twisted/stranded wire instead of solid like in house wiring

Answer #3 is correct. IF, you talking a 12 volt system. If it the 120 volt AC shore line, it may be it use stranded wire (More flexible) and not one solid as a house use, again, it would require a larger gauge.

Through a cord of the same thickness you have following energy transfer:
30Amp at 12volt allows you to drag 360 Watts
30Amp at 24volt allows you to drag 720 Watts
200Amp at 110volt (USA?) you drag 22.000 Watts
200Amp at 220volt (Europe) you drag 44.000 Watts
So to have more energy current on low voltage you need much bigger lead to arrive at the same Watts:Energy/Power..

as voltage increases wire guage decreases. in a six volt car systems the Battery cables are almost twice as thick as a 12v car system. this is also what is causing car manufactures to switch car to 36 of 42 volt to save weight on wires.

Because it is encased in rubber for the wear and tear it takes on the boat and around the docks.
