Dick, and the list,
I guess I failed to make my point clear: There appears to be a whole
lot less of "stuff" that requires electricity on a 65' "luxury" yacht
here than on an equivalent size American yacht.
An 35' express cruiser that I once owned required 120 VAC and 60 amps
to run everything on it. The next size up (40') required a 240 VAC / 50
amp connection to run everything.

There is a good reason for that thin cord. A boat
that is using all those loads will require some amount
of total power (watts). watts = volts x amps.
So if that boat is in the US, using 120v, it will draw
some amount of amps.
But if it is in Ankara, using 240v, it will draw only
half that amount of amps.
Half the amount of amps requires only half the size of
wire.
That in fact is why 240v is used around much of the
world instead of 120v -- less copper is required in
electric lines, and copper is expensive, so higher
voltage saves a lot of copper cost -- albeit at a
higher risk of injury from electric shocks.
