I'd want to fit in a trip to Rotterdam and then down the Rhein for a ways...maybe to
Basel.
Yup Europe by boat does sound like a very interesting trip. Sort of a
Viking cruise where you get to decide where you go and how long you
stay.
It does beg the question, how would the electrical shore tie work at
220v 50HZ.
You might need to buy a big assed transformer. I imagine most of the
motors would tolerate the 50 hz but you need to read the nameplate
rating.
That "transformer" might need to be a VFD. (lighter but more
expensive)
Might be smaller to do as we did at one company to generate the 220-50.
Had a motor driving an alternator. Was not real big and we were driving
300Mb CDC disk drives.
