You can't travel directly from Amsterdam to London by ferry because London doesn't have a ferry port. You would have to travel from Amsterdam to Hook of Holland by train (or drive), catch a ferry to Harwich and then take a train (or drive) to London.

There is no ferry to Moscow from London. Both cities are inland, and Moscow is a very long way from the sea. You would normally fly from London to Moscow. You could get a ferry from England to France or the Netherlands, which is a crossing of just few hours, but then you have a very long drive to Moscow, over 2700 kilometres or nearly 1700 miles. So you could be travelling for days.
You can't take a ferry from London to Caen. The nearest UK port for Caen (Ouisterham) is Portsmouth in Hampshire.

There are no ferries from London to Rome. Both cities are inland and even the journeys between their nearest ports are too to make a ferry viable. So people fly between the cities, or they could go overland by a variety of routes and take a ferry from England to mainland Europe and drive to Rome, though that would take several days. So flying is the best option.
