And the most obvious way to move a ship is by sea. Ships are made to move on water. There is no more logical way to move a ship and its content across the Mediterranean Sea than by sailing it.

Despite existing land-routes shipping remains the backbone of global transportation and you would be shocked to find the amount of ships transporting goods and people across the Mediterranean Sea, or the Baltic Sea, or any other route that has land-routes available. But it goes even further! Rivers and channels remain crucial shipping lanes inside Europe despite streets and train-tracks being right next to them. Almost as if ships are great means of transportation!

EDIT: I am sorry, i got cocky with that comment.

Despite existing land-routes shipping remains the backbone of global transportation and ships usually are preferential to land-routes in particular in the Mediterranean Sea or the Baltic Sea. There also are many shipping routes based on rivers and channels, which have streets and train-tracks right next to it, but maintain shipping as the preferred method of transport for many goods. Shipping is a great mean of transportation and in many cases it is the best option.
