The cruise ship Statendam is seen approaching Oranjestaad, Aruba. You’ll see a tugboat standing by, then disappear behind the leaward side of the ship. Take a look.
The wind almost always comes from the east in Aruba. Thus the tugboat has moved to the opposite side of the ship. Plus, it will need to be on that side to help the ship to the dock. Most modern cruise ships have an array of bow thrusters, steerable pods, and other devices that enable them to dock with very little help from the tugs. Still, it makes sense to have one handy in case of a failure of man or machine.
Bon dia from Aruba.
