Is it noble to have a small tow boat guide you through the curves? It is if your yacht is as big as a house.
Look closely and you can see the gun turrets and crew wearing flack jackets on Sea Bowld (not really).
In case you were wondering... the crane that pounded the girders into the sea floor comes back and grabs them with this green contraption and yanks them out. That's one heck of a grip.
