Sailing ships must have rudders. Columbus's ships were no exception. There is a nice picture of a nao at the link. The Santa Maria, The flagship for his voyage when he discovered the new world, was this type ship. The Niña and Pinta were caravels. They also had rudders.
Airships have engines pushing them through the air and big rudders at the rear. When the rudders are put at an angle WRT the airstream, the ship will turn. For up/down they can either vent/fill some of the lifting gas, or - to some degree - use rudders for that too.
in white water no in racing yes

There are no rudders on the Belle of Louisville. It is powered by a paddle wheel, which is made up of many bucket planks that turn the paddle in a circular motion, which in turn propels the Belle of Louisville.
A sailor can manage a ship better with rudders and move the ship. Larger sails were also moveable so they could change direction and speed.
