Plane or Boat?
As the name implies, a seaplane is a powered fixed-wing aircraft capable of taking off and landing on water. Seaplanes are also known as flying boats, although that name is typically reserved to describe the larger aircraft that can carry more people and cargo.
Seaplanes that can also take off and land on airfields are called amphibious aircraft, or amphibians. Some modern seaplanes, called hydroplanes, can use the hydrodynamic lift to skim water's surface when running at speed. More on that later in this gallery.
