What it is

A boat propelled by a jet of water expelled above the waterline, able to navigate very shallow braided rivers. Water-jet propulsion is used today in fast ferries and naval vessels.

Water-jet propulsion had been trialled before (Campini, 1930s); Hamilton produced the first practical system.

What it led to

  • navigation of shallow braided rivers
  • water-jet propulsion in fast ferries
