Hovercraft
From Tardis Wiki, the free Doctor Who reference
Hovercraft were amphibious vehicles.
Jo Grant and John Hart used a Royal Navy hovercraft to escape from some Sea Devils; Jo was able to drive it. The Doctor and the Master were picked up by the hovercraft after the destruction of the Sea Devil base.
The Master hypnotised a sailor to pose as him while he escaped in the craft. (DW: The Sea Devils)
The crew of a Delta III refinery used a hovercraft to travel through the swamps. (DW: The Power of Kroll)
