Hovercraft

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 Third 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) As it was a very conspicuous form of transport, the Master abandoned it a short distance down the coastline. (EDA: The Eight Doctors)

Lupton used a hovercraft while being chased by the Third Doctor, after stealing the Metebelis Crystal. (DW: Planet of the Spiders)

The crew of a Delta III refinery used a hovercraft to travel through the swamps. (DW: The Power of Kroll)

Jo Jones and her grandson Santiago Jones were due to take a hovercraft as transport to Norway. (SJA: Death of the Doctor)
