Inventions full of promise. In the 1950s a British inventor seemed to have a solution to a lot of transport problems. How to travel at speed over a variety of surfaces. Christopher Cockerell, like so many inventors of the past, had difficulty in convincing people of the usefulness of his invention. He persisted and the commercial Hovercraft was born.
It’s not that traveling on a cushion of air had never been considered before. It’s more a question of the fact that it took until the 20th century for all the components (engines and materials) to become available to make a practical vehicle.
It’s not a boat. It’s not a plane. It’s an air-cushion vehicle. Underlying this is the question of who takes responsibility for these vehicles? I know this with reference to those who I have worked with over the years. In the 1990s, it was the Civil Aviation Authority (CAA) that issued a Certificate of Airworthiness for these craft. Today, they are addressed under marine regulation.
The backward and forward of the arguments as to what a “Hovercraft” is defined as, surprisingly goes on at length. It’s flexibility in being able to rapidly traverse water and land without alteration is an asset but a minefield for lawyers[1].
Yesterday, I took the passenger Hovercraft service between Southsea (Portsmouth) and the town of Ryde on the Isle of Wight. It’s the fastest way to get from the mainland to the island. 10 minutes across the water.
This for me was to revisit a trip that I often made in the 1990s. I’d drive down from London Gatwick early in the morning. Try to fit a breakfast in before taking an early Hovercraft across to the Isle of Wight. Memories of arriving at a desolate car park in the cold and wet stuck. There I’d be picked up and ferried to Britten-Norman[2] for the day. The Britten-Norman aircraft company had its headquarters in Bembridge.
Although the Islander is a small aircraft its owners liked to equip it with an array of different modifications. My job was the approval of modifications. All done, at the time, under British Civil Airworthiness Requirements (BCARs). It was one overseas mission I enjoyed a lot.
