A very intersting and "living" musuem - highly recommended!

"The SR.N6 (Saunders-Roe Nautical 6), or Winchester Class hovercraft, was a stretched version of the SR.N5.
It was the first production hovercraft to be used in commercial service. It is powered by one Rolls-Royce Gnome engine used for both lift and propulsion.
At The Hovercraft Museum, you are able to see three different examples of the SR.N6 craft including the original prototype (009) operated by Hovertravel in the Solent, a military landing craft
variant and a stretched “Twin Prop” (Super 6) variant that is the oldest operational hovercraft in the world.
