It was made for boat operators Hobbs of Henley and the Hobbs family still owns it, remarkably. It is mahogany on oak frames.
A new feature at the show was a bunch of Stirling engine fans. Stirling engines are the power plant of the future and always will be. They are theoretically highly efficient, totally silent and completely reliable, but they are fantastically complex and have never taken off. The Swedish navy had some Stirling-powered submarines but that is about it.
The Stirling engines propelled boats round the lake in eerie silence, but the engines themselves were clearly works in progress, not designed to be lovely and old-fashioned like the steamers at the show.
By the way, by a nice coincidence the performances of a Stirling engine is indicated by its Beale number.
Which gives me an excuse to show you a photo of the wonderful boat-tailed car on the Henwood and Dean stand, as usual.
