Hi, I see that the Brum Scott with launch sidecar that was at the Rally is now for sale on eBay at £9995-00.
For a video of the sidecar in use as a launch see ‘Cordless Canoe Challenge 2013 at Beale Park’ on YouTube.
It reminds me very much of the much larger Canterbury Belle sidecar/boat from about 1960. There is a good Pathe film clip of that on YouTube. It was a two seater, powered by a J.A.P. front-mounted engine, with a long driveshaft back to the propeller. Now if some brave soul wanted to be particularly loyal to Scotts, and very masochistic, they could build one with a Cycauto engine!
