I'd refute canard or reverse three pointers are "bad" design or unstable. Ones without dead rise do have problems though, but there are many that have been successful, even going around corners!!
Ted Jones DID invent prop riding, he approached Sayres with the idea before he had built a boat to test it, the idea was as he said "in my head". And bare in mind, Ted Jones was not a boat designer or builder, although his idea was to have the CoG quite far forward to get the stern up and out, supported by an air cushion, but as luck would have it, the prop hub did the job.
Miss England II. I pilot, Segrave, and two mechanics, Wilcox and Halliwell, one for each Rolls-Royce R type. After Segrave's deaath, as Ernie says, refurbished for Donn to use and destroyed when the storage warehouse was hit by an incendary bomb, so NOTHING left. The science museum has a propeller, but only because it was a spare. The Windemere Steamboat museum has Segrave's wicker seat from his accident, and the steering wheel is in a private chapel in Italy in all it's bent up glory. Though Bugattis have been "restored" from a wheel nut found in a pond before now!
I'm signed to secrecy on Crusader and it's successor but I can answer the point regarding materials and how the Vulcan was flown for the first time when Crusader was built, yet I stated it was ahead of the materials and construction techniques of the time. It was 1950, post war Britain. Vospers had to get a construction license to build Crusader. Materials were still short and there was only so much that could be made available. The Vampire was built in a similar way to Crusader (or vice aversa) with wood and alloys. The Vulcan was a goverment project, so an all ali airframe wasn't going to be a problem really was it!!
I have letters where requests for some special materials for Crusader, and some construction help is turned down by the Ministry of Supply, so I stand by my remark, as it's researched and has documentation to prove it, Vulcan or not!
Finally, did you know that once the first model tests of K7 were proved successful, the idea was to move the forward sponsons to the stern and the rear shoe to the bow? Wasn't done because of the lack of money. Again, I have this is someones own handwriting, someone involved in both Crusader and K7.
