Mines somewhere in the loft I will try and find it however; re qualifications; one of my chess playing friends used to be a researc...

Re: Blue Bird K4

I'm in two minds about Du Cane's books. ... As an aside, would those with those books (I cannot find mine, house move) give me a list of Du Cane's qualifications, I fear I may have sold him short !! I think I know what you are saying. But considering the time when the book was published (1st in 195...

Re: Blue Bird K4

This has turned into a very interesting thread. Maybe of interest; Henry Fauber, a pioneer of powerboats, in 1908 submitted patents for a stepped hydroplane powered by a totally enclosed paddle wheel, essentially a drum with blades on it, in the centre of the hull. The boat was never built. 15 years...

Re: Blue Bird K4

Steve posted '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 ...

Re: Blue Bird K4

Bill, you may find this book very interesting. Loads of technical and engineering stuff. 'High speed small craft' by Commander Peter Du Cane. One of the reprints has an exploded view of Crusader in the back. Copies are available on Amazon or ABE Books. Massive amount of real heavy information about ...

Re: Blue Bird K4

Surface drives, part of the prop out of the water, were first tried by Albert Hickman on his sea sleds in 1916 -1919. Used on a boat called Rainbow in 1924. The roostertail is evident in photos of rainbow in 1924. 'Prop riding' boats really became evident in 1948 with Miss Canada 1V then Slo Mo then...

Re: Blue Bird K4

K4 was a three point hydroplane. Originally it planed with the bottom of the transom on the water(as designed). It was not a prop rider as such. Donald converted it to a prop rider after he had the jet engine removed.(his fathers experiment) Piston engine was refitted but moved forward. I think the ...
