Gosh you have all gone very quiet - ok well as my vesion of this rig will be on display at the MYA AGM tomorrow i will give you the answer - the boats name is “KESTEREL”
My version of this rig i have called “Prop-a-Footy”
And now the interesting bit - This boat is an autogiro, which means that its blades ae not connected to a water propeller - the blades are being used the same way as a sail.
This is the earliest autogiro boat and I think that we can safely credit Lord Brabazon with the original concept of using the blades like this to drive a boat directly, since all the other people before him had only thought of using the turbine to drive a propellor. After all, the aircraft autogiro was only invented a couple of years earlier in 1930.
KESTREL, is an 1896 Bembridge Redwing. This class has an unlimited sail plan - you can do whatever you like as long as the area is less that 200 sq. ft. So Lord Brabazon tried a whole lot of different sail rigs, including this one, which had a blade area of only 30 sq ft. King George V, who knew a lot about yachts, said “I have never seen a yacht sail so close to the wind”.
Unfortunately, there was an accident in Cowes Harbour - Lord Brabazon shouted out “Let her go”, and his crew let go of the rotor instead of the boat, and then it could not be stopped, because the brake wasn’t strong enough. It was eventually stopped, after demolishing the next boat along. The moral of this tale is that you should be a bit more specific when giving instructions to your crew.
Lord Brabazon then got involved in some other project, so the boat lay in a shed for 60 years until it was restored by a classic boat enthusiast named Maurice Wilmot, who has had it put back exactly as it was in 1933, except that it now has a stronger brake on the rotor. This restoration was done by the process of removing each bit of wood and replacing it with an identical new bit of wood. Maurice Wilmot has a collection of restored old boats, including other Redwings.
The KESTEREL is now fully restored and being used regularly at Cowes and housed at the classic bat museum on the Isle of Wight. Here is a video of it in action.
