Paul,  The aircraft wing mounted vertically toact as a sail reminds me of the Clifton Flasher which took part in the John Player world speed sailing record attempt in POrtland harbour  the year that Timothy Coleman Won with his flying proa Crossbow, and doctor Gronogo was sailing an experimental catamaran with an aerofoil mast. That was a fascinating event with sailing craft lifting up on to hydrofoils, and sailboarders overtaking my car going from Portland to Weymouth, which reminds me, there is a theory that the foresail on a bermuda rig boat acts just like the slotted leading edge of an aircraft’s mainplane directing the airflow over the main aerofoil  giving considerably greater lift. We haven’t got round to blown flaps yet in boats, but I have seen an air compressor employed to blow a curtain of bubbles out at the bow to create a boundary layerwhich reduces the drag of the hull as it cuts through the water thus increasing the boat’s speed for a given power input. I remember putting some of this to the test when I was racing sailing dinghy’s, and certainly the boat went fastest when the foresail was trimmed so that the trailing edge was not flapping. p.s. The Clifton Flasher had four or five aerofoil wingsvertically arranged like a venetian blind, and she did not hang about either, it was a very good boat, a likely subject for a  very interesting model

As this thread is coming up for its 5th Anniversary I wonder if anyone is still looking for details on the Vic Smeed "Wing Ray"? Or perhaps our recently, accidentally aquired yacht is the last in existence?

We have one almost complete sheet of plans (unsure if there would have been more than one page?) and a more-or-less complete Yacht with 3 sails.

Currently starting restoration (Which will include changing the sail colour to something a little more 'period'

Could this be the last!
