Anybody know what design this is? Appears to be deck stepped mast and low bow tank . B

Its a Nice Legs design, Ian Holt design, G Winder built, see previous thread for more info

Only one built to this design I believe.

From the design guide:

"Rudely described as a cross between a Ford Sierra and an aircraft carrier, this boat was a complete break from the current fashions in the fleet. Very full in the bow, high freeboard and a huge foredeck created by having the maximum beam well forward where the crew sits, finished off with a bustle in the run aft. All this had the rest of the fleet scratching their heads in disbelief. This was not helped by having a large radiused traveller on the foredeck for a self-tacking jib. Initially slow, the boat became gradually faster throughout its life and had a good championship at Whitstable in 1989 in the hands of its builder, Guy Winder, six years after its launch. Like most of Ian's designs, it did better in strong winds. "
