The design of Dyarchy has been envied and admired throughout the world. Her reputation was gained purely as a beautifully conceived cruising boat both in function and appearance. In 1987 the designs were prepared for hull number 7 which was built in steel by her owner at Calshot on Southampton Water, the venue of the 1927, 1929 & 1931 Schneider Trophy air races.
The comprehensive and complete set of revised and updated drawings include details of the transversely framed steel hull, steel deck and deck works and construction details of the rudder, chain plates, mast fittings, engine beds and steering arrangements. The interior layout was modified from Pickney’s original, but the rig and deck arrangement remains largely the same.
We offer individual copies of the original building plans for the steel Dyarchy as well as the original carvel (design number 0037) and also contemporary drawings for WEST strip plank construction (design number 1187).
