This is the first Prospect of Whitby designed and built for Arthur Slater. She was designed to the R.O.R.C Rule, and constructed of wood by Bjarne Aas of Fredrikstad, Norway. Aas was a naval architect in his own right, building many of his own designs. He is best known for his International One Design Class design. His yard did not survive the transition to fiberglass construction.
An interesting feature of this design is the rather marked "toe" low down in the forefoot and the straight line forming the bottom of the keel, which are somewhat unusual for any S&S design but were required by the owner to ease the problem of keeping the boat in a harbor that dries out at low tide.
Here are the plans.
Displacement 22,080 lbs
Ballast 11,000 lbs
