William Atkins - Maybe Tally Ho design.
Hess's BCCs were a variation on the olde Bristol Pilot Cutter. There was no rigid spec for a BPC although they all had relatively straight stems and a long full keel. Usually wine glass stern but not always as bluff as the Hess type. Often had a few feet of overhang at the stern.
Indeed, this is a Cape George 31, which was derived (by Carl Chamberlain) from Atkin's Tally Ho. I give it to TDW. By the way, Cape George now builds the BCC and FCC.
"Tally Ho! is 30 ft. l.o.a., 28 ft. l. w. l., 9 ft. beam, 5 ft. 6 in. draft. Her sail area is 672 sq. ft. There is 6,600 Ib. of iron in her keel, with 2,000 Ib. of cement ballast inside and 1,000 Ib. of lead for trimming. The yacht's displacement is 20,800 lb."
I think if you examine Hess's BCC you'll see that it is very similar to Atkin's Fore N Aft:
"Fore An' Aft is 28 feet 8 inches in over all length, has a water line length of 27 feet, a breadth of 9 feet 6 inches, and a draft of 5 feet 2 1/2 inches. Her displacement, loaded for a cruise, is 19,200 lbs. Light displacement (2 in. above L.W.L.) is 16,900 lbs."
