Yeah the extreme drifts/sweeps on sheers really became a hit in the late 1920s to the 1930s. It would be interesting to see if you could incorporate it into a modern shape. If you are interested in boats of that time there was a great book called The Golden Century-classic motor yachts 1830-1930 by Ross MacTaggart. Great pictures and drawings. Another book of boats from the same time from the yards of Silvers a Scottish company. Motor Yacht Building by John Bain.
