In 1935, a Bristol, Rhode Island naval architect named Sidney Herreshoff (you may recognize the family name, as he was Capt. Nat's eldest son) drew the plans for a fun little number called the AmphiCraft, a 13-foot-1-inch trailerable vessel that could be fitted with an outboard, rowed, or sailed. For sailing excursions, this beamy little daysailer was rigged as a catboat with a free-standing spar and a wishbone.

Rig sound familiar?

From the AmphiCraft and the Ljundstrom rig in the '30s, the Freedom 40 in '76, through the later 'wishbone' Freedoms . . . to the Wylies and the Taunton 40 and to . . . ?

LJUNDSTROM RIG

Looks like a standard genoa, only it is 2 genoas that are lying flat against each other when sailing to windward, and they open 'wing and wing' when sailing down wind. Often used on blue water sailboats, the sheets can be led back to the tiller to automatically steer down wind. The "So Do It" class used this as their only sail.

Redwing:
The hull design of the Bembridge Redwing has changed three times in their 104-year history and the class is known for its experimentation with rig design. The freedom of rig design was retained and experiments continued with different sail plans. Uffa Fox designed a narrow, tall bermudan rig for IBIS in 1937-8, and the Ljungstrom rig, involving a revolving unstayed mast around which the sail was rolled was also tried ( the latter sounds not unlike the rig in THE WHITE CAT 30 4 ).


In 1972, Dr. Jerry Milgram's 37 ft / 11 m cat-ketch CASCADE was an exciting evolution, revolution, and inspiration to many sailors ! http://vault.sportsillustrated.cnn.com/vault/article/magazine/MAG1087128/index.htm
