Designed by George Cockshott, an amateur boat designer from Southport, over a century ago, the International Twelve Foot Dinghy became the first one-design racing dinghy to achieve international recognition.

George Cockshott[edit]

Was born May 7th. 1875, and educated at Uppingham and King’s College Cambridge. He resided at Southport, and was Vice-Commodore of Southport Corinthian Yacht Club. As a boy he took a keen delight in building and sailing model yachts, and while at school built for himself a rowing and sailing boat. He joined the Cambridge University Sailing Club shortly after its formation in 1893. On coming down from Cambridge, he spent several seasons as ‘forward hand’ racing in the Southport ¾-rating class and the Menai Straits 1-rating class. He owned the Unona, a half decked centre board boat, and designed and sailed for two seasons a boat in a ‘restricted class’ of 12-foot dinghies with a fair measure of success. In 1901 he became owner of the 12 ton cutter Eurynome, a boat long famous as a cruiser-racer in Irish, Clyde and Welsh waters, and though Mr. Cockshott preferred cruising to racing, considerably reduced her spars and canvas, she was successfully raced under his flag for several seasons in a strong handicap class. In 1904, he again entered the ¾-rating class as part owner of Imp. His present yacht is the Sthoreen, an able and comfortable cruising yawl of 16 tons, built from his own designs, and launched in the spring of 1906. Mr. Cockshott has also turned his attention to yacht architecture, and, in addition to his own yacht, one 20 tonner, several smaller yachts, and motor launches, and tender to the Southport lifeboat, have been built from his designs. He designed a new racing class for the West Lancashire Yacht Club from which six boats are now being built. Clubs: Royal Mersey Yacht Club, Southport Corinthian Yacht Club, West Lancashire Yacht Club, and Cambridge University Cruising Club. Address: 3, Tulketh Street, Southport.

B.R.A.[edit]

In 1913 there was published in England a new rating rule for yachts of all sizes. The rule was prepared by the self -styled 'Boat Racing Association' under the chairmanship of Lt. Col. J. T. Bucknill at a meeting in November 1912. B.R.A. felt that ordinary racing sailors were not catered for by the YRA (Yacht Racing Association) rating rules. Initially there was to be a class of 18 footer rating, which was to be smaller than a 6m. Other sizes of yachts were intended to follow, including a 12 foot and a 20 foot.

The B.R.A. rating formula was:

Rating in feet= (Length + Square root of sail area)divided by 4 + (length x square root of sail area) divided by 3 x cube root of weight.

I leave it to another contributer to do the mathematics.[1]

The future of the class[edit]

The foundations of the international association were laid at a meeting in the Hotel Jolanda, Portofino, Italy in May 2006 and this was followed by another meeting in Tuzla, Turkey in October 2007. During this time much progress has been made towards re-establishing the 12' Dinghy as a truly international class.

The 12 feet dinghy is one of the Vintage Yachting Classes at the 2012 Vintage Yachting Games.

The Dublin Bay Problem[edit]

In 2011 the first Irish 12 foot Championships for at least 40 years was held at the Royal St George Yacht Club. Boats of the International Design and the Dublin Bay option sailed against each other.

Dublin Bay 12 footer[edit]

Due to the type of short steep waves which occur in Dublin Bay, Ireland, some owners of the Dun Laoghaire International 12 footers under the recommendation of J.J. O'Leary, modified the design in the 1960s to reduce the amount of water taken over the bow. They modified the design by putting a small foredeck with washboards, inserting a new mast step aft of the existing step, cutting a circular hole in the forward thwart, moving the mast aft, shortening the boom, cutting down the size of the mainsail, and hoisting a small jib borrowed from the other Dublin Bay classic dinghy class the Water Wag. The modification was declared a success, and the modified fleet sailed and raced for about another 10 years. No alterations were made to the hull, or underwater appendages - so the alterations should be reversible.
