The Tasmanian One Design is a class of Australian sail boat.
In February 1900, The Rudder magazine published plans, by William Hand Jr, of a "knockabout".
[1][2] Webster had Hand's design modified, by Hobart naval architect Alf Blore, to suit local sailing conditions and boat building practice and by 1911 had persuaded several yachtsman to build identical yachts.
The first, Pacific, was built by T Le Huquet in 1914 for Frank Rule, a Tasmanian.
Eventually outclassed by the later and larger "A-Class" yachts in the 1920s and 1930s, and too large for the "B-Class", Vanity and Weene were simply cut in half and lengthened to once again lead the fleet.
