S/Y Thea - Design no. 206

Thea was designed and build by Johan Anker in Norway in 1918, and was one of the first yachts to be rigged with bamuda rig.

Thea was originally build according to the "S-Formula", valid in Scandinavia. A rule proposed by J. Anker himself in 1916, as a change to the First International Meter Rule from 1907. 

These changes to the rule led to the The Second International Rule in 1919. Since then Thea was, along with the other S-Formula yachts, converted and rated as a 12mR S.I. (Second International rule)
