Runa IV is currently undergoing work in Brest, France. She appears to have been rigged as a yawl, either at birth, or at least before 1920. In this respect, as well as her size, she sets herself apart from her siblings. In 1937 it is known there was a swedish Albin inboard motor in her, although I don't know whether or not this too was a later modification.
From 1937 until 2009 she lay in or around San Francisco I believe, where she raced until at least 2008. Although it is likely she was rigged as a gaff yawl in 1918, with or without her mizzen, in 2009 she had been rerigged as a marconi sloop, her bow sprit absent.
The wonderful Kongelig Dansk Yachtklub have sent copies of their year books where we can read about the boats and their rigs. (below)
So Runa IV was a yawl in 1919.
