Annular Sails
A few mills had annular sails, forming a circle. These sails utilised the patent system, enabling adjustment to be made without stopping the mill. One example of a mill with annular sails was at Feltwell, Norfolk. Others are known to have existed at Haverhill, Suffolk, Boxford, Suffolk and Roxwell, Essex. Annular sails were also employed on large wind engines, such as the Titt engine at Crux Easton, Hampshire.

Famous quotes containing the word sails:
“She smiled and that transfigured me
And left me but a lout,
Maundering here, and maundering there,
Emptier of thought
Than the heavenly circuit of its stars
When the moon sails out.”
—William Butler Yeats (1865–1939)
