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:
“It was a poetic recreation to watch those distant sails steering for half-fabulous ports, whose very names are a mysterious music to our ears.... It is remarkable that men do not sail the sea with more expectation. Nothing was ever accomplished in a prosaic mood.”
—Henry David Thoreau (1817–1862)
