"Crown of Germany  1869"

A form of rigging screw came into it's own for setting up the rigging of the new breed of large iron sailing ships.

Built of iron in 1869 with dimensions of 276' x 38' x 23' and 1744 tons net. By adopting four instead of three masts, and reducing the size of the spars, while retaining all the canvas necessary for propulsion, a great improvement was made. This became a very popular rig throughout the remainder of the nineteenth and the early twentieth centuries.
