Nova Scotia became a world leader in both building and owning wooden sailing ships in the second half of the century. Nova Scotia produced internationally recognized ship builders Donald McKay, John M. Blaikie and William Dawson Lawrence and ship designers such as Ebenezer Moseley as well the propeller inventor John Patch. Notable ships included the barque "Stag", a clipper renowned for speed and the ship "William D. Lawrence", the largest wooden ship ever built in Canada. Mariners such a Capt. George "Rudder" Churchill of Yarmouth became famous for their voyages. The province also produced a notable 19th-century female mariner, Bessie Hall from Annapolis Royal. The most famous of the sailors from Nova Scotia was Joshua Slocum who became the first man to sail single-handedly around the world (1895). Competition from steamships in the late 19th century ended the Golden Age of Sail, although the legacy continued to inspire mariners and the public into the following century with the many racing victories of the Bluenose schooner.
