Anotations

Scope note:

Two-masted, fore-and-aft-rigged sailing vessels with the smaller, mizzen, mast set forward of the rudder post; in use since the mid-19th century. For similar craft, but square-rigged on both masts and in use from the late 17th century until the early 19th century, use "ketches (square-rigged vessels)." For similar fore-and-aft-rigged craft with the mizzen set abaft the rudder post, use "yawls (sailing vessels)."
