Screw Sloop

A screw sloop (ScSlp) is a propeller-driven sloop-of-war. In the 19th century, during the introduction of the steam engine, ships driven by propellers were differentiated from those driven by paddle-wheels by referring to the ship's screws (propellers). Other propeller-driven warships included screw frigates and screw corvettes.

    But screw your courage to the sticking-place
