Ketch mizzen sheet. So on a ketch, the dual purpose of the mizzen sail is to both propel and balance the vessel, while on a yawl, the smaller mizzen mainly serves the purpose of trim or balance. Yawls tend to have mainsails almost as large as those of comparable sloops. A ketch may be distinguished from a cutter or a sloop by virtue of having two masts rather than one, though a ketch with two foresails is sometimes called a "cutter-rigged ketch". Both the ketch and the yawl differ from the two-masted schooner, whose aft mainmast is taller than the foremast.
Ketch set on a ketch. The "Scarlet Queen" was a 78-foot ketch with a white hull, teak decking, brass bright-work, and sporting the "Scarlet Queen" herself, on the bowsprit, naked as the day she was born, "a fresh, young body... looking forward, ... bold, teasing... dressed in only a crown, and painted brilliant red." A William Garden–designed Formosa 51 ketch named "Wanderer" was the main setting in the 1992 film "Captain Ron". Three Formosa 51s were used in filming. A Formosa 51 ketch named "Viking Spirit" was used in the 2004 romantic comedy "50 First Dates" starring Adam Sandler and Drew
