A yawl is a two-masted, fore-and-aft rigged sailboat characterized by a smaller mizzenmast stepped aft of the rudder post. Known for balance and easy handling, the small mizzen sail helps control the helm and provides stability, making it popular for cruising. It is distinguished from a ketch by the mizzen's position behind the rudder.

Key Characteristics of a Yawl
Two Masts: Features a mainmast (forward) and a much smaller mizzenmast (aft).

Rudder Position: The defining feature is that the mizzenmast is located behind the rudder post, often at the extreme stern of the vessel.

Sail Configuration: Typically rigged with a mainsail, jib/staysail, and a mizzen sail.

"Air Rudder": The mizzen sail acts as an "air rudder," allowing the sailor to balance the boat's helm efficiently, especially in heavy weather.

Functionality: They are considered excellent, versatile cruisers for both coastal and, in larger sizes, ocean sailing.

"Rule Beaters": Historically, many were designed with this rig to gain advantages under various racing rules.
