A ketch is a two-masted, fore-and-aft rigged sailing vessel characterized by a taller mainmast forward and a shorter mizzenmast (jigger) stepped forward of the rudderpost. This design divides the sail area, offering flexible, easily managed sail plans for handling heavy winds and providing improved balance for long-distance cruising, often preferred in classic yacht designs.

Key Characteristics and Features:
Rigging: Features a mainmast and a shorter mizzenmast located in the stern.

Mizzen Placement: The key distinguishing feature is that the mizzenmast is stepped forward of the rudderpost, differentiating it from a yawl.

Performance: The divided rig provides a lower center of effort, making it ideal for cruising and manageable in high winds, though it may not sail as fast or as close to the wind as a sloop.

Handling: The versatility of the sail plan—main, jib, and mizzen—allows for easy balance, making it popular for shorthanded sailing and long-distance travel.
