Ketch Pair is a type of sailing vessel that has two MASTS. The term 'ketch pair' refers to the two MASTS, which are usually shorter than those of a traditional ketch. The MASTS are typically arranged in a V-shape, with the forward mast being slightly taller than the aft mast. This arrangement allows for greater maneuverability and stability in rough seas. Ketch pairs are often used for recreational sailing, as they provide a comfortable ride and are easy to handle.
