A catamaran is a watercraft with two parallel hulls of equal size. The distance between a catamaran's hulls imparts resistance to rolling and overturning. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes.
The ISAF International Class Hobie 16 (H16) is a popular catamaran manufactured by the Hobie Cat Company for racing and day sailing. The craft was the driving force behind the popularization of beachcats and was recently inducted into the Sailing Hall of Fame.
Hobie Cat is a company that manufactures watercraft and other products as the Hobie Cat Company. "Hobie Cat" can also refer to specific products of the company, notably its sailing catamarans. Its fiberglass catamaran models range in nominal length between 14 feet (4.3 m) and 18 feet (5.5 m). Rotomolded catamaran models range in length between 12 feet (3.7 m) and 17 feet (5.2 m). Other sailing vessels in the Hobie Cat lineup include, monocats, dinghies, and trimarans, ranging in length between 9 feet (2.7 m) and 20 feet (6.1 m). Its largest product was the Hobie 33, 33 feet (10 m) in length. The company's non-sailing product line includes surfboards, kayaks, stand-up paddle boards, pedalboards, eyeware, and e-bikes. It was founded in 1961 by Hobart (Hobie) Alter, who originally manufactured surfboards.

The term beachcat is an informal name for one of the most common types of small recreational sailboats, minimalist 14 to 20 foot catamarans, almost always with a cloth "trampoline" stretched between the two hulls, typically made of fiberglass or more recently rotomolded plastic. The name comes from the fact that they are designed to be sailed directly off a sand beach, unlike most other small boats which are launched from a ramp. The average 8 foot width of the beachcat means it can also sit upright on the sand and is quite stable in this position, unlike a monohull of the same size. The Hobie 14 and Hobie 16 are two of the earliest boats of this type that achieved widespread popularity, and popularized the term as well as created the template for this type of boat.
A sailing hydrofoil, hydrofoil sailboat, or hydrosail is a sailboat with wing-like foils mounted under the hull. As the craft increases its speed the hydrofoils lift the hull up and out of the water, greatly reducing wetted area, resulting in decreased drag and increased speed. A sailing hydrofoil can achieve speeds exceeding double and in some cases triple the wind speed.
Randolph L. Smyth is an American competitive sailor and two-time Olympic silver medalist.
