Naramatac was a catamaran sailboat designed by Robert B. Harris in 1948 [1] [2] and launched in 1950. [3] Its innovative use of asymmetric hulls later became a hallmark of the Hobie Cat. [5] [1]
I was looking for a day sailer which, though not necessarily a speed demon, would easily go by other boats of her size, would manoeuvre well and go to windward. I also paid some attention to making her easy to build with thoughts for the home builder.
Harris' design was not entirely successful, however. At speed the flat bottoms pounded, and it showed poor performance in low wind which he ascribed to deep hulls (particularly aft), lack of stability to carry additional sail, too much wetted surface, and too heavy construction. [1]
While the trials of Naramatac demonstrated her speed to be proportional to Manu Kai and proved that a small catamaran was practical, they also showed that she was sluggish in maneuver, slow in light to moderate winds, had far too much longitudinal motion, and lacked stability due to excessive narrowness in hull spacing.
A multihull is a ship or boat with more than one hull, whereas a vessel with a single hull is a monohull.
A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture.
A catamaran is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. 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.
A point of sail is a sailing craft's direction of travel under sail in relation to the true wind direction over the surface.
Proas are various types of multi-hull outrigger sailboats of the Austronesian peoples. The terms were used for native Austronesian ships in European records during the Colonial era indiscriminately, and thus can confusingly refer to the double-ended single-outrigger boats of Oceania, the double-outrigger boats of Island Southeast Asia, and sometimes ships with no outriggers or sails at all.
Capsizing or keeling over occurs when a boat or ship is turned on its side or it is upside down in the water. The act of reversing a capsized vessel is called righting.
The Hobie Cat is a small sailing catamaran manufactured by the Hobie Cat Company. Hobie's line of products includes surfboards, sailboats, kayaks, stand-up paddle boards, and pedalboards, although the Hobie Cat Company is known worldwide for its catamarans. Hobie also designed a successful monohull, the Hobie 33.
A beachcat is an off-the-beach class of catamaran ("cat") sailboat.
The turbosail or French turbovoile is a marine propulsion system using a sail-like vertical surface and a powered boundary layer control system to improve lift across a wide angle of attack. This allows the sail to power the boat in any direction simply by moving a single flap at the back of the sail, unlike conventional sails which have to be continually adjusted to react to changes in the relative wind.
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 twice the wind speed.
Drua, also known as Na Drua, N'drua, Ndrua or Waqa Tabu, is a double-hull sailing boat that originated in the south-western Pacific islands. Druas do not tack but rather shunt. Both ends of each hull are identical, but the hulls are of different sizes and the smaller one is always sailed to windward. The main differences, compared to proas, are that the hulls have a symmetric U-form profile, and a second hull is used instead of an outrigger. When a float (cama) is used in place of the smaller hull, the craft is called a camakau.
The Fijian double canoe was the largest and finest sea-going vessel ever designed and built by natives of Oceania before contact with Europeans.
A sailing yacht, is a leisure craft that uses sails as its primary means of propulsion. A yacht may be a sail or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies here to sailing vessels that have a cabin with amenities that accommodate overnight use. To be termed a "yacht", as opposed to a "boat", such a vessel is likely to be at least 33 feet (10 m) in length and have been judged to have good aesthetic qualities. Sailboats that do not accommodate overnight use or are smaller than 30 feet (9.1 m) are not universally called yachts. Sailing yachts in excess of 130 feet (40 m) are generally considered to be superyachts.
The Topcat is a one-design sailing catamaran boat class which is divided into several boat sizes.
High-performance sailing is achieved with low forward surface resistance—encountered by catamarans, sailing hydrofoils, iceboats or land sailing craft—as the sailing craft obtains motive power with its sails or aerofoils at speeds that are often faster than the wind on both upwind and downwind points of sail. Faster-than-the-wind sailing means that the apparent wind angle experienced on the moving craft is always ahead of the sail. This has generated a new concept of sailing, called "apparent wind sailing", which entails a new skill set for its practitioners, including tacking on downwind points of sail.
Forces on sails result from movement of air that interacts with sails and gives them motive power for sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and sail-powered land vehicles. Similar principles in a rotating frame of reference apply to wind mill sails and wind turbine blades, which are also wind-driven. They are differentiated from forces on wings, and propeller blades, the actions of which are not adjusted to the wind. Kites also power certain sailing craft, but do not employ a mast to support the airfoil and are beyond the scope of this article.
James Wharram was a British multihull pioneer and designer of catamarans.
Robert B. Harris was an American multihull sailboat designer.
Kaep is a traditional type of double-ended Proa sailboat native to Palau. Some of the essential design elements have also been adopted as a modern smaller multihull prototype variant.
Miss Nylex is a C-Class racing catamaran, designed and built in Australia in the 1970s specifically to compete in the International Catamaran Challenge Trophy (ICCT). It has a single wingsail with two aerodynamic flaps, instead of the conventional mast and sail combination.
The Hobie Bravo is an American catamaran sailing dinghy that was designed by Hobie Cat in 2000 and first built in 2001. The design is intended for sailing from beaches by one or two people.
