A traditional Tamil catamaran on a Chennai beach.

A catamaran is a type of boat (or occasionally ship) consisting of two hulls joined by a frame. Catamarans can be sail- or engine-powered. The word catamaran comes from the Tamil language, in which the word kattumaram means "logs bound together". The catamaran was the invention of the paravas, an aristocratic fishing community in the southern coast of Tamilnadu, India. Catamarans were used by the ancient Tamil Chola dynasty as early as 5th century AD for moving their fleets to conquer such Southeast Asian regions as Burma, Indonesia and Malaysia.

Although the principles of sailing are the same for both catamarans and monohulls, there are some "peculiarities"to sailing catamarans.

  • Catamarans can be harder to tack (turn through the wind). Because they are lighter in proportion to their sail size, they have less momentum to carry them through the turn when they are head to wind. Correct use of the jib sail is often essential in successfully completing a tack without ending up stuck in irons (pointing dead into the wind and sailing backwards).
  • They have a higher average speed.
  • All boats sail faster when travelling in certain directions relative to the wind with the best speeds typically being achieved when heading away from the wind at about 135 degrees. This effect is much more noticeable with catamarans, even to the extent that it can be more efficient to jibe ('tack' downwind) in zig zags, rather than heading directly away from the wind as a monohull would.
  • Catamarans are less likely to capsize in the classic 'beam-wise' manner but often have a tendency to 'pole-axe' (or 'pitchpole') instead - where the leeward (downwind) bow sinks into the water and the boat 'trips' over forward, leading to a capsize.

Teaching for new sailors is usually carried out in monohulls as they are thought easier to learn to sail, a mixture of all the differences mentioned probably contributes to this.


Catamarans, and multihulls in general, are normally faster than single-hull boats for four reasons:

  • each hull of a catamaran is (typically) thinner in cross section than those of monohulls;
  • catamarans are lighter due to the fact there is no keel counterweight.
  • catamarans have a wider beam (the distance from one side of the boat to the other), which makes them more stable and therefore able to carry more sail area per unit of length than an equivalent monohull.
  • the greater stability means that the sail is more likely to stay upright in a gust, drawing more power than a monohull's sail which is more likely to lean over.

Catamarans are especially favourable in coastal waters, where the open spaces permit the boat to reach and maintain its maximum speed. Catamarans make good cruising and long distance boats: The Race (around the world, in 2001) was won by the giant catamaran Club Med skippered by Grant Dalton. It went round the earth in 62 days at an average speed of eighteen knots. A fer is a large beam around which the hull of a ship is built. ...

Catamaran designs

Popular small racing catamaran sailboats include:

  • The Hobie cats (especially the 16-foot long Hobie 16, as well as many other designs including 14, 17, 18, and 20 ft models.)
  • Nacras
  • Prindles
  • International A-Class (open design; length 5.49 m (18 ft), beam 2.3 m (7 ft 6.5 in), weight 75 kg, sail 13.94 m² (150 ft²))
  • Formula classes (F16, F18, F20)
  • Dart 15 and Dart 18
  • Tornado, Olympic class racing catamaran.

Powered catamarans

A recent development in catamaran design has been the introduction of the power catamaran. The 'power' version incorporates the best features of a motor yacht and combines it with the traditional sailing characteristics of a multihull. Usually, the power catamaran is devoid of any sailing apparatus as demonstrated by one of the top-selling models in the United States, the Lagoon Power 43. This vessel has now been introduced to a number of charter fleets in the Caribbean and the Mediterranean and is becoming an increasingly common sight.


Mega catamarans

One of the biggest developments over the last decade in the yachting arena has been the rise of the super catamaran - a multihull over 60 feet in length which come in semi-custom and custom designs.


Various international manufacturers are leading the way in this area including Yapluka, Sunreef, Lagoon and Privilege. A catamaran over 145 feet in length is reportedly under construction on the Eastern Seaboard of the United States.


The emergence of the super or mega catamaran is a relatively new event which is akin to the rise of the mega or super yacht which was used to describe the huge growth in luxury, large motor yachts in the French Riviera and Floridian Cost.


It takes up to one year to complete construction of one of these super catamarans and represent state-of-the-art design breakthroughs in the catamaran sector.
