KATTUMARAM became CATAMARAN in ENGLISH,,,,,

                                                    KATTUMARAM...........

A catamaran is a geometry-stabilized boat or ship. It is usually multihulled, consisting of two hulls, or vakas, joined by some structure, the most basic being a frame, formed of akas. Catamarans can be sail- or engine-powered.

The word catamaran is derived from the Tamil word kattumaram (கட்டுமரம்), literally "tied wood". Kattumaram refers to a geometrically-stabilized rowboat design popular among the Dravidian people. Its parts are usually referred to by the corresponding part-names of theProa, a geometrically-stabilized sailboat design popular among the Oceanic people.

Catamarans are a relatively recent introduction to the design of boats for both leisure and sport sailing, although they have been used since before recorded history among theDravidian people, in South India, and independently^{[citation needed]} in Oceania, wherePolynesian catamarans and outrigger canoes allowed seafaring Polynesians to settle the world's most far-flung islands.

In recreational sailing, catamarans, and multihulls in general, had been met by a degree of skepticism from Western sailors accustomed to more "traditional" monohull designs,mainly because multihulls were based on, to them, completely alien and strange concepts, with balance based on geometry rather than weight distribution. However, the catamaran has arguably become the best design for fast ferries, because their speed, stability and large capacity are valuable.
