42105 Catamaran

42105 Catamaran is a TECHNIC set that was released on January 2, 2020.
==Background==
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.
Catamarans were invented by the Austronesian peoples which enabled their expansion to the islands of the Indian and Pacific Oceans.
Catamarans range in size from small (sailing or rowing vessels) to large (naval ships and roll-on/roll-off car ferries). The structure connecting a catamaran's two hulls ranges from a simple frame strung with webbing to support the crew to a bridging superstructure incorporating extensive cabin and/or cargo space.
