42105

LEGO Technic 42105, Catamaran, represents a twin hulled sailing boat within the Technic theme. Released in 2020, the set contains 405 pieces and presents a nautical subject through a Technic style build, with no minifigures included.

Set 42105 brings a catamaran into the LEGO Technic theme, focusing on a maritime subject rather than the road vehicles and construction machines often associated with the line. No separate licence is identified in the supplied facts, so the set is best placed simply within Technic.

The build uses 405 pieces and concentrates on the recognizable layout of a catamaran, with two hulls and a connecting central structure. It includes no minifigures, and no named characters are listed. The contents are therefore centred on the model itself, its nautical outline and the structural building approach expected from Technic.

Catamaran can be used as a display model, for play built around a boat, or as part of a Technic collection that covers different kinds of vehicles and machines. Compared with other Technic sets, its main distinguishing point is the choice of a boat subject, rather than a car, motorcycle, truck or work machine.
