LEGO Technic Catamaran 42105 Building Set, 404 Pieces
Build, rebuild, and set sail with the LEGO Technic Catamaran. This 404-piece model introduces the mechanics of a racing sailboat through moving sails, adjustable dagger boards, and a steerable rudder. Its two-hull design is made for hands-on discovery, and the build can be reconfigured into a Race Power Boat for a second way to play. At over 12 inches long, the finished model offers enough presence for display while remaining designed for handling in a bathtub. It is a thoughtful choice for builders who enjoy vehicles, movement, and engineering-led projects.
