The LEGO Technic Emirates Team New Zealand AC75 Yacht (Set #42174) is a 962-piece advanced building set designed for adults, recreating the iconic AC75 racing yacht used in the America's Cup. The AC75 is a 23-meter monohull racing yacht featuring wing-like sailing hydrofoils, a soft wingsail, and no keel — the hydrofoils act as underwater wings that lift the hull clear of the water to reduce drag and achieve extraordinary racing speeds.

This detailed model captures the engineering complexity of the real yacht through authentic LEGO Technic mechanisms. A working pneumatic system, operated via external cranks on the side of the hull, pumps up the hydrofoil cant arms exactly as the crew would on the actual boat. The model also features a rotating mast with rigging, functional mainsheet and jib sheet controls, and impressive foil arms and foil wings. Two large printed skin sails are included, placed back-to-back to create an authentic 3D sail shape.

The completed model stands over 68 cm (27 in.) high, measures 56 cm (22 in.) long and 33 cm (12.5 in.) wide. An integrated display stand is built into the model structure, making it an impressive shelf piece for adult LEGO fans and sailing enthusiasts. The 205-step build spans 6 numbered bags of parts and introduces several new mold elements unique to this set, including oversized foil sheet sails. Recommended for ages 18 and up.
