Yacht Adventure (LEGO 42664)

About this set

This is LEGO Friends Yacht Adventure, set 42664, with 685 pieces and a difficulty of 3/5. It sits in the vehicle category but the subject is a sailboat, and the box carries the LEGO Friends and Friends series markings. The finished model is a yellow, blue, white and green sailboat, and the standout feature is the large sail. Build the hull first, then stand the mast and attach the sail, because flipping the boat with the sail already mounted can bend the sail panels. A slide runs along one side of the deck; its supports and railing connections are thin, so line up the clutch points before pressing to avoid repeated disassembly. Round portholes line the hull sides, and their frames contrast with the hull, so keep them facing the same direction. The set includes a dolphin and minifigures; place the dolphin beside the hull at water level and the figures on deck or at the top of the slide to sell the scene. At 685 pieces this is a mid-to-large Friends build, and the 3/5 rating comes from small symmetrical repeats such as the portholes and railings on both sides, which you can build in parallel to save sorting time. It suits builders who have finished smaller Friends sets and want a sail-and-slide structure, or anyone into ocean themes happy to spend two or three evenings on it.
