, Serenity's Dream is a spring-powered wind-up craft able to execute a series of tacking maneuvers for up to 4m across a flat surface. To operate, set the Start/Stop switch, located on the roof of the cabin, to the "Stop" position. Remove the winding key from the foredeck, insert it into the ratchet mechanism located on the starboard hull and give several twists. Replace the winding key in the deck, place the boat on a flat surface, flip the Start/Stop switch to the "Start" position, and watch as your yacht sails off, executing a set of graceful, zig-zagging tacking maneuvers.
The Serenity's Dream 3D puzzle wooden sailboat model has 365 parts and is rated "Medium" difficulty, so it's a good build for modelers with a bit of experience.
