Get ready for an unparalleled boat model building adventure! Inspired by classic scientific documentaries and biographies of outstanding marine explorers, the research vessel building kit for adults conveys the might and beauty of large, modern icebreakers and survey ships. This UGears wooden puzzle for adults and children lets you discover the complexity and mystery of mechanics, while fully enjoying the experience of ship building. The research vessel is a realistic miniature of a real ship. Your new ship has all you need to implement proper research: a bathyscaphe for deep-sea exploration, a small motorboat and lifeboat, a deployable ramp, and a hatch that opens along with more interesting elements you would find in real- life vessels. The model is equipped with a swing jib crane to manage cargo and to hoist the bathyscaphe. Use the crane to pull the bathyscaphe out of the depths and secure it on its special extended platform. YouÃll enjoy this UGears boat model kit because: ITÃS A THRILLING EXPERIENCE: It takes some patience and time to put together this mechanical puzzle. All parts are made of high-quality, laser-cut plywood. IT MOVES: The energy driving the 3D model is produced by a rubber band motor and managed by a pendulum. A clever gear arrangement imitates the sound of a diesel engine and propels the vessel at a smooth, steady pace. This mechanical model has three movement modes: forward, turning, and automatic. IT BRINGS JOY: Both shipbuilding hobbyists and lovers of original dÃ©cor will be astonished by the NEW line of UGears wooden model ship kits.
