420 coach kit includes four boats, each with sails (main, jib, spinnaker). All the boats have a different colour so they can be easily distinguished. There are also six buoys (2 yellow, 4 orange). Boats and buoys come with magnets so they can be attached to a white board or other metallic surface. All the parts come in a storage box. Every item, including the box, is 3D- printed.
