IT is a:
A-R-S "Cup Yacht" 508 Sailboat, 20" long Cup Yacht is a model of a 12-meter class racing yacht. Like the Australia II, Cup Yacht has a hydrodynamic winged keel for stability and speed. Assembly is fast because all the parts are prebuilt; you just assemble the boat like a plastic car kit. You may want to display it in your living room. The rigging and deck hardware are beautiful. But, It's a fast sailer with both main and jib sail controls. The glossy hull and keel is one piece molded of strong ABS resin. The aluminum mast is strong, and is removable for transporting. Cup Yacht requires a 2 channel radio. Use a regular airplane servo for sail control of both sails. Scale: 1:38, Length: 20", Beam: 4.6", Height: 31.4", weight: 2lbs., Sail area: 163 square in.
It is not now in production but was popular as a yacht that would fit in the back of the car and sailed very well for it's size but preferred light winds.
Happy sailing.
