Fabulous, funky toy boats are a variation on the original Schuco “Elektro-Cabino 5511” series. All plastic, with an electric motor. You need a set of penlite batteries, and you’re all set. Fill the tub, set the rudder, and watch out! They run just great. A little vaseline on the gears and shaft (dry ‘em out after use) and they’ll run a long time. Each is about 8 ½” long. Assorted Colors.
