Jet Joe - By WILLIAM D. JACKSON. A Sturdy, High-Speed Utility Racing Hydroplane. Put it in water and like a certain widely advertised soap, Jet Joe does everything. Not only does it do double duty as a utility and sports boat - hauling passengers, pulling water skiers and the like - but it also qualifies as a closed-course and marathon racer, fulfilling all requirements of the American Power Boat and National Outboard associations for sanctioned racing with stock, two-cylinder outboard motors of the Evinrude Big Twin type.
