U.S. Patent #:	5,194,024
Inventor :	Wilton Fukumi Shiraki

As attorney for the inventor of the innovative Propeller Driven Surfboard we are currently seeking manufacturing companies to license, purchase patent rights or enter into a royalty agreement for this timely invention.

At the 20th Annual International Human Powered Speed Championships held in Eureka, California in August 1994, the Hawaiian Cycleboard tm completed the 100 meter sprints in 33.6 seconds and took the Gold Medals in the 200 Meter Slalom and 1,000 meters Criterion water events. These accomplishments are especially noteworthy to the recreational industry as the rider was a 14 year old boy from Illinois with no previous watercraft experience. The two Gold Medals were taken during his second and third trials on the vehicle. His first attempt at riding the Hawaiian Cycleboard tm resulted in the 33.6 second time in the 100 meters.

As I believe the average tourist is looking for maximum fun with minimum hassle, the Hawaiian Cycleboard tm will prove to be the water vehicle of choice wherever they are available. Photographs and a videotape of this award winner are available upon request at no charge from the inventor at the address listed on the enclosed patent.

Objects of the present invention:

• to provide a propeller driven surfboard that is operated by pedal power from the legs of a person sitting on a seat on the surfboard
  
  
• to provide a propeller driven surfboard that is steered by the person sitting on the seat on the surfboard controlling a rudder at the stern
