Question: The American Power Boat Association  sanctions a race in which category, which has a hull shape that allows the boat to be supported by planing forces?
Context: Donald Wayne Johnson (born December 15, 1949) is an American actor, producer, director, singer, and songwriter.  He played the role of James "Sonny" Crockett in the 1980s television series "Miami Vice" and had the eponymous lead role in the 1990s cop series "Nash Bridges".  Johnson is a Golden Globe–winning actor for his role in "Miami Vice", the American Power Boat Association's 1988 World Champion of the Offshore World Cup, and has received a star on the Hollywood Walk of Fame. Power boating describes activities performed in a motorized boat.  Generally, a power boat has a high power-to-weight ratio and a hull design that allows for easy planing, which allows for higher speed and improved handling.  Also, the shape of the actual boat is usually very streamlined, which minimizes air resistance and drag, therefore increasing speed.  Power boats are used in yachting, waterskiing and wakeboarding. The Tasar is a 14 ft fiberglass 2 person sailing dinghy with a mainsail and jib.  Designed by Frank Bethwaite of Sydney in 1975, the boat was technologically advanced for it time and continues to evolved.  Aimed at a husband-and-wife or parent-and-child crew hence no spinnaker, it is designed for a combined crew weight of around 140kg.  The hull weighs 68kg, and is of sandwich foam construction.  The hull has a fine angle at the bow to reduce wave impact drag with unusually clean and sharp chines aft to ensure very free planing and outstanding stability.  The foam cored hull is stiff and light and the advanced hull shape, together with an innovative rig which combines a rotating mast with a fully battened main sail, allows the Tasar to plane upwind with the crew normally hiked.  The wide beam and a cockpit designed for comfortable hiking make the Tasar easy, fun and very exciting to sail in winds up to 25 kn . Jim Hendrick (July 26, 1934 - June 15, 2017) was an American sports announcer.  Hendrick worked in sports broadcasting for over 50 years.  He gained fame for his work as a spokesman for Anheuser-Busch and his association with the American Power Boat Association. Jack Beebe was a hydroplane mechanic from Detroit, Michigan who drove the Miss Detroit hydroplane to the 1915 American Power Boat Association Gold Cup victory after replacing the original driver of the boat who became seasick. APBA Gold Cup is the premier hydroplane boat race in the United States, which is sanctioned by the American Power Boat Association and run as part of the H1 Unlimited season.  The race has been contested annually since 1904, and, up until 1990, rotated regularly between locations. The American Power Boat Association (APBA) is a New York membership owned corporation that was created in 1903 by an act of the New York legislature as a racing association for powerboats.  It is the United States sanctioning authority for the "Union Internationale Motonautique" (UIM), the world governing body for powerboat racing.  It is the sole governing body in the United States.  The APBA sanctions races in a number of different categories including the Unlimited Hydroplanes, Inboard, Outboard Performance Craft, Stock Outboard, Modified Outboard, Pro Outboard, Outboard Drag, Offshore and Special Events classes.  Each category comprises a number of different classes.  There are also many smaller regional clubs, including South Shore Outboard Association, located in New England. A hydroplane (or hydro, or "thunderboat") is a fast motorboat, where the hull shape is such that at speed, the weight of the boat is supported by planing forces, rather than simple buoyancy. Gale V was an unlimited hydroplane that raced in the 1950s.  The Gale V team won the National High Point Championship in 1954 and 1955 and won the American Power Boat Association Gold Cup in 1955 with Lee Schoenith driving.  The boat was retired after the 1955 season. H1 Unlimited is an American Unlimited Hydroplane racing league that is sanctioned by the American Power Boat Association (APBA).  Until 2009, the series was known as ABRA Unlimited Hydroplane, in turn renamed from APBA Unlimited Hydroplane in 2004.  The H1 Unlimited season typically runs from July through September, consisting of five races.
