Hydroplane racing (also known as hydro racing) is a sport involving racing hydroplanes on lakes and rivers. It is a popular spectator sport in several countries.

Racing circuits[edit]

International Professional Outboard Hydroplane Racing[edit]

The Union Internationale Motonautique (or "UIM", headquartered in Europe) sanctions many different hydroplane categories of hydroplane powerboat racing. International UIM F-125, F-250, F-350 and F-500 Circuit powerboat races are very popular in Europe, Asia, and the United States. UIM's O-series hydroplane Formula Circuit racing events are some of the most prestigious Professional Racing Outboard (PRO) hydroplane events in the world. National powerboat racing teams compete for national and international titles in these hydroplane racing circuits. The American Power Boat Association (APBA) sanction similar PRO class national title events in the United States. Professional F-series World Cup Title powerboat races are held at Europe, United States, and western Asia race site locations every year. Equivalent APBA PRO classes are 125ccH (UIM O-125), 175ccH (UIM O-175), 250ccH (UIM O-250), 350ccH (UIM O-350), 500ccH (UIM O-500), 750ccH (APBA only), and 1000ccH classes. PRO classes using 500cc and larger displacement racing motors must be equipped with an enclosed re-enforced capsule, a certified racing harness restraint system, and a self-contained oxygen system for the driver. The faster classes of PRO hydroplanes (with straightaway speeds from around 75 to 120 miles per hour) use 2-cycle outboard motors running highly filtered methanol race fuel mixed with a pure castor or synthetic castor-based lubricating oil. All methanol-fueled and gas-fueled PRO racing outboard motors are direct drive and equipped with high performance, motorcycle racing style magneto ignition and carburetor systems. 125cc through 1000cc PRO series hydroplanes are not entry level classes in outboard powerboat racing. Investment costs are moderately high compared to similar APBA stock and modified outboard racing classes. K-PRO (an APBA entry class) is the only PRO hydroplane class running modified, recreational outboard motors; all other PRO hydroplane classes use 2-cycle outboard motors designed and manufactured specifically for PRO circuit racing purposes. Entry level classes for the PRO series classes are gasoline-fueled K-PRO (APBA sanctions only) and OSY-400 (sanctioned by both UIM and APBA.) International UIM teams have a formal crew that usually consists of family members, motor mechanic, hull builder sponsor, and owner/driver team in order to be successful at racing international F-125 through F-500 Circuit hydroplanes. Some hydroplane hull builders sponsor more than one team in a formula series circuit. PRO outboard hydroplane hulls are constructed with lightweight wood, composite, and hybrid (wood/composite/aluminum) materials. Outboard Performance Craft hydroplanes (sometimes called "tunnel boats") are a different racing series of UIM and APBA outboard powerboat classes. Limited hydroplane racing classes are inboard-powered boats that use high performance gasoline fuel.

Grand Prix Hydroplane Racing[edit]

Grand Prix (GP) is a class of boats featuring supercharged big-block engines producing as much as 1,500 horsepower. The 23–26 foot craft are fast routinely attain speeds in excess of 170 miles-per-hour(273.5 km/h)in the straights. This class of boat races in the United States, Canada, Australia and New Zealand.

Unlimited Hydroplane Racing[edit]

Main article: H1 Unlimited

Although bit of a misnomer as the boats aren't without limits, unlimited hydroplanes have much fewer restrictions than with limited hydroplane racing. These 30 foot, 6,800 lbs boats run primarily with a T-55 L7 turbine engine (used during the Vietnam era in the Chinook helicopter) capable of up to 3000 horsepower with current restrictions. The T-55 L7 powerplant creates high speed rotation which is transferred through a gearbox at around 50% reduction of turbine to propeller RPM. Unlimited hydroplanes are capable of speeds of 200+ MPH on the straight-a-ways and qualifying average lap speeds range from 130-165 MPH. Modern hulls are constructed of composite materials such as honeycomb aluminum, fiberglass, laminated resin and carbon fiber. Many of the restored, fully operable unlimited hydroplanes at the Hydroplane & Raceboat Museum in Kent, Washington (such as the Miss Wahoo and Miss Thriftway vintage restorations) still use piston power aircraft engines. The primary racing circuit for unlimited racing is the H1 Unlimited, whose season runs from mid-February through September, consisting of eight races. H1 Unlimited races occur throughout the United States, and the Middle East.

Stock & Modified Outboard Racing[edit]

Stock Outboard Racing uses both hydroplane and runabout or monoplane hulls with racing engines that use a service outboard powerhead and a racing lower unit with a direct drive (i.e. start in gear). Racing in this form ranges from classes designated as follows: A Class, B Class, C Class and D Class. There is also a Junior or "J" Class for kids between the ages of 9 and 16 years of age. The engine sizes range from 9.9 horsepower (7.4 kW) to 50 horsepower (37 kW) with speeds from 30 miles per hour (48 km/h) to 90 miles per hour (140 km/h). In the C Stock Class, the Yamato Motor Company engines used in kyōtei, parimutuel betting in Japan, are reconditioned, shipped to the United States and used for racing in these classes.

Modified Outboard Hydroplane Racing classes are powered by modified stock outboard class motors. Motor modifications are limited to strict motor specifications and equipment alterations defined and published in APBA category rule books for these outboard hydroplane racing classes. Both stock and modified outboard classes run on a circular or triangular race course using a 3-minute "milling warm-up" period before a "flying" clock start. Heats usually consist of three laps around a closed race course. Drivers are disqualified if they cross the starting line before the official heat's clock start time (called "jumping the gun".) Just like the Stock & PRO hydroplane racing categories of APBA, the Modified hydroplane racing category membership has its own governing powerboat racing committee and rules book.

Hydroplane Racing Safety Improvements[edit]

In the early days of hydroplane racing, accidents, and even the deaths of drivers, were considered somewhat routine. As top speeds increased, more attention was paid to driver safety, much like with NASCAR auto racing and GP Circuit motorcycle racing driver safety programs today. Governing UIM and APBA powerboat racing organizations have promoted and specified many modern technology safety measures and rules for international hydroplane racing. Modern safety technology applications like composite fiber re-enforced Kevlar cockpits, capsule-enclosed driver modules with improved safety harness systems (in PRO, OPC, and limited/unlimited inboard hydroplanes), flip-over incident escape hatches & engine shut-off features, oxygen system & aircraft-quality windscreen canopies for capsule hulls, and advanced ballistic impact-resistant suits with improved helmet/neck brace wear—all of these improvements making the boats and specialized personal protection gear safer for the present-day driver. The HANS device, developed by sportscar racer Jim Downing, has become mandatory in many classes, and future advanced head and spine protection applications (driver upper body control & stabilization during high G-force events) are being tested in future hydroplane capsule designs.
