Kyōtei

A Kyōtei race is conducted on man-made lakes with a 600-meter oval boat course.

Once competitors receive the signal to pit-out of the docks, they will maneuver their boats in an effort to secure a starting position while a large clock situated at the start/finish line begins a one-minute countdown.

Once a race begins, boats fight for the best position entering the first turn marker.

During the practice, a straight run of 150 meters is timed for each boat and announced to the public.

Engines are used for only one year, after which they are rebuilt and sold for amateur and professional OSY-400 and C Stock Hydro races.

Performance over the time frame will determine of the competitor is promoted or relegated, or retain their rank.

SG races are held around eight times a year and are only open to the highest A1 kyōtei competitors.
