Ski racing Water ski racing consists of 1 or 2 skiers per boat who race around a set course behind boats set up for this type of event. It can occur in a 'circle' or lap format type racing or on river courses offering longer distances and higher speeds. Races can be timed events such as 20 minute races and up to 1 hour or on courses where race distance can be over 100 km in length. Speeds vary by classes but can reach up to 200 km/h. Boats can be inboards or outboards and are generally between 19 and 21 feet in length. Outboards are commonly 300HP and Inboards around 1,300HP (majority are turbocharged). Current format world championship racing involves men's and women's open (unrestricted), and men's and women formula 2 (limited to single rig, 300 hp outboards, as well as junior classes for under 17's.
