Types of Sailing Competitions (Sailing Races)

In Sailing races, sailors compete against other boats for speed by using wind power received by their sails to generate propulsion without the use of engines, motors, or any other power source.
Olympic sailing competitions and other dinghy races are called one-design class, in which boats of the same type are used to decide the ranking according to the order of arrival. The series race format is the most common, with 2 to 5 races per regatta (one event), and often more than 10 races. For example, the boat that comes in first place gets 1 point, second place gets 2 points, and so on. The scores for all races are totaled and ranked from the lowest total score to first.
Sailboats come in a variety of sizes and shapes, and the number of people on board and their competitiveness will vary depending on their requirements. Therefore, while there are one-design class races, when boats of various sizes and types race against each other, as in the Yanmar Cup, the rating* is established and the rankings are determined by time modification multiplied by a handicap factor calculated from the rating. For example, if two boats finish in the same 30 minutes, boat A with a handicap of 0.9 and boat B with a handicap of 0.8 have different scores: boat A takes 27 minutes (30 x 0.9) and boat B takes 24 minutes (30 x 0.8); boat B with a shorter race time will be ranked higher.

*Rating: A rating for each boat used in sailing races between different boat types. From this, a coefficient is calculated as a handicap for each boat, and the finishing time is modified to ensure a fair race.


Cruiser (Keelboat)

  • A small sailboat with a ballast keel (a weight in the center of the bottom) and no engine is called a keelboat.
  • Boats equipped with engines and living quarters to run on the open sea are called cruisers or sailing cruisers.
  • Basically, the sailboat is sailed by a large group of 3 or more people, each in charge of a role. There are also races for one rider, single-handed and two riders, double-handed.
  • In addition to one-design class, handicap races in which different boat types compete using ratings are also popular.
