To steer, a steerer will put the blade of the oar into the water and either push the handle away from him/her, or pull it toward him/her. Doing so will turn the boat right or left, respectively. A steerer can also use the steering oar to adjust the position of the boat by cranking. When a steerer cranks the steering oar, the stern of the boat moves either to the left or right, spinning the boat. This is typically executed to turn the boat around at practice or to ensure a boat is lined up straight and pointing directly down a racecourse. A steerer uses calls to direct the paddlers. The steerer may call "paddles up" to prepare to paddle and "take it away!" to commence paddling. The steerer may use other calls such as "hold the boat" for the paddlers to brake using their paddles or "let it ride" for them to lift their paddles out of the water. Modern dragon boat racing is organized at the international level by the International Dragon Boat Federation (IDBF), the world governing body for the sport. The IDBF is a member of the Global Association of International Sports Federations (Sportaccord) and is a founding federation of the AIMS Group (Alliance of Independent Recognized Members of Sport) within Sportaccord. AIMS is an IOC-Recognized Multi Sports Organization. The International Canoe Federation (ICF) also has a dragon boat program for those of its Member Canoe Federations with an interest in dragon boat. Both Sport and Festival racing are very competitive and many paddlers train year round, using paddling machines or pools in addition to on-water sessions. A festival race is typically a sprint event of several hundred meters, with 500 meters being the most common. Races measuring 200, 1000, and 2000 meters are also standard distances in international competition. Races measuring 2000 meters are normally held on a 500-meter course, requiring teams to do two loops. Teams start and end at the same end of the course, and complete three 180-degree turns. Other distances may also be used in local festivals, such as 100 or 250 meters, or another distance, depending on the size of the body of water. The established International Federation for dragon boat sport is the International Dragon Boat Federation (IDBF). In 2007, the IDBF was recognized as a member of SportAccord (the former "General Association of International Sports Federations", GAISF) which is part of the Olympic Movement, after SportAccord considered the historical and cultural backgrounds and identities of dragon boat sports.
