Dinghy racing is the competitive sport of sailing dinghies. Dinghy racing has affected aspects of the modern dinghy, including hull design, sail materials and sailplan, and techniques such as planing and trapezing.
Dinghy racing comes under the auspices of the International Sailing Federation. Organisations such as the Royal Yachting Association, National School Sailing Association (UK) and Canadian Yachting Association (Canada) organise and regulate the sport at a national level. Sailing dinghies compete on an international, national, state, association, club and class basis, using the ISAF International Racing Rules of Sailing, which are revised every four years. There are several courses used, such as the Olympic triangle.
The International Association for Disabled Sailing (IFDS) is the body authorized by ISAF to be responsible for disabled sailing worldwide. IFDS works with yachting associations worldwide to run regional events all the way to the Paralympic Games, as well as adapt ISAF Racing Rules of Sailing to meet disability requirements. Many standard boats are suitable for people with disabilities which can be made more accessible by adaptations. More boats are being designed with disabled people in mind and used regularly around the world by people with disabilities.
Dinghys typically race around a windward-leeward race course. There is a start/finish "line", set up perpendicular to the wind, marked by a committee boat at one end, and a buoy on the other. At the end of five minutes, competitors are allowed to cross the line and begin to race to the next mark. The next mark is called the windward mark. The windward mark is placed directly upwind from the start/finish line. Competitors must round the mark going counter-clockwise. After rounding the windward mark, the fleet now heads towards the leeward mark. The leeward mark is positioned directly downwind from the windward mark, below the start/finish line. Sailors also round this mark counter-clockwise. After rounding, competitors head upwind to cross the finish line.
