In boating, P-class could refer to either of:
A yacht is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a yacht, as opposed to a boat, such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities.
Yacht racing is a sailing sport involving sailing yachts and larger sailboats, as distinguished from dinghy racing, which involves open boats. It is composed of multiple yachts, in direct competition, racing around a course marked by buoys or other fixed navigational devices or racing longer distances across open water from point-to-point. It can involve a series of races with buoy racing or multiple legs when point-to-point racing.
The America's Cup, informally known as the Auld Mug, is a trophy awarded in the sport of sailing. It is the oldest international competition still operating in any sport. America's Cup match races are held between two sailing yachts: one from the yacht club that currently holds the trophy and the other from the yacht club that is challenging for the cup. Matches are held several years apart on dates agreed between the defender and the challenger. There is no fixed schedule, but the races have generally been held every three to four years. The most recent America's Cup match took place in March 2021.
Boat racing is a sport in which boats, or other types of watercraft, race on water. Boat racing powered by oars is recorded as having occurred in ancient Egypt, and it is likely that people have engaged in races involving boats and other water-borne craft for as long as such watercraft have existed.
Class 8 may refer to:
The International Americas Cup Class is a class of racing yacht that was developed for the America's Cup between 1992 and 2007. These yachts, while not identical, were all designed to the same formula to offer designers the freedom to experiment whilst keeping the boats sufficiently comparable to race in real time. The class was established for the 1992 America's Cup because of perceived shortcomings of the 12-metre class, which had been used in the America's Cup since 1958.
The 12 Metre class is a rating class for racing sailboats that are designed to the International rule. It enables fair competition between boats that rate in the class whilst retaining the freedom to experiment with the details of their designs. The designation "12 Metre" does not refer to any single measurement on the boat, and is not referencing the vessels overall length, rather, measures the sum of the components directed by the formula which governs design and construction parameters. Typically 12 Metre class boats range from 65 to 75 feet in length overall; they are most often sloop-rigged, with masts roughly 85 feet tall.
Land sailing, also known as sand yachting, land yachting or dirtboating, is the act of moving across land in a wheeled vehicle powered by wind through the use of a sail. The term comes from analogy with (water) sailing. Historically, land sailing was used as a mode of transportation or recreation. Since the 1950s, it has evolved primarily into a racing sport.
The Fireball is a British sailing dinghy that was designed by Peter Milne as a one-design racer and first built in 1962.
A J-Class yacht is a single-masted racing yacht built to the specifications of Nathanael Herreshoff's Universal Rule. The J-Class are considered the peak racers of the era when the Universal Rule determined eligibility in the America's Cup.
Performance Handicap Racing Fleet (PHRF) is a handicapping system used for yacht racing in North America. It allows dissimilar classes of sailboats to be raced against each other. The aim is to cancel out the inherent advantages and disadvantages of each class of boats, so that results reflect crew skill rather than equipment superiority.
The Dragon is a one-design keelboat designed by Norwegian Johan Anker in 1929. In 1948 the Dragon became an Olympic Class, a status it retained until the Munich Olympics in 1972. The Dragon's long keel and elegant metre-boat lines remain unchanged, but today Dragons are constructed using the latest technology to make the boat durable and easy to maintain. GRP construction was introduced in 1973 and the rigging has been regularly updated.
Christopher Stuart Dickson is a sailor from New Zealand. He was world youth champion three years in succession and later became world match race champion three times. He also skippered several yachts in America's Cup racing, and for New Zealand at the 2000 Summer Olympics, and in numerous other sailing competitions.
The International One Design is a class of sail boat developed in 1936 for yacht racing. It is a 33-foot open-cockpit day sailer used for day racing, rather than for overnight or ocean races. Popularised prior to the Second World War, the International One Design class is considered a classic one today.
The International Six Metre class is a class of classic racing yachts. Sixes are a construction class, meaning that the boats are not identical but are all designed to meet specific measurement formula, in this case International rule. At their heyday, Sixes were the most important international yacht racing class, and they are still raced around the world. "Six metre" in class name does not, somewhat confusingly, refer to length of the boat, but product of the formula; 6mR boats are, on average, 10–11 metres long.
A sailing yacht, is a leisure craft that uses sails as its primary means of propulsion. A yacht may be a sail or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies here to sailing vessels that have a cabin with amenities that accommodate overnight use. To be termed a "yacht", as opposed to a "boat", such a vessel is likely to be at least 33 feet (10 m) in length and have been judged to have good aesthetic qualities. Sailboats that do not accommodate overnight use or are smaller than 30 feet (9.1 m) are not universally called yachts. Sailing yachts in excess of 130 feet (40 m) are generally considered to be superyachts.
The Seaway 25 was designed by Doug Peterson of USA fame for Tom Stevenson in 1978 after Tom won the World half Ton championship in one of Doug's designs. The yacht was designed to sail well on the short sharp chop of Port Phillip Bay Melbourne Australia. Intended to rate as a quarter ton Trailer yacht under IOR and Junior Offshore Group racing both for Harbour and Inshore Yacht racing.
The sport of sailing involves a variety of competitive sailing formats that are sanctioned through various sailing federations and yacht clubs. Racing disciplines include matches within a fleet of sailing craft, between a pair thereof or among teams. Additionally, there are specialized competitions that include setting speed records. Racing formats include both closed courses and point-to-point contests; they may be in sheltered waters, coast-wise or on the open ocean. Most competitions are held within defined classes or ratings that either entail one type of sailing craft to ensure a contest primarily of skill or rating the sailing craft to create classifications or handicaps.
The Transpac 52 (TP52) is a class of yacht used for competitive 52 Super Series yacht racing, and the Audi MedCup previously, besides the world championship of the class. The class is recognised by the International Sailing Federation which entitles the class to hold an Official World Championships.
The America's Cup class may refer to any yacht-building rule or any group of racing yachts that were built for the America's Cup sailing competition, including:
