The Coypu is a class of small sailing dinghy. It is a highly stable boat, suitable for beginners, and is normally sailed by two people, although three can be accommodated comfortably.
Dinghy sailing is the activity of sailing small boats by using five essential controls:
The variants in the design of the coypu depend on the builder. The hull is normally glass-reinforced plastic construction, with buoyancy tanks on front, sides, and rear. The centreboard is metal, and the rudder is removable, either fixed (i.e. does not have a downhaul) or with a moveable blade.
A centreboard or centerboard (US) is a retractable keel which pivots out of a slot in the hull of a sailboat, known as a centreboard trunk (UK) or centerboard case (US). The retractability allows the centreboard to be raised to operate in shallow waters, to move the centre of lateral resistance, to reduce drag when the full area of the centreboard is not needed, or when removing the boat from the water, as when trailering. A centreboard which consists of just a pivoting metal plate is called a centerplate. A daggerboard is similar but slides vertically rather than pivoting.
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other conveyance that moves through a fluid medium. On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft) or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics.
The downhaul is a line which is part of the rigging on a sailboat; it applies downward force on a spar or sail. The most common downhaul on a modern sailboat is attached to the spinnaker pole, though this may be referred to as the foreguy in some rigging nomenclature. The term is also commonly applied to the cunningham on the mainsail.
Most Coypu mainsails are normally raised by feeding the luff into the track on the mast, although some variants have gunter rig sails. The mainsheet is fixed to the stern of the boat. A jib is used for normal use and only one size is available.
A mainsail is a sail rigged on the main mast of a sailing vessel.
In sailing, a gunter is used for two main configurations of rig:
The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite of the bow, the foremost part of a ship. Originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a white navigation light at night.
The boat is heavy in comparison with other dinghies, so traditionally they have proved popular at training centres where removing the boat from the water on a regular basis is not necessary. However, the design provides a stable boat in all weather, which is ideal for beginners, especially juniors.
Also, a "sea scout" version of the coypu dinghy is available. [1]
The Coypu is a rather old design of boat. It is possible to get replacement spares. The design of the boat meant that small boatyards and centres could build their own fleet easily, with assistance from a mould. The design also meant that they were easy to repair, and as a result, they have long service lives.
Previous centres known to have built Coypu hulls include:
Bury Lake Young Mariners has been operating since 1983 at Bury Lake in Rickmansworth Aquadrome, Hertfordshire, England. The charity has more than 100 boats and each year enables around 7,500 mostly young people to go sailing.
Rickmansworth is a small town in southwest Hertfordshire, England, approximately 17 miles (27 km) northwest of central London and inside the perimeter of the M25 motorway. The town is mainly to the north of the Grand Union Canal and the River Colne. The nearest large town is Watford, approximately 5 miles (8.0 km) to the east. Rickmansworth is the administrative seat of the Three Rivers District Council. The confluence of the Chess and the Gade with the Colne in Rickmansworth inspired the district's name. The enlarged Colne flows south to form a major tributary of the River Thames. The town is served by the Metropolitan line of the London Underground and Chiltern Railways from London Marylebone to Aylesbury.
Hertfordshire is one of the home counties in England. It is bordered by Bedfordshire and Cambridgeshire to the north, Essex to the east, Greater London to the south, and Buckinghamshire to the west. For government statistical purposes, it is placed in the East of England region.
Yachting refers to the use of recreational boats and ships called yachts for sporting purposes. Yachts are distinguished from working ships mainly by their leisure purpose.
The Mirror is a popular sailing dinghy with more than 70,000 built.
Boat building is the design and construction of boats and their systems. This includes at a minimum a hull, with propulsion, mechanical, navigation, safety and other systems as a craft requires.
The International Laser Class sailboat, also called Laser Standard and the Laser One is a popular one-design class of small sailing dinghy. According to the Laser Class Rules the boat may be sailed by either one or two people, though it is rarely sailed by two. The design, by Bruce Kirby, emphasizes simplicity and performance. The dinghy is manufactured by independent companies in different parts of the world, including LaserPerformance, Performance Sailcraft Australia (Oceania) and Performance Sailcraft Japan.
The Optimist, also known as the 'bathtub', is a small, single-handed sailing dinghy intended for use by children up to the age of 15. Contemporary boats are usually made of fibreglass, although wooden boats are still built.
Otter is a classification referring to a particular design for a two-man sailing dinghy with a glass fibre hull. Its rig consists of a main, a jib and an optional symmetric spinnaker. The hull dimensions are 11 ft 11 in length and 4 ft 10 in beam. The boat has a draft of 3 ft 6 in with the centreboard down. The sail area is 75 sq. ft. The class symbol is a stylised glass bubble; due to the original lightweight "cigar box cedar" construction of the prototypes, the name 'Bubble' was first used for the boat. John Baker obtained the plans for an expanded version of the boat in G.R.P. and hence renamed the boat 'Glass Bubble'. After being put into production by Baker, the name 'Otter' was adopted; coming from the river of the same name in East Devon, close to where the boat was manufactured.
The P-Class is a type of small single sail dinghy, popular as a training boat for young people in New Zealand. This class is famous for being the sailing trainer vessel for many new entrants into the sport, and virtually every famous New Zealand yachtsman, including Sir Peter Blake and Russell Coutts, learnt to sail in one. The P-Class was for many years the most common sailing boat in New Zealand.
The Adventuress sailing dinghy class was designed by Ian Proctor and built by Anglo Marine of Essex. It is no longer in production.
The Bell Woodworking Seagull and Seamew are both small sloop-rigged marine ply sailing boats of the Trailer yacht type designed by Ian Proctor, who was also responsible for the design of many small sailing dinghies in seven different classes including the extremely popular Topper, and Wanderer.
The Bermuda Fitted Dinghy is a type of racing-dedicated sail boat used for competitions between the yacht clubs of Bermuda. Although the class has only existed for about 130 years, the boats are a continuance of a tradition of boat and ship design in Bermuda that stretches back to the earliest decades of the 17th century.
The Astus 14.1 is a 14 ft (4.18m) trimaran dinghy aimed at recreational sailing and racing. The trimaran design is unusual for a boat of this size but is said to combine the features of other types of design: pointing ability of a monohull dinghy, reaching ability of a catamaran, and planing ability of a skiff. The stability provided by the floats makes the boat accessible to beginners and single-handed racers.
The Pelican is a pram dinghy, peculiar to Perth, Western Australia
The Norfolk Punt is a type of yacht, derived from the flat-bottomed gun punts that roamed the Broadland waters in the mid-to-late 19th century. However, at the turn of the 20th century, in order to get to and from the hunting grounds more efficiently, the punters developed their highly unstable craft to carry a basic mast and sail for travelling with the wind. It is from these humble beginnings that one of the country’s most exciting and powerful racing dinghy classes was born.
The Naples Sabot is an 8-foot (2.4 m) sailing dinghy. The Naples Sabot was designed by Roy McCullough and R.A. Violette and the first two were built in Violette's garage during WW II, although official designs were not made available until 1946. The Naples Sabot is based on the Balboa Dinghy and on Charles MacGregor's Sabot as published in Rudder magazine, April 1939. It takes its name from Naples in Long Beach, California, where it was developed.
The RS Tera is a one-man monohull dinghy in the RS Sailing range of sailing boats. It is recognised by the International Sailing Federation (ISAF) as an international class, and is a popular boat for beginners and for children to race.
