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 Laser is one of the most popular single-handed dinghies in the world. As of 2018, there are more than 215,000 boats worldwide. A commonly cited reason for its popularity is that it is robust and simple to rig and sail in addition to its durability; it's also very fast. The Laser also provides very competitive racing due to the very tight class association controls which eliminate differences in hull, sails and equipment.
The Laser Radial is a popular one-design class of small sailing dinghy, originally built by Laser Performance. It is a singlehanded boat, meaning that it is sailed by one person. The Laser Radial is a variant of the Laser Standard, with shorter mast and reduced sail area, allowing light sailors to sail in heavy winds. The International Class is recognised by the International Sailing Federation.
A smaller sail plan for the Laser was developed about a decade after the Laser Radial. The sail area was reduced by 35% from the Standard (from 7 m² to 4,7 m²) with a shorter, pre-bent bottom mast section, allowing even lighter sailors to sail it. The same formula as the Radial is kept. The hull is the same as the Standard and Radial. Optimal weight for this rig is 110–145 lb (50–65 kg), thus becoming an ideal boat for young sailors moving from the Optimist/RS Tera who are still too light for a normal Laser. The Laser 4.7 rig has a UK Portsmouth Yardstick number of 1200
The 470 (Four-Seventy) is a double-handed monohull planing dinghy with a centreboard, Bermuda rig, and centre sheeting. Equipped with a spinnaker, trapeze and a large sail-area-to-weight ratio, it is designed to plane easily, and good teamwork necessary to sail it well. The name comes from the overall length of the boat in centimetres (i.e., the boat is 4.70 metres long).
The 470 is a popular class with both individuals and sailing schools, offering a good introduction to high-performance boats without being excessively difficult to handle, but it is not a boat designed for beginners. Its smaller sister, the 420, is a stepping stone to the 470.
The International 420 Dinghy is a dinghy with centreboard. The name refers to the boat length in centimeters, being 4.2 meters. The hull is fiberglass with internal buoyancy tanks. The 420 has a bermuda rig and an optional spinnaker and trapeze. It has a large sail-area-to-weight ratio, and is designed to plane easily. It can be rigged to be sailed single-handed or double-handed. The 420 is an International class recognized by the International Sailing Federation.
The Optimist, also known as the ‘opti’, 'oppie' or '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.
It is one of the most popular sailing dinghies in the world, with over 150,000 boats officially registered with the class and many more built but never registered.
Windsurfing is a surface water sport that combines elements of surfing and sailing. It consists of a board usually 2 to 2.5 metres (6 ft 7 in to 8 ft 2 in) long, with displacements typically between 45 and 150 litres (9.9 and 33.0 imp gal; 12 and 40 US gal), powered by wind on a sail. The rig is connected to the board by a free-rotating universal joint and consists of a mast, boom and sail. On “short” boards The sail area generally ranges from 1.5 to 12 square metres (16 to 129 sq ft) depending on the conditions, the skill of the sailor, the type of windsurfing being undertaken and the weight of the person windsurfing. On long boards, upon which the sport was first popularized -sail areas and board lengths are typically larger and the athleticism required is much less.
Kiteboarding is an action sport combining aspects of wakeboarding, snowboarding, windsurfing, surfing, paragliding, skateboarding and sailing into one extreme sport. A kiteboarder harnesses the power of the wind with a large controllable power kite to be propelled across the water, land, or snow.
Compared to the other sailing sports, kiteboarding is both among the less expensive (including equipment) and the more convenient. It is also unique in that it harvests the wind energy from a much larger atmosphere volume, comparing to sail size.
Keel Boat: The keel is basically a flat blade sticking down into the water from a sailboat's bottom. It has two functions: it prevents the boat from being blown sideways by the wind, and it holds the ballast that keeps the boat right-side up.
The keel is basically a flat blade sticking down into the water from a sailboat’s bottom. It has two functions: it prevents the boat from being blown sideways by the wind, and it holds the ballast that keeps the boat right-side up. That’s all you really need to know about the keel to enjoy sailing—OK, you have to know how deep it is so you don’t run aground—but in fact the keel is a pretty interesting structure.
Keels come in many styles. Traditional boats have graceful keels built into the shape of the hull; the ballast is either bolted to the bottom of the keel or placed inside it. The keel is built of whatever the boat is built of—usually fiberglass, aluminum or wood—and the ballast is lead. This is a sturdy, time-proven design, especially good for a cruising boat, which might run aground on an uncharted reef or require hauling out in a remote part of the world.
A radio-controlled boat is a boat controlled remotely with radio control equipment.
The 49er and 49er FX is a two-handed skiff-type high-performance sailing dinghy. The two crew work on different roles with the helmmaking many tactical decisions, as well as steering, and the crew doing most of the sail control. Both of the crew are equipped with their own trapeze and sailing is done while cantilevered over the water to the fullest extent to balance against the sails.
The 49er was designed by Julian Bethwaite (the son of Frank Bethwaite) and developed by a consortium consisting of Bethwaites, Performance Sailcraft Japan, Peter Johnston, and Ovington boats. The boat has been an Olympic class since it was selected by the International Sailing Federation to be the men's high performance double handed dinghy Sydney Summer Games of 2000. Its derivative featuring a re-designed rig, the 49er FX, was selected by World Sailing to be the women's high performance double-hander at the Rio Summer Olympics of 2016.
