Sailing is a sport in which the mental strength and physical ability of the sailor are pitted against the forces of nature.
Rob Walker, BBC Sport
"These athletes are not just contending with the handling of their boat, they are contending with the elements that can change vastly on a day-to-day basis. It is one of the most challenging ways you can win an Olympic medal. Everywhere you look across the classes, male and female, Team GB have reason to believe many of their sailors could come back with medals. Ben Ainslie has been winning medals since he was 19 and can judge the next move, the next gust of wind, the next wave, better than anyone. Hannah Mills and Saskia Clark in the 470 have an incredible chemistry together. In the women's Laser, Dutchwoman Marit Bouwmeester could emerge as one of the icons of the Olympic regatta."
Ten events will be contested at this London 2012, six for men and four for women in vessels from dinghies and keelboats to windsurfing boards. There are three disciplines - match racing, fleet racing and windsurfing.
With 24 gold medals since the 1900 Games, Great Britain is the most successful sailing nation in the world and Team GB are strong favourites to top the medal table for the fourth Games in a row.
Hopes are firmly pinned on one of Britain's greatest ever Olympians, Ben Ainslie, who is chasing his fourth consecutive gold medal.
The fact that the sailing events will take place off the coast of Weymouth and Portland in Dorset, a venue well known to the host nation's sailors, should only boost their chances.
Why is it good for you?
The power required to manoeuvre the boat around the course ensures sailing builds strength and endurance in the arms, shoulders and chest muscles.
While sailing does improve power, it also aids the ability to think strategically and tactically due to the challenge of having to constantly react to changing conditions.
This means it is a sport in which people of all ages can compete against each other on equal terms. In the 1964 Olympics in Tokyo, Sir William Northam won gold in the 5.5m class when aged 59.
Spending time on the sea has been found to help people relax as the salt in the sea air helps balance the levels of serotonin, a chemical produced by the body that is associated with mood and stress.
Sailing is one of the best ways to get away from it all, leaving the daily grind of a hectic work life behind while enjoying the excitement of being on the water.

The rules at London 2012
Crew sizes vary from one to three, with Laser, Laser Radial, Finn and RS-X classes featuring one sailor; the 49er, 470, and Star featuring two and the women's match racing three. The boats compete in 10 fleet races (15 for the 49er), with each regatta lasting a series of days.
Great Olympic moment

Points in each race are given according to position. The winner of each race gets one point, the second-placed finisher gets two etc and then, after being allowed to discard their worst result, the top 10 boats advance to the medal race where points are doubled.
Following the medal race, the individual or crew with the lowest points total is the winner.
In match racing, the first boat across the line wins the match. Teams compete against each other in a series of round-robin matches, with the top teams progressing to the final knockout stages.
Sailors in each category race equally-matched boats around a course of buoys, with the first to cross the finishing line winning that race. Different classes have different course layouts.
Infringements include observing the correct right of way and obstruction rules while on the water, false starting, or touching a mark. Penalties include having to take an extra one or two turns (turning your boat 360 or 720 degrees through the wind), or receiving a scoring penalty.
Competitors can protest to officials if they believe a rule infringement has been made.

International yacht racing began in 1851 with the America's Cup and sailing was part of the first Olympics in 1896, but heavy winds saw the programme cancelled.
The breeze had died off by the time the Olympic flame arrived in Paris four years later and the sport has been contested at every Games since.
Women have always been allowed to compete in Olympic sailing with men, but in 1988 separate sailing events were introduced exclusively for women.
The classes of boats have changed over time as yacht design and technology has evolved. Match Racing for women - a head-to-head contest between teams on two identical boats - will make its debut in 2012.
