Dinghy sailing is the activity of sailing small boats by using five essential controls:
the sails
the foils (i.e. the daggerboard or centreboard and rudder and sometimes lifting foils as found on the Moth)
the trim (forward/rear angle of the boat in the water)
side-to-side balance of the dinghy by hiking or movement of the crew, particularly in windy weather ("move fast or swim")
the choice of route (in terms of existing and anticipated wind shifts, possible obstacles, other water traffic, currents, tides etc.)
When racing, the above skills need to be refined and additional skills and techniques learned, such as the application of the "racing rules of sailing", boat handling skills when starting and when rounding marks, and knowledge of tactics and strategy. Racing tactics include positioning the boat at different angles. To improve speed when racing, sailors should position themselves at the windward direction (closest to the direction of the wind) in order to get "clean air".
The RYA, the regulating authority for sail training in the UK, states that, "With a reliance on nature and the elements, sailing ... is about adventure, exploration, teamwork and fun."
There has always been a need for small tender boats for transporting goods and personnel to and from anchored sailing ships. Together with other smaller work craft such as fishing and light cargo, small inshore craft have always been in evidence. Charles II of England had a private sailing boat presented to him when he returned from exile to England in the 17th century, and he sailed for recreation and competition.
In 1887 Thomas Middleton, a Dublin solicitor, considered that yacht racing was becoming an excessively expensive activity, with boats becoming eclipsed by better designs each year. He proposed the 'One Model' principle. He wanted yacht racing to be an exercise of skill with all boats being built to the same design. He assembled a group of potential owners who agreed to call the boat 'The Water Wag'.

A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture. List of sailing boat types Although sailboat terminology has varied across history, many terms have specific meanings in the context of modern yachting. A great number of sailboat-types may be distinguished by size, hull configuration, keel type, purpose, number and configuration of masts, and sail plan.
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the water (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ice (iceboat) or on land (land yacht) over a chosen course, which is often part of a larger plan of navigation. From prehistory until the second half of the 19th century, sailing craft were the primary means of maritime trade and transportation; exploration across the seas and oceans was reliant on sail for anything other than the shortest distances.
In this work, various aspects concerning the numerical simulation of a sailing boat are investigated. The attention is focused on simulation of the free-surface, the fluid-structure interaction (FSI) between wind and sails, and the dynamics of the whole bo ...
The numerical simulation of free-surface flows around sailing boats is a complex topic that addresses multiple mathematical tasks: the correct study of the flow field around a rigid hull, the numerical simulation of the hull dynamics, the deformation of th ...
The topic of this thesis is the study of several stochastic control problems motivated by sailing races. The goal is to minimize the travel time between two locations, by selecting the fastest route in face of randomly changing weather conditions, such as ...
