Lawrence, and eventually began to explore the Pacific Northwest and the Western Arctic.
Sailing has contributed to many great explorations in the world.
Conventional sailing craft cannot derive power from sails on a point of sail that is too close into the wind.

Recreational sailing or yachting can be divided into racing and cruising.
Cruising can include extended offshore and ocean-crossing trips, coastal sailing within sight of land, and daysailing.
Right-hand boat: Up wind (close-hauled) with attached airflow like a wing—predominant lift component both propels the boat and contributes to heel.
Lift on a sail, acting as an airfoil, occurs in a direction perpendicular to the incident airstream (the apparent wind velocity for the head sail) and is a result of pressure differences between the windward and leeward surfaces and depends on angle of attack, sail shape, air density, and speed of the apparent wind.
The lift force results from the average pressure on the windward surface of the sail being higher than the average pressure on the leeward side.
These pressure differences arise in conjunction with the curved air flow.
Until the mid of the 19th century, sailing ships were the primary means for marine commerce, this period is known as Age of Sail.
Throughout history sailing has been instrumental in the development of civilization, affording humanity greater mobility than travel over land, whether for trade, transport or warfare, and the capacity for fishing.
The forces transmitted via the sails are resisted by forces from the hull, keel, and rudder of a sailing craft, by forces from skate runners of an iceboat, or by forces from wheels of a land sailing craft to allow steering the course.
In the 21st century, most sailing represents a form of recreation or sport.
The earliest representation of a ship under sail appears on a painted disc found in Kuwait dating between 50 BCE.
