The energy that drives a sailboat is harnessed by manipulating the relative movement of wind and water speed: if there is no difference in movement, such as on a calm day or when the wind and water current are moving in the same direction at the same speed, there is no energy to be extracted and the sailboat will not be able to do anything but drift.Where there is a difference in motion, then there is energy to be extracted at the interface.

Lawrence, and eventually began to explore the Pacific Northwest and the Western Arctic.

A course defined with respect to the true wind direction is called a point of sail.

Conventional sailing craft cannot derive power from sails on a point of sail that is too close into the wind.

The sailboat does this by placing the sail(s) in the air and the hull(s) in the water.

A sailing vessel is not maneuverable due to sails alone—the forces caused by the wind on the sails would cause the vessel to rotate and travel sideways instead of moving forward.

Sails are airfoils that work by using an airflow set up by the wind and the motion of the boat.

The wind that a boat experiences is the combination of the true wind (i.e.Advances in sailing technology from the Middle Ages onward enabled Arab, Chinese, Indian and European explorers to make longer voyages into regions with extreme weather and climatic conditions.There were improvements in sails, masts and rigging; improvements in marine navigation including the cross tree and charts, of both the sea and constellations, allowed more certainty in sea travel.On a given point of sail, the sailor adjusts the alignment of each sail with respect to the apparent wind direction (as perceived on the craft) to mobilize the power of the wind.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.Sea poems, too, often tend towards allegory and are naturally suited to elegy, as concerned with the metaphorical passage from this world to the next as with any actual voyage across the earth’s oceans.
