Aboard the drifting boat, John decides that it is safer to hoist the sails and go farther out to sea rather than stay near the shore among the sandbanks and shoals of the estuary, with the risk of being wrecked in the fog. A strengthening wind blows away the fog after a couple of hours, only for blinding rain to replace it.
Lift on a sail (L), acting as an airfoil, occurs in a direction perpendicular to the incident airstream (the apparent wind velocity, V A, 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.
Points of sail: the shaded area is the "no-sail" zone. Beating to windward on short (P1), medium (P2), and long (P3) tacks, each with a progressively wider corridor over the water. Sails are limited in how close to the direction of the wind they can power a sailing craft. The area towards the wind defining those limits is called the "no-sail zone".
A sail is basically an airfoil. When full it is curved in such a way as to create a sideways "lift," or force perpendicular to its surface, one component of which is actually against the general direction of the wind. A sailing vessel can thus sail "into the wind." A keel prevents the ship from "slipping," or sliding sideways along the wind ...
The physics of sailing arises from a balance of forces between the wind powering the sailing craft as it passes over its sails and the resistance by the sailing craft against being blown off course, which is provided in the water by the keel, rudder, underwater foils and other elements of the underbody of a sailboat, on ice by the runners of an ...
Sailing into the wind is a sailing expression that refers to a sail boat's ability to move forward despite being headed into (or very nearly into) the wind. A sailboat cannot make headway by sailing directly into the wind ( see "Discussion," below); the point of sail into the wind is called " close hauled ".
After leaving, Leike said on X that the team had been "sailing against the wind." "OpenAI must become a safety-first AGI company," Leike wrote on X, adding that building generative AI is "an ...
For many sailing craft 45° on either side of the wind is a no-go zone, where a sail is unable to mobilize power from the wind. Sailing on a course as close to the wind as possible—approximately 45°—is termed beating, a point of sail when the sails are close-hauled. At 90° off the wind, a craft is on a beam reach.
