Sail On! Sail On! Sail On! Sail On! "Sail On! Sail On!" is an alternate history short story by Philip José Farmer, first published in "Startling Stories" 1952. In an alternative 1492, Christopher Columbus sets out to find a shortened route to China and South-East Asia across the Atlantic, financed by Ferdinand V and Isabella I of Spain. However, in this timeline, the Earth "is" flat, though scientists and philosophers have doubts about its geological provenance, and an Angelo Angelli is mentioned as proving Aristotle's axiom that objects of different weights drop with different velocities (which Galileo Galilei disproved in our world).

Point of sail of sail. On conventional sail boats, the sails are set to create lift for those points of sail where it's possible to align the leading edge of the sail with the apparent wind. For a sailboat, point of sail significantly affects the lateral force to which the boat is subjected. The higher the boat points into the wind, the stronger the lateral force, which results in both increased leeway and heeling. Leeway, the effect of the boat moving sideways through the water, can be counteracted by a keel or other underwater foils, including daggerboard, centerboard, skeg and rudder. Lateral force
