sailing theory

Sailing theory revolves around harnessing the wind to propel a boat across water. It involves understanding wind direction and sail shape. When wind hits a sail at an angle, it creates lift, similar to how airplane wings work. Sailors trim (adjust) the sails to optimize this lift for speed and direction. Key points include points of sail (the boat's angle to the wind), tacking (turning the bow through the wind), and jibing (turning the stern through the wind). Knowledge of currents and weather also plays a vital role in effective sailing.
