ESSENTIAL GUIDE TO SAILING WITH INSTRUMENTS
Wind What’s so important about wind information? Every sailor needs to know which way the wind is blowing from in order to make even the most simple manoeuvres and route calculations. The wind can make a difference between a great journey and a terrible one. The Wind Triangle The derivation of wind direction is best described by the “Wind Triangle” which shows the relationship between boat speed, the Apparent Wind (the wind
you feel while sailing along), the True Wind (the wind relative to the water surface) and the compass heading of the boat.
