By this technique of tortuousness into the wind it is probable to arrive at any upwind objective. A vessel whipping to a mark in a straight line upwind 1.6 km absent will cover up a detachment from side to side the water of at smallest amount 2.3 km if it can tack from side to side an angle of 90 degrees with insignificant flexibility. An old saying explain thrashing as sailing for twice the remoteness at half the speed and three times the uneasiness. When beating to breeze constituency one fastener may be more favorable than the other - more in the course you wish to journey. The superlative plan is to stay on the positive tack as much as probable. If the wind transport in your task called a lift then this fastener is even more positive.
