The proper CRUISING SPI hoisting is the following : A ) connect the hank to the forestay – B ) connect the downhaul – C ) connect the halyard – D ) connect the sheet . When the sail is hoisted , adjust the tack point ( with the downhaul ) at nearly 50/70 centimeters from the deck , if the wind gradiant decreases haul in the sheet and the downhaul , whilst for wind gradiant increasing release both conseguentely.
