BOMA DOWNHAUL:

To resolve this problem with adjusting the tension of the downhaul, which requires the return to earth or difficult balancing acts in the water, I realized this device. E 'format (photo at top left) by an actuator in the right hand that set the boom allows it to escape + or-the jack on the left, as shown in photo at top right the jack is completely enclosed in a maximum left, while in the photo at top left is the position for sailing cazzata maximum. This allows fine adjustment in gait with a range of 30 mm. The advantages are in the process of trimming of a new wing, to avoid a number of returns to land and change the trim of the sail in a very short time, so as to immediately verify the voltages with sea conditions and wind identical. Furthermore, if we have a friend in the water, to keep it as a reference and moving the downhaul see if there are improvements in and / or the speed by changing the tension of downhaul during the same board. During a competition or earlier if the wind conditions change, adjust the tension of downhaul to changing conditions, always in the race to change the tension between upwind and downwind.
