The Halyard diverter wheel is used to increase the angle between the forestay and halyard as an alternative to a mast mounted fairlead. This reduces friction, provides smoother furling and considerably reduces bearing wear. To convert our wind pressure into halyard load, we need to calculate the forces involved using a vector diagram. A rope that is too long increases the chances of getting tangled, adds to the overall weight of the boat and it's just a waste of money! I - Height of Foretriangle Elevation of Forestay, measured down to elevation of main shrouds at sheer line. Genoa sheet/halyard load calculator To calculate loading on a genoa lead car, the deflection of the sheet should be taken in account. So, consider wind speed in your region and its load on the pole.
