Our (new)
halyard parted at the top - where it enters the
mast on its way down to the
cockpit.
A rigger friend said that this happened as a result of the
mainsail head block being allowed to swivel and that I should change the block setting to the 'fixed' position.
Basically he said that as the line is fixed to a shackle on
mast top and the block is allowed to swivel the line gets twisted and chafes at the mast entrance.
Another friend, a professional
skipper, advised to put both points on a swivel, (the start of the line on the mast
head and the block on
mainsail head) with the hope that if everything swivels no twist will be introduced.
Any input will be highly appreciated...
