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...
