I wouldn't recommend you change to a fixed block as reckon you need the swivel to help it align on different points of sail. We have the same problem but have solved
it by the person at the mast, after they have shackled the halyard to the sail, holding onto the cheeks of the block as the tension is taken up on the halyard then as it gets out of reach pulling down on the luff of the sail until enough sail is up to add some weight. This keeps the halyard under tension and stops it twisting.
If I'm on my own I use one hand to tension the sail and the other to raise the halyard pulling it out of the exit box and standing on the rope
when I have to change grip.
None of the above is pretty but it works. Prior to this I had a problem one time when I hoisted the main with a twist in the halyard which jammed at the top and the sail wouldn't lower so am now much more careful. I did change the FP provided halyard for a much better quality rope
after hearing about 2 boats that had their halyards part at the top.
If anyone else has worked out a better method for stopping the problem would love to hear it.
