Double Braid Twist Question

[Dave R]

I've been having a heck of a time trying to eliminate the twist in my peak halyard. Does anyone have any ideas?

The halyard runs from the peak of the gaff to a double block on the mast. Then is runs to a swivel block near the mid point of the gaff, back to the double block and then down to the cabin roof and aft to the cockpit.

I suppose the reeving through these blocks on the mast and gaff would be considered spiral reeving.

I assume the twist is actually distributed throughout the halyard but it shows up in the legs between the double block and the mid-gaff and makes it difficult to raise the peak the last foot or so.

I also have the same sort of problem with the throat halyard but it doesn't seem to be as bad. I've tried to straighten the line before setting up but it doesn't seem to improve.

Any suggestions would be greatly appreciated. Thanks

Dave
