Help rigging square top main

I had some sail maintenance done back in November and still have not gotten the rigging that fans out the square top of our main correct. It's a bit saggy on the leach.

I can't find any technical articles on how the thing should be rigged and the sail loft took it down before fully understanding so it could be rigged correctly!

Any help here for this specific application or square top insights in general.

Re: Help rigging square top main

I searched high and low for this very thing. My square top dynema broke while crossing the atlantic so I could never see how to fix it and someone on board just tied it up so the sail has not been right. I am really glad you shared this!!

Now that's interesting as I think my L450 is not rigged quite right. We had a lot of stress at the attachment point D and it tore the sail at the luff area by the batten.

Re: Help rigging square top main - different issue

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...

It was one of the first things I changed out on our 450 - to a fixed 80mm block at the sail top. As for installing swivels at both ends ..... me thinks that this could back fire as halyards stretch and rotate with time - not needed. My philosophy is have a fixed block and the halyard lines to the mast top block straight without any twists. Its one of those things you need to keep an eye on.

Re: Help rigging square top main

Our main halyard frayed nearly through at the top but I could not be sure why as it appeared to be just inside the mast from the mast block. However I locked the blocks rotation attached to mainsail and has been good since.

Re: Help rigging square top main

Thanks. I was inclined to do that (have both sides fixed). We shall try that and see.
