It looks like they attach a D ring to the primary winch using a sail tie. To that ring they attach a turning block. Run the sheet through the turning block, then up to the secondary on the opposite side.
Dunno what they do for spinnaker winches when they get to the top mark... use the halyard winch temporarily? Dennis, We hoist and cleat the Spinnaker at the mast.

So, ahh.... just what is the safe working load of a North Sails Sail Tie? I'm also trying to make sure I understand how the sail tie is secured to the primary. Just a loop around the barrel of the drum? How much load is being put where on the drum? I'm imagining most of the load is sideways, effectively in directions the winch is expected to handle, but some must be vertical, effectively loading up the top locking plate and the snap ring (Not that we don't end up with those sorts of loads on winches from time to time anyway)
I'm just trying to understand the implications of playing with loads like this, so we can do it safely.

I've never tried a cross-sheeting set-up, so please forgive my ignorance.
Why not just put one wrap on the leeward primary, and then cross over to the windward secondary or even the windward primary? Why does one need the turninng block?

Is there any reason that cross sheeting is to the secondary winches instead of the primaries? Don't the 24's go from the Lopez block to a primary?

The 24s us the Lopez blocks which frees the winches. If you have the block on the primaries then you cannot use the windward winch since it also has a block on it.
I think a Lopez all the way aft on the Genoa track may work.

Dave, I think Dennis was asking about trimming not hoisting the chute. Cross-sheeted genoa would be on same side as afterguy. What then?
BTW Zephyr's current cross-sheeting method is IMHO within the rules which give latitude on use of blocks for trimming. I believe it was the metal mounting bracket moving the winch aft that was ruled illegal, though I only saw pictures. News to me that simple strip of metal to protect the gelcoat from chafe would be a problem.

Dennis,
What was your specific question about the Spinnaker? I am having a senior moment.
Bob,
Yes, the position of the starboard side seconday was the issue. It was considered an unapproved modification. After the class ruling, we moved the secondary back to its original position, but used a pad which was approved by the class.
Again, there are many ways to skin this cat. Simply get the weight on the high side.
Regarding the sail tie question. We tie a block with several wraps around the primary using a North Sails sail tie. North makes the best sail tie in the industry. Just kidding. Pretty low tech huh?

Well back to the original intention of this thread (good tangent on cross sheeting though!)...I corresponded with Benz today and asked if he would work with Henry Little at the RI North loft to share his secrets for having similar sails made at Zephyr's local North loft. Benz's reply is; "...I consider the J-30 as a one-design boat and yes you can order the sails through Henry however past experience is the sails do not come out like Scott's sails even though I have tried to share my designs with the North designers. I can only guarantee this to be so when the sails are ordered here. I can assist you with a great tuning guide which will match the sails ...." So my dilemma is to figure out if I want the recipe repeated without the local support, or the potential of duplicating the recipe but with local loft support. I'll be speaking with other folks too, so feel free to weigh in with your comments and recommendations. Bill

Bill I am having the same issue here in Marblehead. Seems the reason you work with a large sail maker is to access shared design ideas but that seems not to be the case with all North lofts. I am sure Benz is getting benefits from being part of North Sails, he should give back to it without friction. I can understand people who do not have access to a local North loft buying from Benz, but the people who have a loft in their own town need to support and need the support of their own loft.
