If you are talking about my video I posted, the vang main sheet and traveler are all completely slack. I have no intention or interest in pulling the cringle down tight to the boom. I have it set up to pull the tack and clew reef cringle down to a point at this about 4"-6" above the boom. I have found that trying to get any lower than that causes the lines to run off the sides of several blocks which just increases the friction.Hayden, you have to loosen the main sheet (& vang) to allow the reef line to pull the boom up to the reef cringle. Your halyard was too tight which is why there was space between boom and sail. You'll pull that reef cringle out on a typical production sail.
The halyard mark is set to hold the tack cringle at that fixed height above the boom and corresponding blocks so that the lines at the tack will run fair through the blocks allowing the tension to transfer to the clew through the blocks inside the boom. I then crank down on the winch until I get the sail tensioned along the foot to establish the flatness (reef outhaul) that I want. I then retention the main sheet to set twist and traveler for angle of attack.
As for pulling the reef cringle out of the sail when hauling it down, the degree of load put on the cringle by the winch is far less than what the wind will put into it once the sail is retrimmed. I have never seen a sail cringle pulled out by hoisting but have seen many shredded by the wind.
If you actually meant that the sail could be torn by the reef lines at the reef points which are located at several places along the it should be noted that I do not have any lines tied into those cringles and never will. My new sail was ordered without them because I will not ever use them. Before I purchased Papillon the mainsail was torn in two right along those reef points due to either a break or uncleating of the reef line which put those reef points into tension and the sail is not designed for any vertical tension in those tiny little patches.
