...Pretty much the leech load on a large squaretop sail is about 400 kg. If all of that or most of it is taken up by the batten then you would simply push the batten through its cap on the luff and jam it into the luff rope and sail track...

I do not understand the forces on a batten that would push it through its cap. It seems like that would require a force parallel to the long axis of the batten. Would you elaborate on the physics of this statement?
