OK, now I realize where they are located and their use.They’re tied along the edges of the topsails, 9 on each. 4 along the top, 4 along the bottom and 1 half way along the bottom part beside the mast side. The rigging line runs through them and the sail corner blocks.
I think that loops of the bolt rope on the sides are "cringles" which do not pass lines through the sail but to the side. Are "earings" reinforced holes through the sail corners? I'll have to look closely at the sail plans for locations and form.
I do see and have a photo of the clew iron with two or three such holes located in the far outboard end of the main sail and is noted on sheet 6 which I will have to spend some time studying. Thanks, Rich
