Hello Mustafa,
Regarding all the eyebolts in the deck used for rigging, do you have a plan showing all the locations. The BJ instruction manual has a belaying diagram that shows circles where there are supposed to be eyebolts in the deck. There are clearly 4 at the foremast, eight at the mainmast, but the mizzen mast is very unclear. There are several "dots", but I'm not sure if these are supposed to be small circles or what?
Also, there is this photo that you posted above that shows an eyebolt in the middle of the deck near the mizzen mast.

Do you know what is attached to that? There is no indication that this should be there in my plan. Lastly, the belaying plan I have does not indicate what is attached to any of these eyebolts. Perhaps it is in the rigging instructions somewhere, but I have not found it yet. Thanks for help
