Never having used a bosuns chair this might sound like a dumb question but here goes anyway...
I am thinking about what it will take to properly rig a sailboat for singlehanded sailing. I was thinking what would happen if I needed to fix something at the masthead (and the gear required).
This made me think about ''what if I needed to repair/replace the forestay tang'' (or fix/mount something otherwise on the foward side of the mast).
Hauling a bosuns chair up (using a climber, etc.) using the main halyard places you on the aft side of the mast. Thus it seems that gaining access, working on something on the FORWARD side would be particulary difficult, *especially* at the masthead where you have only a very short length of halyard remaining between the chair and masthead sheeve (i.e. preventing one from working their way around forward).
Am I missing something elementary here?
