Hi,
Yes, the line runs "bare" through the grommet and down to the Jr Jam Cleat ..... or to that padeye on the port side down low. On a second look/thought you maybe currect that the "cheek block and Jr Jam Cleat maybe used together to give you some mechanical advantage and cleat for you jib halyard. I'ld have to see your halyard to determine that. Do you have a pulley up high on the forestay? Is there a 1/4" length of line attached at the end of the halyard??? How long?
That system would be a rudamentory "Jib Luff Adjustment".
I think you need to see my P19MX ... it has the up-graded systems (adjustable from the trapeze)that can be installed on your boat quite easily and fairly cheaply.
Small Steps ... one at a time.
At this point, I would suggest that the first priorities be that you purchase/install the "Over Rotator (Controll) Arm" since you have NO Over-Rotation at all, next up-grade your downhaul system. The "Arm" is the cheapest, quickest upgrade and really helps the boats downwind speed. The downhaul will be slightly more expensive w/ the additional "exit block" for the other side being the most expensive part plus some other misc parts. After installing them, then I would consider changing the "Jib Luff Adjustment" system over to something like mine that is adjustable from the wire/trapeze.
Keep in Touch ..... maybe I can stop by and see your boat sometime. I can route myself over the Francis Scott Key Bridge when I'm headed south to Gibson Island or Annapolis ....
