I recently purchased an O'day 23 in rough shape, I have been working on it trying to get it in the water before the end of the season. I have figured out most of the rigging, but I am stumped at how to secure the foot of the sail to the boom. There is a line with a small block attached at the aft end of the boom and one block 1/4 of the way back up the boom towards the mast with a cleat in front of it....Am I missing some parts here? My previous boat was a Santana 20 that had a small internal halyard for the foot of the sail....If you have pictures that would help!!!
