Need a photo or 2. I think all Lazy jacks have to have some way to adjust. Otherwise you could not raise ( or lower, more accurately) the boom.We were able to raise the main yesterday without an issue...but re-reading the above two replies, I cannot see how we would add slack to the lazy jacks without having a ladder on our cabin top..the lazy jack lines are connected well above the boat at the mast then the lines comedown to a connection point several / 3 to 4 feet above the boom, then they attach to the mast above that....I can raise the topping lift however and put slack in the whole system including the boom, and the lazy jacks...any thoughts are appreciated as always...by the way.. there is not a cleat on the boom..there are adjustment rings for the lazy jacks well above the boom, but that would be a bit treacherous to adjust...btw....this is the connection point I refer to abovePatrick
