In the pic regarding a plumb line, I am more interested in your sail: I just acquired a "new old " main that has a rope bolt rather than lugs, like my old - old sail. Due to lack of free time and low lake levels, I haven't drug Tiger Lilly out of storage to try the new sail. Your sail appears to have the rope bolt AND lugs... makes me wonder if the rope bolt will work with my mast, or if I need to modify either it, or the means of affixing it to the mast in a manner that allows for (intentional) sailing... was this an issue you had, or was this the set up you acquired?
