I rigged the cunningham according to the information on this site and the sunfish bible. However, I ran into a problem. After I tied an eight knot in the 1st grommet above the tack, the instructions say to run the tail through the eye on the plastic cap on the end of the lower boom. However, the nut which holds the eye bolt on the lower boom is just behind the cap and is in the way. There is no way to feed a line through this because of the nut? The nut came with the boom. Any thoughts would be appreciated.
