My boat came with the asym spinnaker which I doubt has ever been used. The hull did not get all the extra pieces you see in the kit. First let me state, I do not intend to use this sail at anytime in the near and even maybe the distant future. My mind wanders some and I was thinking how I might use the sail with what I have on the boat now. I can attach the head to a halyard running through one of the 2 blocks on the leading edge of the mast, probably the one with the swivel block. The tack could be attached to the fitting on the bow where the jib drum attaches. I am thinking I would have to add some jamb cleats in the back somehow for the clew. I would think I would have to copy the set up from the factory. Would there be another way? Keep in mind this is not very important, I was just trying to figure out what might have been thought of by whomever bought the boat. I am the third owner and I know the second owner never used the sail. So I guess the original owner had intended to use it but never bought the kit for using it. Or maybe there is a box of parts laying around in the guys basement.
