I bought a spinnaker to use on my M15. I have a couple of questions for anyone who may be more experienced than myself with using spinnakers. (I never have!) I need to attach a block to the mast for the spinnaker halyard, above the forestay attachment. Does anyone have an idea how far above the forestay the block should be attached? Another question is, what should I use as the attachment point for the tack of the sail? The same piece of hardware that the forestay and jib attach to? Finally, when rigging it, should I use a downhaul or some other rigging other than simply the halyard and sheets? (I realize I'll want to use a whisker pole to the clew, right? If any kind soul would take it upon themselves to educate me in this matter I would be most grateful. Steve McClellan~~M15~#152~~Chicago
