I'm thinking about adding a spinnaker to my 1990 Hobie 18 magnum, but I'm concerned about mounting a tang to my comptip. Any advice? I see spinnaker kits in the store, but I don't know what's in them. Do they come with instructions? If I start working with a local dealer, it looks like I'm going to spend $2,000; that's more than the boat is worth. I just love the wings and do not want to give them up.
