OK - here is one more that I know I'd like some help with and maybe Tim will too at some point. I downloaded from the Performance site the PDF file for the Nacra assembly manual that like you said seems to apply to most all models. On page 27, step 61 they talk about installing the jib sheet jam preventor, a 7' piece of stretch cord. Somehow you are supposed to attach it to the mast, somewhere, and then down to both ends of the dolphin striker.

Did you ever need this and if so any hints on how/where to put it on the mast would be appreciated. The PDF download does include a photo but it is so blury I can't make out what they expect.
