Mast rake for current sail design is determined by side stay length (5m, eye to eye)
Windvane is mounted under the jib bridle, if sloop rigged, or cassette tape tied to the forestays if cat rigged (Twin forestays)
The saddle on your jib track is to secure the end of the jib sheet, which then goes to a pulley on the clue of your jib, then back to the fairlead and cleat, then across to the other cleat and fairlead, forward to the other pulley and back to the saddle.
Give me a call about your jib halyard, it is not the original setup. 0243591729.
