We have another concern on the T...
The T runs a fairly high bridle/forestay intersection. The new jib passes below this point all the way down to the pole. There is a strut running from the end of the forestay down to the pole...about 1.5' long. This is attached to the pole with a clevis pin to the jib tack point bracket. So, any significant pole rotation will bend/break the bracket or the strut itself.
all my spin poles (I20, F18, N60) have been allowed to rotate with their main beam mount...no problem. The Nacra system uses a 3/16" pin sticking straight out from the main beam and the pole simply has a hole in the end cap. No retainer either.
