i'm not far from Precisions supposed "home" so i picked up the phone, and talked to "Darryl" who seemed quite knowledgable (in my ignorance, maybe). We talked for quite a while, and he offered me even better prices than they had on their website because i was so local...
He talked with great familiarity about my cruising grounds, so i'm positive he was on the up and up about where he was, etc.
He said that he'd email me a measurement form, and within 10 minutes, i had it, and it's quite professional and detailed looking (i'm looking for a new jib). i was pretty much ready to head up to the boat for the exact measurements his form wants, and i came across this thread...which surprised me.
i emailed him a link to this thread and said that i'd be quite interested in his comments about it.
So...i'll try to get back and let you know what happens!
