I had a 6.0NA and it definitely did not have a self-tacker. It had that jib that would "make you slap your mama" on a reach.
Nothing like a 5.8N/A or a 6.0 on a screaming reach with that big ole jib.
AZCats boat one of kind, well in his case 8 of a kind.
There are a few other 6.0's running around here we refer to as Roy's Toys. There is one where he had moved the bridal tangs to the front of the bows with a custom made slag of stainless steel the looked like something out of Mad Max, put a gargantuan jib on it, raked the dickens out of the mast, and swore it didn't need a spinnaker. I seem to recall Team Chums beating him back with his H21 w/spinnaker - he just forgot to take in down once inside the harbor and got disqualified from the race. There is another one where he took a 5.8 (the boat he designed) lengthened it to a 6.0 gave it 9.5 foot beam - the true Frankinboat. One day the owner and I took it out and drove it hard, that thing hauled butt!!!
