QB2 fitted the B2 class.. This was probably started by Neil Fowler in Darin with his Black Witch class. The class rules were 18x8x225

QB2 was a modified A hull. Cunningham had an old Proctor built Cunningham A class platform. After work Cunningham and Proctor took the deck off the A tweeked the bows and put on new beams. Bruce Proctor still around with lots of info.. He says his recollection B2 because it was like a B class but you couldn't call the class B2/3!!
Brian Cronin from Supreme Sails sailmaker. Bruce was the main builder and has all the numbers and names in his files.


The first boat was sailed by Bruce Proctor/Barry Marmion? at the one of a kind regatta Frankston. Dry land tuned and won her first regatta.

I believe the stingray class is a B2.
