The word straight from Fun in the Sun on the 2011 AHPC C2 models (thought I would ask instead of speculate ;-):

"AHPC has been in the 2011 model since last September, as such any boat delivered since are the 2011 model. Difference between in the C2 2010 and 2011 models are minimal, no hull or foil changes, but more options exist in rigging and accessories. Harken hardware has been slowly switch to standard, synthetic trap lines, as well as many other personalized options are available. Constant improvements are being made in rigging and layout based on user feedback.

To date we have delivered over 25 of this model, with 15 or so more being delivered in the next two months."

So yeah, guess they / we (full disclosure, I'm an AHPC rep) have been pushing them out the door pretty damn fast.
