Based on my last Tradewinds regatta sailing with Krantz on my V1 Infusion vs. the newer C2 (flat water, 15-18k breeze), the infusion seems to have slightly better speed upwind and the C2 slightly better speed downwind. I'm gauging this against my performance with Robbie Daniels and Tomko on their C2s. I could out pace Daniels to A-mark on the first leg but would lose more than I gained on the downwind...initially I learned a lot watching him pass me downhill and discovered some errors I was making with my mainsail trim but, once corrected, it still wasn't enough to keep him from gaining more downwind on me than I would gain on him upwind. When we got off the line well, though, Tomko would usually slightly beat us to A out of glorious tacking execution (sight to behold) but I had nothing on him downwind...of course, sail condition and technique play into everything and I'm no pro. With the exception of my raggedy jib, my other sails are new and I have no idea what condition the sails were in on Robbie's boat. Tomko's looked to be pretty spanking new.

With regards to the original Capricorn and the Infusion, I would say that the Infusion is slightly more resistant to putting a bow in downwind but I've only sailed the original Capricorn once (never on the C2). They're both perfectly fast enough that the skill on board will be 98% of the win factor.

That said, after having to do some major structural repairs caused by poor build quality on my 3 year old Infusion, sailing a couple of Capricorns, seeing the Capricorn go through an Alter Cup (as well as the sailing the AHPC Viper in one), I can say that the AHPC brand gets a big thumbs up from me in build and fitment quality.

I've owned Nacras since I started sailing but, if I was in the market again, I would need to go back through my photos of all the work I had to do to fix the poorly mounted daggerboard trunk in my Infusion before I decided what to buy again.
