1. Is this modification the AHPC system or something else?
Neither Robi's system or the replacement for the McKenzie setup are the AHPC setup.
I did see the setup that is going onto the EU Blades; actually a Taipan 4.9 sailor overhere bought these as a replacement for his older stype alu AHPC setup. I held and looked at the stock then once and they seemed pretty well done. This Taipan sailor has been sailing with them for a while now and is very content with them. I'm not sure wether the same setup is going onto the US blades.
2. Is Robi's new "bad butt" system the same thing that is now supplied on the production Blades?
Certainly not. I'm told that Robi's system includes a tube being laminated into the stern section. Probably to take a lock down line. This is a source of concern (leaks ?) and it is too expensive for production hulls. When done right it will be a fine system but from a economic point of view it is not attractive. And lets face it, the builder needs to earn a profit on these boats and we, the buyers, are not really willing to pay much more.
