I'm pretty sure I've seen those at VectorWorks Marine's shop
This can well be the case.
You know what would be the best setup in my opinion ?
Catamaranparts rudderblades, stocks and U-connector with the AHPC rod setup.
The AHPC supplied rod setup with stainless steel backing plates is just perfect. The handle (stainless steel tube at the end) is just the right size to allow for easy engaging of the rod setup and the head of the pin is rounded so it slides very easily into its locking hole even when the pin is not perfectly aligned with the hole. Also the heatshrink cover over the glass rod is very nice. Look good and takes care of all and any problems concerning glass rods. Also the dimensions are just right, You don't have to lean back far over the back of the boat at all.
Then the Catamaran parts rudder profile is the best so far in the F16 class. And it better be because it is used on quite alot of other boat types like the A's.
Personally I think the carbon stocks look cool, but the alu stocks are far more degradation (=UV and sandblasting) resistant and cheaper to produce. They weight as good as the same anyway. So again I must say that there doesn't appear to be any reason to make use of carbon cloth in the rudderstocks.
That would be my perfect rudder setup for the F16.
