Stocks = rudder castings, the things that take the rudder boards themselfs and secure them to the sterns and link them up to the tiller bar. Of course you can't cast carbon so the name had to be changed into something else. The Aussies called these things stocks and so we started calling them that way too.

See below a picture of the AHPC carbon rudder and carbon stock as used on the Taipans. The Blade design uses a similar design. I believe it has been redesigned for the 2006 Blade, so it is different from the early carbon stock option that were delivered with the Blade (2005 and prototypes), Same applies to the rudderboard itself.
