The Nacra factory has revised the lower rudder casting to remove play and give steering a more precise feel. A higher quality, die-cast alloy is used, making the castings stiffer and stronger than before. One new feature is a Delrin plate which can be replaced to remove play when worn.
The new casting released in late 2013 is distinguished by the embedded Nacra racing logo. Nacra factory item #30114-2.
Fits Nacra 460, Nacra 500, Nacra 570, Nacra 16, NACRA 17, Nacra F18 Infusion, Nacra F20 Carbon and all Inters.
