New ruddersystem for DNA

Finally we got all parts of the ARC designed  made in China rudderstocks.
The rudderstocks are made out an ARC designed aluminium tube with rounded edges.
The curve of the head is lightly smaller than existing designs. That results in a slightly lighter and stiffer rudderstock.
The  new rudders weigh less than 1 kg. The rudder is somewhat wider at the waterline to increase grip at the the start and during markroundings in traffic. The rudder is a bit shorter to decease drag of the windward rudder will doing the wildthing. The moderate tapered bottom helps to get rid of weeds.
