Steering Mechanical Design

I may have mentioned some of the details before, but here is a drawing of the mechanical design for the steering system. It shows the side view from the cockpit to the rudder. This will be a direct drive transmission steering system, instead of the typical cable driven push/pull idler system. It uses a system of transmission shafts, u-joints and bevel gears. Advantages are...
  • more reliable (no cables to wear)
  • solid rudder feedback (very little "play")
  • more compact (no large quadrants, pulleys)
  • easier to install (the transmission tubes could be run just about anywhere).
The parts will be made by Jefa Steering Systems. The system is similar to the Lewmar Mamba System. Hopefully we will have the system coming together by summer.
