Dave Gerr - Boat Mechanical Systems Handbook-How to Design, Install, and Recognize Proper Systems in Boats

is in order from largest turning circle to tight-

est turning circle. Remember there are many

variables in the rudder installation and in the

boat itself, so this is at best a rough guide:

• MacLear Thistle rudder


• Schilling rudder and articulated-flap
  rudder


• Rotor-Rudder, double fixed-geometry
  unison rudders
  
  
  • T-rudder (Rotor-Rudder with articulated
    flap), Kitchen rudder, double fixed-
    geometry variable-control rudders
  
  
  
  

Again, very broadly speaking, the com-

plexity and cost of the rudder increases as the

turning circle decreases, and all of these rud-

der systems provide dramatically smaller turn-

ing circles and better low-speed control on

displacement than standard rudder vessels.
