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.
