How does it work?

All Mister Vee self steering systems are of the servo pendulum type. This is how they work:

  • The wind moves the windvane (1)
  • That makes the pendulum rudder (2) rotate around its vertical axis (3)
  • The water flowing past the pendulum rudder makes it swing sideways around its horizontal axis (5)
  • Control lines (6) that are connected to the pendulum rudder and the boats main rudder make the boat steer back to the correct course, the windvane returns to neutral.

Have a look at the video:


But what's the point of all this?

Isn't there an easier and better way to keep the boat on course?

Better steering

No electronic device or other windvane self steering principle can match a servopendulum system in the quality of course keeping!


Due to some clever design by Mister Vee it was possible to use ball bearings in every wind driven axis, resulting in a very low friction in the transmission of the movement of the windvane. This means that our systems can steer your boat with less wind than any other system, on any course.

Isn't this a bit over complicated?
If the pendulumrudder couldn't swing side to side it would still steer the boat, wouldn't it?

Well, yes and no. It would result in a basic steering action. But with the wind from behind the steering action would not be enough for the subtle corrections that are needed, the boat would folow a zig-zag course. Servo pendulum systems from Mister Vee give the best windsteering action!
