New website for Mister Vee in 2015

Over the next months the Mister Vee website will be replaced with a brand new one.

Here is what may happen during the transition:

- The website may also be off line for longer than during normal maintenance
- The website will be read-only for a period of time (no orders can be placed then and no new accounts can be made)
- Only limited data will be transferred to the new site, so things may not work as you are used to.
- And maybe other things too...



When trouble shooting your windvane self steering, it is good to know what we are talking about.

So here are the most important terms in a drawing.

1 Mast rotation

This is where you set the course. In this drawing the course is set for wind straight from behind

2 Windvane axis change

This setting changes the sensitivity with which the system responds to changes in wind direction.
The change you can make is from 0 degrees to about 30 degrees.
When you change this setting you actually change the angle to horizontal around which the windvane rotates. This axis is set at 20 degrees off horizontal when windvane axis change is 0 degrees and with newer systems is limited to 50 degrees, at which point windvane axis change is 30 degrees.
Systems prior to 2013 can have a change applied up to 70 degrees, at which point the windvane axle is upright. At that setting the system would no longer steer.

In the drawing the angle has been changed to 30 degrees.

3 Windvane swing

This is the result of a change in apparent wind direction.
It is mechanically limited to roughly 55 degrees to either side.

4 Pendulum rudder rotation

This is the result of the windvane swing.
The AMOUNT of pendulum rudder rotation depends on windvane axis change.
The more Windvane axis change has been applied, the smaller the pendulum rotation becomes.

5 Pendulum swing

This is the result of the Pendulum rudder rotation.
When the Pendulum rudder rotation starts, the pendulum immediately starts to swing out.
The further the pendulum swings, the smaller the pendulum rudder rotation becomes.
