Wind vane self steering from Mister Vee

Mister Vee self steering started out from a need to solve a particular mounting problem, on a small boat with a centrally mounted outboard engine.
Even though the resulting system (Mr. Vane) is no longer on offer, its legacy is still at the heart of Mister Vee windvane self steering.

After Plastimo stopped manufacturing Navik self steering systems, Mister Vee got permission to make replacement parts for Navik.

"First of all I'd like say, I am very pleased with my Mr. Vane which I
finally mounted on my Hurley 22. It worked perfectly on the first try."

 

Main Features:

Super precise steering

How?

The combination of design choices and low friction materials gives a very responsive system resulting in steering with very little zig or zag.

This is most important in low (apparent) wind conditions, especially on off wind courses.

Single size UpSideDown Windvane

Mister Vee is the first and only company to offer systems with a single size size windvane blade that rotates underneath its axis. Why is this important?

On down wind courses with little heel a normal vane has maximum steering ability which is mostly not necessary and can easily cause oversteering which results in a zig-zag course.

USD (Up Side Down) windvanes are better suitable for down wind courses: less zig-zagging is safer.

This discovery was made by Dutch wind vane steering expert Jan Alkema who published his findings in sailing magazines and on the internet.

Low weight

From the start, the Mister Vee design was aimed at reducing weight. Finding ways to use modern plastics instead of metals had a huge impact on weight and ultimately, sensitivity.

Materials

Besides plastics, of which some are fibre reinforced, other parts need properties that plastics cannot meet.
Where mechanical requirements or cost effectiveness dictate it, stainless steel is used. Where possible this is 316 grade.

Standard parts where possible

One key way to keep costs down is to use standard parts and materials wherever possible.
This is very visible in the Mister Vee UpSideDown windvane.
Because of its design it only requires a small counter weight and its weight needs to be precice . Where every other system utilises a big lump of lead which is hard to tailor to a precise weight, Mister Vee use a stack of stainless steel washers, a very adjustable yet cost effective solution.

Super sensitive+UpSideDown=Stable course

Because of the lower overall weight, using acetal/glass ball bearings became possible. By using these in almost all wind driven axis, the Mister Vee self steering systems are possibly the most sensitive systems around. But why would you care about that?

Windvane self steering systems use change in the direction of apparent wind to steer the boat. The lower the friction in the system is, the less (apparent) wind force is needed to start working.

This is why you get just one windvane size with the system, where some brands offer a light weight bigger blade for light airs.

Mister Vee systems just do not need this larger windvane for light air performance, nor does it need a stronger blade for more wind. Since the start in 2006 the number of replacement blades ordered is zero. Naught. Null, 0.

The wind from behind is the most challenging course for any windvane self steering system. Look a the clouds behind the windvane and see how quickly and smoothly a Mister Vee self steering system controls your boats course:

Customisable

The way Mister Vee systems were designed differs a lot from conventional systems.
As a result the individual parts are simpler and this makes for very easy customisation should you desire it. You can have this done for you or do the work yourself.

"All in all, the self-steering system is a well-engineered piece of equipment and I am quite pleased with the design and workmanship. Well done."

Available models

Mister Vee currently carry one product line:

Mister Vee Y&B self steering

Y&B, the only available windvane self steering system below 10 kg/22LBS.

 

New systems are currently on the drawing board.

These systems share the majority of the mechanical components and when mounted correctly will offer similar performance.
They differ in the options they offer for mounting.

The Standard version of Y&B includes a super versatile mounting kit that allows for most transoms.
Y&B can also be easily be customised to suit a particular mounting need.

Bonuses in the Mister Vee designs

Theft prevention

Both the windvane and the pendulum rudder can be easily removed from the system. The valuable bits can be stored inside the boat without any hassle.
Overload protection
The mechanism that lets you disconnect the pendulumrudder also releases when the pendulumrudder is struck by something in the water.
