A self steering system can be mounted off centre and it would give steering action.
However, steering ability may differ depending on the tack the boat is on, and there may be issues resulting from the off centre mounting that cannot be predicted.
That means that Mister Vee can not offer full support on mounting and use, and the system is not guaranteed to steer your boat as described in the terms of sale.
Windvane self steering can not cope with constant acceleration followed by slowing down. This means that it may not be possible to steer an ultra light displacement boat or multi hull.
A windvane self steering system uses the apparent wind direction to keep on course.
When the boat accelerates, the direction changes. The system will correct accordingly which will in the end make the boat slow down.
The course will again be corrected and the cycle starts again.
Ultra light displacement boats like Mini Transats generally are too fast to be steered by a windvane self steering system.
The boats apparent wind is cause by the boats speed as well as the true wind direction, and that makes course keeping unreliable, often resulting is big variations in course and continuous speed changes.
The power a windvane self steering system can deliver is directly related to the size of the pendulum blade, and the height above the water. The higher the mounting, the longer the pendulum rudder, the higher the force the system can generate.
But the the actual force depends on how light the boats steering actually is. An un-balanced barn door rudder will require more force to steer the boat than a fully balanced spade rudder. The lightness of the transmission in the rudder system is also a factor.
Navik self steering systems have generally been used for for smaller boats with tiller steering.
But as long as the wheel steering is purely mechanical, the forces that need to be generated are more or less similar to tiller steering, except for the power to accelerate the steering wheel, if very quick and rather big movements are needed.
So in general, a Navik should be able to steer a boat with a steering wheel.
With a servo pendulum, the blade will be unstable when reversing the boat and it will want to swing to the side.
If it can do so freely then there is no problem. It will float to the surface and will not affect the boats manoeuvring.
But it is very different when the pendulum rudder can not float to the surface freely.
The swing can be limited by design, like with monitor, Aries and Beaufort self steering systems, or by set-up, for instance the steering lines do not allow a full swing.
Generally, No, unless there is a bypass valve and an emergency tiller option.
The servo pendulum systems that are on offer from Mister Vee can not overcome the internal friction of a hydraulic transmission of steering input. Only auxiliary rudder type systems, which Mister Vee do not offer, will do in this situation.
A boat with a centre cockpit requires longer steering lines and more guide blocks than a boat with a normal cockpit.
This can easier lead to more stretch and less responsive steering. Combining that with wheel steering kan make things even more complicated.
On a wheel steered boat there often is a reduction between the wheel and the rudder. If that reduction is done with hydraulics, Mister Vee do not offer self steering for your boat. The hydraulics have too much internal friction for a standard servo pendulum system to overcome.
