[DG] EV autopilot questions

[Derek - Raymarine - Moderator]

Hi Serge,

Thank you for your enquiry.

The EV pilot works extremely well without a rudder reference unit, due to the performance of the EV sensor and the new control algorithms we use.

Having said that, a rudder reference unit will always improve performance - it will provide a very accurate position feedback of the rudder and will eliminate any issues of noisy back emf caused by worn motor brushes and electrical interference from other devices too.

Regards
