[DG] [DG] EV150 Autopilot

[Derek - Raymarine - Moderator]

Hi iRondo

Thank you for your enquiry.

The selection of Autopilot is based on the Displacement of the boat + 20%, the additional margin of 20% is to compensate for the normal plethora of additional items carried onboard, stores, extra gear, spares etc . .

This FAQ click here will give more information and will help explain specification.

You mention hydraulic steering? In which case the key to the correct autopilot is the cubic capacity of the hydraulic ram which drives the rudder.

I recognise you have a sailboat, and this link here is for powerboats, but the information relating to the sizing of pump to ram capacity holds true whether sail or power.

SO the first point to consider is the cubic capacity of the steering cylinder, once the correct pump is identified, then the correct ACU can be identified, since this is dependent on the pump. Then the EV1 sensor will be required as well as a p70s style control unit.

regards
Derek
