Autopilot Standby and Manual Override ?

Dear all,

I have a Raymarine ST7000+ autopilot with a type 300 course computer, and a hydraulic ram to control the rudder. Normally to disengage the autopilot, I hit STANDBY, then take the helm.

In an emergency could I take the helm and 'over-ride' the autopilot without hitting STANDBY first? Would this do any damage i.e. is the system designed to take these sort of 'events'? Or would the hydraulic & control system 'fight' the manual steering input?

Thanks for the help!

Michael

Not a good idea and pretty unlikely that you could override the hydraulic system. You may end up damaging the steering mechanism, it depends on how powerful the ram and pump are.

I do not think one can manually force/damage a loaded hydraulic arm. In fact I would expect the pilot can take action and break your bones, should you have your foot or hand in the wrong place.

You won't break the hydraulic ram, and probably not its attachment to your quadrant. But you could very well break a steering cable or cable anchor!

In short, don't do it!

Some autopilots have a "Dodge" button that disconnects the autopilot but it remembers what you were last steering. After dodging around an obstacle you tap the "Dodge" button again to re-engage the autopilot which continues on as if you never disengaged it.

I have a Robertson a/p. Switch was on auto by accident. Turned the wheel, felt some resistance, gave it a tug, and broke the tiller quite easily. As you can see from the picture, it was quite a substantial piece of brass. Luckily, no damage to hydraulics or anything else.
