[C320-list] Raymarine Evolution EV-100 Wheel Autopilot

[Jack Brennan]

Hi Ian.

No rudder sensor. Under most conditions on the 320, the king spoke on my wheel is maybe a couple of inches to windward, indicating slight weather helm. I don't see the need for it.

Jack do you have a rudder sensor on your boat I think that makes a lot of difference. I don’t but that said, other than in trailing seas of 1 m or more my EV 100 works great and we get some pretty crazy stuff down here in New Zealand. The pilot even works fine with a Asymetric up at 7 odd knots.

Looking for any user input from those that updated to the newer Raymarine Evolution EV-100 Wheel Autopilot. Did the newer wheel drive unit significantly improve over the ST4000 or should I bypass the wheel drive and go directly to a below deck steering system?  Plan to sail off-shore Fl and to the Bahamas.
