This is a huge plus for Garmin to me. Raymarine requires you to either push a button to disengage, or twist a little dial to change course. To my thinking, if I need to suddenly dodge a lobster pot the last thing I want to do is locate a small disengage button or a small rotary knob. Or worse, try to turn a locked wheel, then disengage the system. It takes time and precision. It seems much more intuitive to simply turn the wheel and have the system automatically relinquish control.I just upgraded to a Raymarine Evolution, but the one feature I really like on the Garmin is the Shadow drive. If you grab the wheel start maneuvering, the autopilot disengages, once you let go...it re-engages.
Raymarine doesn’t have that feature...
Also Raymarine - according to my last conversation with a rep - will NOT automatically make a when following a route. You must specifically acknowledge you want the system to make the turn and follow the next leg. Garmin will simply turn and follow the next leg of the route. Garmin also will follow a route created by autoguidance; IICR Raymarine said they did not but I could be mistaken on this point. This info was as of late 2018.
