Why We Sail--"The Wheel Pilot, 2018"

The Raymarine EV-100 wheel pilot: quantifying its quirks and qualifications. Turn on [CC] (Closed Captions) for details. Regarding "auto tack": Why would anybody select a preordained tack? Why not select a 90-degree tack, or 100, or 110, or 130 degree tack? Who jibes 90 degrees each time? Why not do the jibe you want, of 40, or 80, or 120 degrees? Is is very easy to hit a single button numerous times. It's easier than having to look at the control head in an active seaway and hit two buttons simultanously for an "automatic tack" written by a software engineer. Isn't it?
