With all the waypoint questions lately I have one question. When navigating to a waypoint when have I arrived? Is it when the tip of the boat icon touches the waypoint, when it's over the center of the waypoint circle? Ive also noticed that when zoomed out it will look like you arrived but if you zoom in it steps back again and you are no longer on the spot. Is it best to use the arrival alarm as an indication rather than the boat icon?
