Apparant wind

When travelling down wind, it seems to me that there are situations where the apparent wind direction can be the same and even move rearward? The course material indicates that it is always forward? Am I missing something

It is always coming more forward than the true wind. more forward does not mean from the forward part of the boat. ie if true wind is 150 relative to bow then apparent wind might be 135 relative to the bow. Of course if dead downwind then the directions are same but apparent is reduced in magnitude over true.

Right, I think that could be clarified in the module - for example one of the questions works through the true wind at the top of the mast being 'behind' the apparent wind at the boat, due to the increased speeds from the wind shear - 'behind' is being alluded to speed rather than closer in DEGREE to the true wind heading.
