I'm guessing this refers to the NE corner of Deadman's bay.

Topography can cause the wind to bend around headlands. Manchioneel bay on Cooper is a good example - boats are frequently pointing opposite to the prevailing wind (current plays a role too).

Basically whenever you anchor so that you don't have adequate depth through the whole swinging circle you need to be thinking of the possibility of backwinding.
