Most airplanes have drive and drag aligned. Picture an airplane with the engines mounted half the wingspan above the wing. That is the analogy for a HP in light wind. The centre of drag could be windward of the centreline and the drive is on the lee side of the lee hull.
If CLR and CoE are aligned laterally the HP with have weather helm because the drag on the ww hull is so far offset from the drag on the lw hull.

A slight weather helm is desirable for safety, but best performance is a fully balanced helm.
