Perhaps it was supposedly a correction for seawater refraction, but the protrusion is angled off several degrees to starboard -- which would have placed the underwater damage too far forward on the Fitzgerald.
Also, per my visualization, the relative speeds (Fitzgerald considerably faster) would, at that point/instant of approach, had the ACX Crystal's 90-degree course in line with the very front of the Fitzgerald's bow -- not with the actual point of contact...
