Why a machinery-space torpedo hit doomed HMCS Athabaskan

Why is the claim that a British motor torpedo boat sank HMCS Athabaskan implausible?

The attack direction points to the German torpedo boat T24, and the fatal central hit exploited the destroyer's large machinery compartments.

The torpedo's direction points to the German Elbing-class boat T24, identified earlier in the reading as Athabaskan's attacker, rather than to a British motor torpedo boat. Preserved Tribal-class machinery spaces explain why the hit was so destructive. Boilers and engines occupied large compartments spanning nearly the full beam, which made a central underwater explosion much harder to contain. Hits forward or aft met more subdivision, so the same weapon could create a very different survival problem elsewhere in the hull.
