With national survival on the line, creative bookkeeping or just outright cheating would be in defacto, but who will foresee the need for stouter hulls, unit machinery,
and a more robust torpedo cellular defense in 1933? The Sea Lawyers will insist on treaty compliance to keep the spirit of international law alive. That would be more important to them than a 23,000 tonne Yorktown.
So... speed and a tight turning circle and what was done as a TDS to resist a 200 kg torpedo warhead is seen as the best under the conditions pre iouvalent.
