Why joining Zulu and Nubian made sense

Was combining the surviving halves of HMS Zulu and HMS Nubian the right repair?

Yes; the splice created a serviceable destroyer, however odd, and even distorted German estimates of Royal Navy strength.

HMS Zubian joined the surviving bow of Zulu to the surviving stern of Nubian after each destroyer lost the opposite end. The repair made sense because it returned a functioning ship from two otherwise unusable casualties. The hybrid appearance and changing reports also helped convince German analysts that Britain possessed secret destroyer-building capacity. The result was material improvisation and an accidental source of enemy intelligence error.
