Based on the information within,
we can conclude the cover with the censorship mark
was posted aboard ship, that raises the question why stamps were attached at
all?
Forces mail posted aboard ship was free, and no stamps were required.
I smell a philatelist creating some hokey pokey.

Covers without the censorship mark wre posted ashore, thereby avoiding
censorship
but requiring postage.
