The weather-beaten skipper's last order? (7,4)
I believe the answer is:
abandon ship
'the weather-beaten skipper's last' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'order?' is the wordplay.
I cannot quite see how this works, but
'order?' could be 'ban' (ban is a kind of order) and 'ban' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for abandon ship that I've seen before include "Leave a sinking vessel" , "get into lifeboats" , "Go overboard" .)
