I believe the answer is:

abandon

I'm a little stuck... Click here to teach me more about this clue!

'jump ship' is the definition.
'abandon' can be an answer for 'jump' (thesaurus). I'm not sure about the 'ship' bit.

'between ahab and oneself' is the wordplay.
'between' indicates the answer is hidden within the clue.
'ABANDON' is hidden within 'ahab and oneself'.

Can you help me to learn more?

(Other definitions for abandon that I've seen before include "Wantonness: desert" , "Forsake, leave behind" , "Completely give up; desert" , "Forsake with recklessness" , "Maroon" .)

I've seen this clue in the Sydney Morning Herald.
