Tom's bit of naval experience (6)
I believe the answer is:
cruise
'tom's' is the definition.
(Tom Cruise)
'bit of naval experience' is the wordplay.
I cannot really understand how this works, but
'bit' could be 'i' (resembles 1, a binary digit or bit) and 'i' is located in the answer.
The remaining letters 'cruse' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cruise that I've seen before include "Holiday on liner" , "Sail to and fro" , "Sail on a ship" , "journey" , "Ship holiday" .)
