Misinform and stop ship (3,2)
I believe the answer is:
lie to
I believe this clue is a double definition.
'misinform' is the first definition.
(to lie to someone is to misinform them)
'stop ship' is the second definition.
(if a ship 'lies to', it comes to a stop)
'and' is the link.
(Other definitions for lie to that I've seen before include "ship's to show no sign of movement" , "Become stationary (naut.)" , "(Of a ship) come almost to a stop going into the wind" , "See 10 Across" , "Remain motionless" .)
