Vessel arrives on land with it (9)
I believe the answer is:
lightship
'vessel' is the definition.
(lightship is a kind of vessel)
'arrives on land with it' is the wordplay.
'arrives' becomes 's' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'on' is a charade indicator (letters next to each other).
'land' becomes 'light' (lighting is a kind of landing).
'with it' becomes 'hip' (I've seen this before).
's' after 'light' is 'lights'.
'lights'+'hip'='LIGHTSHIP'
Can you help me to learn more?
(Other definitions for lightship that I've seen before include "could reveal a watery problem" , "which attracts the attention of sailors" , "Guiding vessel sounds as if it has no cargo" , "Navigational aid" , "vessel anchored near rocks?" .)
