Some boats, eastbound away from the land (2,3)
I believe the answer is:
at sea
'land' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'some boats eastbound away' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'AT SEA' can be found hidden inside 'boats eastbound away'.
'from the' is the link.
Can you help me to learn more?
(Other definitions for at sea that I've seen before include "Voyaging" , "Disorganised; bewildered" , "Perplexed" , "Where a packet might be" , "stumped" .)
