As an anchor may be? Not at home, we hear (6)

I believe the answer is:
aweigh
'as an anchor may be?' is the definition.
I can't judge whether this definition defines the answer.
'not at home we hear' is the wordplay.
'not at home' becomes 'away' (I've seen this before).
'we hear' indicates a 'sounds like' (homophone) clue.
'away' sounds like 'AWEIGH'.
Can you help me to learn more?
(Other definitions for aweigh that I've seen before include "Of anchor, hanging just clear of sea bottom" , "Hanging like anchors" , "Off the bed (as anchor)" , "anchor might be" , "Of anchor, hanging just clear of sea-bed" .)
