Visibly embarrassed to visit capsized registered vessel (7)
I believe the answer is:
dredger
'vessel' is the definition.
(dredger is a kind of vessel)
'visibly embarrassed to visit capsized registered' is the wordplay.
'visibly embarrassed' becomes 'red' (someone may blush or go red when embarrassed).
'to visit' is an insertion indicator.
'capsized' says the letters should be written in reverse.
'registered' becomes 'regd' (I am not sure about this - if you are sure you should believe this answer much more).
'regd' written backwards gives 'dger'.
'red' placed inside 'dger' is 'DREDGER'.
Can you help me to learn more?
(Other definitions for dredger that I've seen before include "One cleaning up bed" , "It clears beds" , "Boat used in scooping out mud, etc., from the bottom of a river" , "ship" , "Vessel for dragging the bottom" .)
