Historic vessel just about wrecked (1-4)
I believe the answer is:
u-boat
'historic vessel' is the definition.
'u boat' can be an answer for 'vessel' (I've seen this before). I am not sure about the 'historic' bit.
'about wrecked' is the wordplay.
'wrecked' indicates an anagram.
'about' anagrammed gives 'U-BOAT'.
'just' acts as a link.
Can you help me to learn more?
(Other definitions for u-boat that I've seen before include "German World War One or World War Two submarine" , "Submersible warship armed with torpedoes" , "German submarine of WW2" , "German WW 2 sub" , "Take pool exercise" .)
