The age of wrecked boats? (5)
I believe the answer is:
sabot
'the age' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'wrecked boats?' is the wordplay.
'wrecked' indicates anagramming the letters.
'boats' with letters rearranged gives 'SABOT'.
'of' is the link.
Can you help me to learn more?
(Other definitions for sabot that I've seen before include "Wooden clog" , "This from last" , "Wooden-soled 13 down" , "French clog" , "Boast (anag) - shoe" .)
