Navigator's tragic end on a wrecked boat (5)

I believe the answer is:

cabot

I'm a little stuck... Click here to teach me more about this clue!

'navigator's' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?

'tragic end on a wrecked boat' is the wordplay.
'end' says to take the final letters.
'on' is a charade indicator (letters next to each other).
'a wrecked' indicates an anagram.
The last letter of 'tragic' is 'c'.
'boat' anagrammed gives 'abot'.
'c'+'abot'='CABOT'

Can you help me to learn more?
