Though good, he makes a bad start in a faulty boat (5)
I believe the answer is:
abbot
'though good he' is the definition.
'Abbot' can be an answer for 'he'. I am unsure of the 'though good' bit.
'a bad start in a faulty boat' is the wordplay.
'start' suggests taking the first letters.
'in' means one lot of letters goes inside another.
'a faulty' is an anagram indicator.
The initial letter of 'bad' is 'b'.
'boat' with letters rearranged gives 'abot'.
'b' inserted within 'abot' is 'ABBOT'.
'makes' is the link.
Can you help me to learn more?
(Other definitions for abbot that I've seen before include "Monks' superior" , "Head of monastery" , "Religious leader" , "Religious man" , "Head of a community of monks" .)
