Partly developed a local craft using one's own manpower (6)
I believe the answer is:
pedalo
'one's own manpower' is the definition.
I can't tell whether this definition defines the answer.
'partly developed a local craft' is the wordplay.
'partly' indicates the answer is hidden within the clue (part of the clue is used).
'PEDALO' is hidden within 'developed a local craft'.
'using' is the link.
Can you help me to learn more?
(Other definitions for pedalo that I've seen before include "Foot-powered pleasure craft" , "Pleasure craft -- old ape (anag)" , "Small foot-powered pleasure boat" , "Paddle boat" , "Boat driven by foot power" .)
