A towrope failing to secure bulkhead of pleasure craft (9)
I believe the answer is:
powerboat
'pleasure craft' is the definition.
'powerboat' can be an answer for 'craft' (powerboat is a kind of craft). I'm unsure of the 'pleasure' bit.
'a towrope failing to secure bulkhead' is the wordplay.
'failing' indicates an anagram.
'to secure' means one lot of letters goes inside another (inserted letters are secured inside).
'bulkhead' becomes 'b' (head letter of 'bulk').
'a'+'towrope'='atowrope'
'atowrope' with letters rearranged gives 'poweroat'.
'poweroat' placed around 'b' is 'POWERBOAT'.
'of' is the link.
Can you help me to learn more?
(Other definitions for powerboat that I've seen before include "Fast motor craft" , "One quick on the surface" , "Fast water vessel" , "sporting vessel" , "Fast vessel for racing or leisure" .)
