Tricky current making ride uncomfortable in keel (4-3)
I believe the answer is:
tide-rip
'tricky current' is the definition.
The definition suggests a singular noun which matches the answer.
'ride uncomfortable in keel' is the wordplay.
I cannot really see how this works, but
an anagram of 'ride' is 'ider' which is within the answer.
The remaining letters 'tip' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'making' acts as a link.
Can you help me to learn more?
(Another definition for tide-rip that I've seen is " Area of rough sea where currents meet".)
