Functioning doubles borne by a hotel-island that appears in Genesis (5,3)
I believe the answer is:
noahs ark
'functioning doubles borne' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'a hotel-island that appears in genesis' is the wordplay.
I cannot really see how this works, but
'a' is found in the answer.
'hotel' could be 'h' (phonetic alphabet) and 'h' is present in the answer.
'island' could be 'sark' (I've seen this before) and 'sark' is found within the answer.
The remaining letters 'no' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'by' acts as a link.
Can you help me to learn more?
(Other definitions for noahs ark that I've seen before include "Rescue vessel" , "Biblical ship" , "Old vessel" , "Biblical transport" , "animal transport" .)
