The couple holding the boat up? (6)
I believe the answer is:
davits
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for davits that I've seen before include "Cranes for lifting boats" , "Curved devices used as cranes on a ship" , "Curved devices used as cranes on a ships" , "Ship's boat cranes" .)
