Whiting, 27, is one of the Airlie Birds most popular players due to his work on and off the pitch.
The versatile Whiting has been impressive as a loose forward under Peter Gentle. Both player and coach are delighted with the new contract.
Whiting was quoted on hullfc.com as saying: “There is a real belief around the club that we are now going places, so I definitely want to be a part of that. It was a very simple decision for me to make.”
Gentle said: “He understands the game and his role, he gives 110% every week and that is probably why he is so adaptable and can cover many roles for us. There is no-one more deserving of a new deal with the club.”
Whiting has so far made over 180 appearances for the club, scoring 58 tries.
