In an amazing clip shared on Instagram, diver Cesilie Carlton leaps from a platform high above a cruise ship pool - performing jaw-dropping somersaults before hitting the water below.
Sydney Brown, a fellow cruise ship diver who filmed the clip says the pool is the deepest of any cruise liner, though rough seas can mean they have to cancel shows.
‘If the ship is moving from side to side, the water in the pool can spill out,’ she explains.
Cesilie's Instagram also features dive videos - including this one which shows the true dizzying heights that she is diving from.
Sydney Brown has also shared incredible clips of her performances on board the cruise liner.
