Patrick Schwarzenegger may have four years on his brother.
But the 19-year-old model was no match for Christopher, 15, as they got competitive during a game of ball in the Hawaii sea on Wednesday.
Christopher made light work of his brother, dunking him under the waves with apparent ease as a they fought each other in a bid to catch the ball.
But Patrick may have had the ultimate bragging rights on the day, for after their playful interlude he had a hot and heavy smooching session with his girlfriend in the water.
But this came after a touching scene of brotherly affection and rivalry they laughed and whooped while splashing around in the water.
Patrick has spent the last few days soaking up the sun in Miami and enjoying a few wild nights out with his pals at the city's Ultra Music Festival.
He is now recuperating from his break with the boys on a family trip to Hawaii.
Playful: The siblings appeared to be having a great time as they got sporty in the ocean
Making a splash: The twosome are currently on a family holiday on the picturesque island of Maui
Earlier he was seen grabbing a paddle-board and making his way into the water.
The model showed off his buff beach body - no doubt inherited from his former bodybuilder father - in a pair of multicoloured striped swim shorts.
Navigating his way around the ocean, the teenager seemed to be quite the expert when it came to mastering the art of the relaxing watersport.
