Nick snapped some pics of his big bro as Joe jumped off the top level of the boat into the water! Nick opted to dive in from the lower level.
Joe was also seen riding a jet ski, and the group made sure to enjoy their cold drinks while working on their tans.
Oh, and Nick brought along his weights so he could get some lunges in.
Head to our gallery to see all the pics!
