Cruz Beckham joined his famous father on board the family's $5 superyacht during their sun-soaked Miami getaway on Friday.

The 17-year-old son of David and Victoria Beckham, soaked up the sun in a white vest and printed Thrasher shorts.

He completed the look with a gold chain and carried a blue baseball cap as he made his way along the deck. 

Meanwhile footballer David, 47,  who is also father to Brooklyn, 23,  Romeo, 21, and 11-year-old daughter Harper, kept cool in the shade. 

Donning a dark T-shirt and beige shorts he could be seen sporting a pink baseball cap backwards. 

David named his yacht after his iconic shirt number he wore for six years while playing for Manchester United, while he also wore the number seven for international games for England.

Seven also has a special meaning for the David and Victoria as it is also the middle name of their daughter Harper.

The craft can accommodate up to 10 guests in five staterooms, with four crew members on board ready to serve the famous family's every need.

The yacht has a cruising speed of 20 knots and goes up to a top speed of 30 knots, while it can travel a distance of 300 nautical miles without the need to refuel.

The stunning vessel boasts an extended swim platform, beach deck and has two engines which generate 2,400 horsepower each.

It comes after David and daughter Harper enjoyed a family pizza night with BFF Tom Brady and his family on Thursday - as the NFL star continues to move on from his divorce from Gisele Bundchen.

David looked in good spirits as the Beckham and the Brady brood joined forces at Miami Slice pizzeria for a night of pizza making.

Sharing a snap of himself, Harper, Tom alongside daughter Vivian, 10, the England legend wrote: 'Daddy's and there [sic] daughters'.
