For Jay-Z and Beyonce ... the best kinda family time is maritime, and even their 1-year-old twins are already soaking up the luxury yacht lifestyle in Italy.
The Carter clan anchored off the Amalfi Coast Friday. All their kiddos were there too ... Blue Ivy and Sir and Rumi, who mom and dad took turns juggling on deck of the huge ship.
Bey and Jay got in some QT by themselves too ... chilling on a smaller vessel that took them to and from shore, while Beyonce snapped some pics.
Whatever floats their boat.
