Kim Kardashian West is teaching her kids how to live it up in Miami ... which should always include some time spent on a luxury sea vessel.
KKW brought her oldest children -- North and Saint -- onboard Miami mogul David Grutman's yacht Thursday ... and had her finest hot pink, skin-tight Chanel catsuit on to chase 'em around.
North matched her mom with some pink shorts, and Saint looked absolutely adorable rocking a captain's hat.
Also on the yacht were family friends Jonathan Cheban, Larsa Pippen and her daughter Sophia.
Btw ... Kim knows how to do an encore when it comes to her bright and tight Miami outfits. We see you, girl.
