Meek Mill has Huge Yacht Party with His New Girlfriend (PHOTO GALLERY)

Meek Mill loaded up a yacht with 2 decks worth of hot chicks and other partygoers ... and his new gf was there too.

Meek's huge group of party pals sipped drinks and turnt up with a DJ spinning music on board. Meek's new chick, Vanessa, brought along some girlfriends as well.

Vanessa -- who also goes by Nessa Colombiana -- has been hanging with the rapper for over a month and the 2 hung out in Miami low key during Memorial Day weekend.
