Below Deck Down Underseason 3's Tzarina Mace-Ralph has been struggling throughout the current season of the series, and with some major signs pointing toward her being done finished with the show, it's possible this could be her last season. Tzarina, who first appeared on Below Deck Down Under season 2, has been working hard throughout her time aboard Captain Jason Chambers' superyacht crew. While this season hasn't been particularly easy for Tzarina, Below Deck Down Under season 3 has presented the chef with a whole new set of challenges. Tzarina's time aboard superyacht Katina hasn't been easy at all.
