The azure waters and ancient ruins of Athens, Greece set the scene as Capt. Sandy returns to steer her team through a season brimming with fresh and formidable challenges. Between eccentric guests, an abundance of late-night demands that require intervention and a never-before-seen mechanical issue that orders all hands on deck, the crew faces tumultuous waves from the start.       Back on board the 180-foot M/Y Mustique, a series of initial hurdles sets the crew off on the wrong foot. Amidst a saga of delayed provisions, managing a complicated interior department and a medical emergency, Aesha strives to ensure the guests are treated to a five-star service experience. Chef Jono, a self-taught culinary architect, quickly learns he has high expectations to fill to prove his culinary capabilities to the guests. Meanwhile, the deck crew faces its own hurdles and must learn that communication is key in order to successfully get through the season.      This season’s boatmances stir up waves of tension as two crewmates find themselves with their sights set on a mutual love interest causing disruptions among departments. A personal relationship also tests a deckhand’s budding romance, leading them to make a tough decision.       Finally, to round out the season, Capt. Sandy orchestrates the surprise of a lifetime for her partner, Leah, that leaves everyone in tears.
