A charter group of super-yachties arrives, and the Parsifal crew is anxious about being judged by their peers. But as the guests get boozed up, the Parsifal crew contemplates getting down, and Captain Glenn keeps a worried eye on his party-hardy team. After the charter, the final night out takes place at a picturesque castle, where Daisy reveals a secret that sets fireworks off in all directions. Back on the boat, the crew forgoes fighting for festivities, as Gary turns the hot tub into a wet and wild bubble bash. Most of the crew says their good-byes, but Natasha, Gary, Alli, and Sydney stay aboard to help Glenn with an ocean crossing. The drama doesn't stop even though the season is over.
