Below Deck Sailing Yacht - Season 4

Back on board Parsifal III in Sardinia, Italy, with his heads of departments returning for another season, Capt. Glenn is poised for his smoothest sail yet… until he isn't. Daisy comes back with a clear goal, ready to prove to everyone she knows what she's doing as a chief stew. Newly single for the first time in years, Chief Engineer Colin is determined to avoid a boat romance. With a new junior crew on board joining the HODs, a charter starting in 24 hours and an engine that surprisingly won't start, everyone is wondering: Where is Gary? And will Parsifal III ever be able to leave the dock?

Capt. Glenn is hopeful for Colin's plan to "rebuild" the engine, but with his first mate still out and his engineer indisposed, Capt. Glenn cracks under pressure to impress the docked guests. While joining the guests for dinner, Capt. Glenn notices Chef Ileisha's inadequate portion sizes and slow timings. To add insult to injury, the guests tell Capt. Glenn this is the "worst trip of their lifetime" and specifically blame Daisy's lack of service. Capt. Glenn worries that his interior team isn't prepared and begins to question whether this charter season will be smooth sailing.

Capt. Glenn finally wakes up to some good news: His first mate is finally joining the crew, helping to relieve some stress before the anticipated sea trial. With a rough first charter to start the season, the crew is crossing its fingers the engine fixes can get them off the dock. For the first time in Below Deck history, the entire crew is invited to join the guests for dinner, and Chef Ileisha has to change her menu last minute. Gary's return means he has a lot of catching up to do in the romance department as he attempts to get to know the ladies on board.

Capt. Glenn remains committed to improving the guest experience by insisting a stew go on all excursions. Daisy is frustrated after learning she's a stew down while the deck team goofed off on the eFoils. Chef Ileisha's perfectionism is thrown off when she faces her greatest fear in the galley and enlists Colin's help. Gary claims his territory as First Mate both with the ladies and on deck as he sets his eyes on Mads knowing his deckhands are interested in the same girl.

Daisy is overwhelmed with the high-maintenance guests and struggles to ask for help, so a request from Gary sends her over the edge. When a guest injury occurs on the water toys, Capt. Glenn goes into high alert to make sure the charter is still successful. Since a few of the guests are at the hospital, Chef Ileisha struggles to keep up with the changing mealtimes.

In an effort to turn the charter around, Capt. Glenn takes the guests on an epic sail. Lucy makes a grave mistake with a charter guest's garment. After Chef Ileisha continues to leave the guests waiting too long between courses, Capt. Glenn gives her honest feedback in the tip meeting that pushes Daisy's defensive buttons. Colin defends Capt. Glenn's comments as feedback and not critique, which only heightens Daisy's frustrations.

Another engine issue emerges, forcing Capt. Glenn to modify the plan and keep the returning guests entertained. With all the uncertainty going on in the engine room, Capt. Glenn takes control and points out the crew's mistakes. Daisy and Colin make up after their fight as their relationship grows stronger. Daisy confronts Gary about Mads and claims he's playing his usual games. Tired of the drama, Chase plans a night of drunk Twister and hosts a surprising yoga session.

After Chase confides in Gary about Alex's lackluster work ethic, Chase's trust is broken when Gary tells Alex about their conversation. The crew pull off talent show No. 2 for the returning guests and surprise themselves with their interesting skills. Chase has a little too much to drink as he upsets some of the crew, pushing Lucy to lose it and her chair at dinner. Daisy and Colin get closer than ever as they share an unexpected kiss.

Capt. Glenn dresses up for the guests' theme night, pleasing them at dinner. He hopes his participation helps correct a "jewelry theft" hiccup and is on top of his crew to make sure these women have the best trip of their lives. Unbeknownst to Mads, Gary struggles with how he's actually feeling about Colin and Daisy hooking up for the first time. Colin learns that Gary has broken "bro code" once again.

The crew has the day off, and even Capt. Glenn recharges by enjoying Parsifal III all to himself and riding the eFoil. Colin saves the day by clearing the clogged toilets but gets jammed up when his honest opinion strikes a chord that sends Chef Ileisha into an emotional fury. Gary notices Daisy and Colin getting closer and decides to make a confession to Daisy.

Caught in an uncomfortable situation, Daisy doesn't know where her and Colin stand anymore after keeping a massive secret from him. Determined to prove Colin wrong, Chef Ileisha picks herself up just to be knocked back down when she burns her hand cooking during an unexpected sail. Gary vocalizes his feelings to Mads, all while confessing to her that he and Daisy have hooked up in the past. Colin feels betrayed by his two best friends on the boat and turns to his sister for advice on how to move forward, if at all.

Capt. Glenn notices the standards are slipping on Parsifal lll, as the crew is exhausted with the mid-season blues. Distraught that Colin and Gary aren't speaking, Daisy takes initiative and forces them to hash out their problems. Gary's confusing behavior has Mads confessing her feelings to Alex. Colin tries to forgive Daisy's indiscretions, but she adds insult to injury after she drunkenly confuses him for Gary. On charter, after anchoring in their first destination, Parsifal lll nearly drags into a neighboring boat.

Capt. Glenn notices the crew is slipping on service when a guest is injured and the interior doesn't hear the walkie call, forcing Capt. Glenn to up the guest maintenance standards onboard. After Alex and Mads confess their feelings from the start, Mads is torn between Alex and Gary. Shaken after a close T-bone with a nearby boat, Gary is confused when his advances to Mads aren't being reciprocated.

Capt. Glenn reprimands the crew, as recent slipups are directly affecting communication and morale. Daisy breaks down when she's proven wrong about the walkies not working. Chef Ileisha is determined to prove she can complete a 10-course dinner. On the crew night out, Daisy navigates Colin, Gary and her sister, Bonnie. Mads unintentionally embarrasses Gary in front of the crew.

Capt. Glenn is proud of the crew for knocking out a pride charter but has to deliver bad news - no turnover day before the final charter. After Gary learns of Mads' three-way kiss, he starts flirting more with Daisy, leading Colin to voice his concerns. Colin stirs the pot by throwing a gossip grenade that forces Gary to confront Mads in a way that has Lucy speechless.

Capt. Glenn threatens to kick one of the "throuple" charter guests off Parsifal during a drunken guest fight. Mads receives a wake-up call that prompts her to dismiss Gary's apology attempt and more seriously consider Alex, leaving Gary with a stomach full of regret. Unhappy with Gary, Alex and Colin decide to follow their hearts instead.

Proud of his team's accomplishments during the final sail, Capt. Glenn believes his tough love made them all stronger. The crew celebrates their final night out, and Daisy and Colin try to soak up every moment of it. Following tearless goodbyes, Capt. Glenn and Gary stay onboard Parsifal to pick up another charter season.
