Kate Chastain — Chief Stewardess and Television Personality
Rise to Fame on Below Deck
Kate joined Below Deck in its second season in 2014, stepping into the role of chief stewardess. Over the course of six seasons, she became one of the most memorable cast members in the franchise. Viewers loved her for her wit, her steady leadership below deck, and her willingness to speak her mind on camera.
She left the show after Season 7 in 2020, closing out a run that helped define the early years of the Below Deck franchise. Her impact still shows up in fan comments today. One viewer wrote in 2026 that watching the show without her feels like cheating, a sign of how much she shaped the series for longtime fans.
As chief stewardess, Kate managed the interior team, oversaw guest service, and handled the day-to-day pressure of running a charter yacht smoothly. Her role put her at the centre of many of the show’s biggest moments, from guest complaints to crew conflicts. That mix of leadership and honesty is a big part of why fans still bring her name up years after her final episode aired.
The Traitors and House of Villains
After stepping away from yachting life on screen, Kate found a new home in competition television. She joined Season 1 of Peacock’s The Traitors in 2023, playing as a Faithful and finishing in fifth place. She came back for Season 2 as a mid-season addition, was recruited as a Traitor, and was banished near the end of the game.
In 2026, Kate joined House of Villains Season 3, a competition show hosted by Joel McHale. She placed third, adding another strong finish to her growing list of reality competition credits.
Hosting and Other TV Appearances
Kate has built a career well beyond her original yachting role. In 2020, she served as host and executive producer of Bravo’s digital talk series Bravo’s Chat Room. She also appeared on Below Deck Galley Talk and co-hosted Couch Talk with Captain Lee and Kate in 2023 alongside her former co-star, Captain Lee Rosbach.
Her other television credits include appearances on Watch What Happens Live with Andy Cohen and The Traitors: Postmortem in 2024. Together, these roles show how Kate turned a single reality show role into a lasting media career.

Kate went on to attend the University of Central Florida, where she studied communications. During this time, she developed a strong interest in hospitality and customer service, skills that would later shape her career on the water. After graduating, she entered the yachting industry, starting as a laundry stewardess and working her way up to chief stewardess on luxury yachts. This hands-on experience in the maritime world directly led to her casting on Below Deck.
