Though Kate Chastain left Below Deck after Season 7 wrapped, she is somewhat still the face of Below Deck. That honor arguably belongs to Captain Lee Rosbach. Of course Kate worked along side Captain Lee for five seasons, and her longevity in the industry makes her opinion about all things yachting a reliable one.
And the former Bravo Chat Room host certainly has a unique style when it comes to delivering her opinion. Her dry sense of humor became a staple with viewers. So of course when something of interest happens on any show in the franchise, Kate will give her opinion.
