Picture this: it’s a Tuesday night, you’re three episodes deep into Below Deck, and your favorite chief stew, Kate Chastain, just dropped a one-liner so sharp it could slice a lime. You pause the remote, turn to your friend (or your cat), and ask: “Wait, how old is she, anyway?” We’ve all been there. Age feels like a secret code on reality TV, and Kate’s is one we’ve been trying to crack for years.
So, let’s get the main event out of the way: Kate Chastain was born on January 2, 1982. That makes her 43 years old as of 2025. Yes, the same woman who once dragged a hungover deckhand up a spiral staircase while wearing heels is now in her early forties. It’s almost unfair, right? She’s aging like fine wine—or at least like a very expensive bottle of rosé you’d drink on a superyacht.
A Little Backstory, Because You Asked
Before she became the queen of the interior, Kate worked on yachts for over a decade. She started when she was just 21, which means she’s been dealing with rich people’s laundry and drunk guests since before Instagram existed. That’s a lot of stamina. When she joined Below Deck in 2013 for Season 1, she was already 31. You can do the math—it’s not hard, but I’ll wait.
Must Read
What’s wild is that she looks pretty much the same now as she did back then. Maybe it’s the sunscreen. Maybe it’s the sarcasm. I’m leaning heavily toward the sarcasm. It’s a preservative, I swear.
Why Does Her Age Even Matter?
Here’s the thing: Kate’s age is more than a number—it’s part of her brand. She’s not the fresh-faced 24-year-old bosun trying to prove herself. She’s the seasoned vet who has seen it all. She’s the one who can out-drink the guests, out-snark the captain, and still remember where she put the spare toilet paper at 3 AM. That level of expertise? It takes years.
Why Kate Chastain Is The Best Thing About Below Deck – TVovermind
And let’s be honest, age gives her the upper hand in every crew drama. When a 22-year-old stew whines about a hangover, Kate just blinks slowly and says, “Oh honey, I’ve been hungover since 2004.” You can’t argue with that kind of authority. It’s earned, not given.
The Ironic Part: She’s Now “Old” for a Yachtie
Here’s the irony that makes me chuckle: in the yachting world, 43 is practically retirement age. Most crew members are in their mid-twenties, burning out after a few seasons. But Kate? She thrives on being the elder stateswoman. She even joked on social media that she’s the “grandma” of the franchise. And she owns it.
A Great Chief Stew Keeps 'Below Deck' Afloat
I mean, think about it. She left the show after Season 7, but when she pops up on Below Deck Galley Talk, she still looks like she could run a 50-person charter with one hand tied behind her back. Age just doesn’t slow her down—it gives her better stories. Remember when she caught on fire in the galley? That’s a 43-year-old’s battle scar, my friend.
What’s She Doing Now at 43?
Since leaving the show, Kate hasn’t exactly retired. She’s writing books, hosting podcasts, and occasionally roasting fans on Twitter. Oh, and she had a baby! That’s right—in 2022, she became a mom. At 40 years old. Which, frankly, is the most “Kate” thing ever: do something most people consider “late” and make it look effortless.

She also still posts about her love for a good martini and her hatred for folding napkins. Some things never change. And thank goodness for that. If Kate ever stops being petty, the universe will implode.
The Takeaway: Age Is Just a Number (But It’s a Cool Number)
So next time you binge Below Deck, remember: Kate is 43, she’s a mom, she’s a best-selling author, and she can still out-drink you. Probably. She’s not hiding her age because she’s ashamed—she’s just too busy being iconic. And honestly, we should all be so lucky.
Now, go rewatch the season where she threw a guest’s shoe overboard. It hits different when you know she was 35 at the time. Respect.
