Ahoy, mateys! Below Deck returns this September, and Season 4 isn't going to be an easy ride. "I always get excited about seeing how the crew are going to mesh. You hope for the best — but you plan for the worst," Captain Lee Rosbach says about the team he's assembled for charters throughout the British Virgin Islands. And from our peek at the first trailer, it definitely looks like it's going to be a mix of highs and lows aboard the 154-foot mega yacht Valor. Captain Lee will be joined by familiar faces in chief stew Kate Chastain and chef Ben Robinson (who recently sailed on Below Deck Mediterranean). Below Deck Season 2's Kelley Johnson is also back, and this year he's been promoted to bosun. "For me, it's definitely about redemption," Kelley says of returning to Captian Lee's crew. Joining the vets are Trevor Walker (senior deckhand), Nico Scholly (second deckhand), Lauren Burchell (deckhand), Emily Warburton-Adams (second stew), and Sierra Storm (third stew).

In addition to trying to please their charter guests this season, there's quite a lot of romance on the ship. "Love is in the air and it's spreading among the crew," Kate notes. But not everyone is excited to be working in such close quarters, as longtime pals and co-workers Ben and Kate seem to be at odds ("I don't like working with you anymore," Ben tells Kate).

Below Deck Season 4 premieres at September 6 at 9/8c. Check out a full tease above, and prepare for the new season with some throwback photos of your favorite yachties, below.
