Consisting of five 60-minute episodes, the new series will see 12 celebrities test out their sea legs as they compete in one of the "toughest" challenge-based shows ever filmed on land and sea.
They'll be faced with the waves and wind as they race on the water, while also negotiating some of the most daunting cliffs and gorges of Britain's shoreline for the land-based challenges.
Alongside Lucy and Jack, the other celebrities taking part include I'm a Celebrity's Fleur East, Red Dwarf star Craig Charles, The Chase's Shaun Wallace, Pussycat Dolls member Kimberly Wyatt, model and presenter Jodie Kidd, and YouTuber Joe Weller.
Presenter and Olympic gold medalist Denise Lewis OBE, I'm a Celebrity and Emmerdale star Adam Thomas, Olympic, World and European Champion cyclist Victoria Pendleton CBE, and politician Tom Watson also join the show.
Flintoff said of the show: "I'm thrilled to be hosting this brand new show for ITV. It sounds like it's going to be a huge challenge for the twelve rowers so I'm pleased that I'll be spending most of my time on dry land... hopefully!
"It should be a great watch for everyone at home and I can't wait to get started.”
AJ Odudu added: "This is going to be a great show, with an epic line-up. Such a brilliant mix of personalities and challenges which always makes for good telly.
"I personally cannot wait to get going - especially filming with the legend that is Freddie Flintoff. We’re going to have so much fun! Bring it on!"
Don't Rock the Boat will air on ITV later this year.
