All aboard, Blockheads! Six months after it was first announced, the NKOTB reality show has a premiere date. Rock This Boat: New Kids on the Block is due to set sail on Wednesday, Jan. 14, 2015 — and Us Weekly has an exclusive sneak peek at the first minute of the eight-episode series.

The Pop (currently TV Guide Network) show spotlights the boy band's famous annual cruises, which are so popular that they have wait lists of thousands. This year, the ship took Blockheads on a five-day journey from New York City to Bermuda.

"Every year, my bandmates and I go on a cruise with 3,000 of our wildest and most adoring fans," NKOTB's Donnie Wahlberg explains. "For the first time ever, we're gonna take you behind the scenes to see what it's like. Three thousand fans, 20 cameras — that equals a whole lot of potential chaos."

Indeed, if the clip above is any indication, things get pretty crazy when the band — made up of Wahlberg, Jordan and Jonathan Knight, Joey McIntyre, and Danny Wood — hits the open waters. Blockheads can see all the action beginning Jan. 14 at 8 p.m., when the show debuts with a one-hour premiere.

If you can't wait until then (and we don't blame you!), there's also a "Meet the Castaways" special set to air on Monday, Nov. 24 at 8 p.m., as well as a December special from ET about the history of the boy band, which rose to fame in the 1980s and '90s with hits like "I'll Be Loving You (Forever)" and "Step by Step."
