There’s a boatload of secrets.

A cruise worker has revealed some little-known facts about ships in a viral video that could rock your boat.

“If passengers knew what really happens behind the scenes, they’d never look at cruises the same way,” the woman — who goes by @your.beauty.dose on TikTok — captioned the clip that’s been viewed 8.3 million times.

The employee began by revealing a morbid factoid: all cruise ships have hidden morgues below deck that are used “more often than you’d think.” When passengers die at sea, their bodies are kept until the boat docks at the next port.

Not everything is so macabre, however.

Some people are cruising for a good time, hoping to find “like-minded” people, the cruise worker revealed in another viral video.

The ocean explorer also revealed that “Pineapple Rooms” — those with the juicy snack upside-down on their doors — are not adorned “just for decoration.”

“It’s a coded invitation for guests looking for a different kind of fun,” she said, hinting that the flipped fruit is often used to signal swingers or a person’s openness to meeting other couples for sexy time.

But it’s not always smooth sailing.

“Break the rules onboard, and you might end up in the cruise ship jail,” the worker said, describing the seabound slammer as a “tiny locked room where unruly passengers stay until the ship reaches port.”

She also had a perhaps less-than-appetizing secret about the copious amounts of food that constantly flow on ships, revealing that leftover food from one meal often gets repurposed into another dish.

“That soup you are eating? It might’ve started as last night’s side dish,” she said.

In her most recent video, the cruise ship worker rehashed some of the same reveals, along with some spooky, new information.

“Every year, a few passengers mysteriously disappear. No one talks about it, but it happens,” she claimed.

Cruising has become increasingly popular and boujee in recent years — a major line recently ranked alongside the world’s top luxury hotels on an elite new travel list.

But some subpar ships are sketching people out.

On the Centers for Disease Control and Prevention’s Vessel Sanitation Program review, scoring 85 out of 100 is considered a failure, per Business Insider.

Of the over 100 ships inspected, the average score was about 95.9 — and 27 ships received a perfect 100. Two of the ships initially failed, but passed in later follow-up reviews.

However, nine of the ships didn’t break the 90 mark. They were:

1. Hanseatic Inspiration: Hapag-Lloyd Cruises, scored 89 (inspected Oct. 28; previously received a 62 on Sept. 29)
2. Carnival Elation: Carnival Cruise Line, scored 89 (inspected March 14)
3. Adventure of the Seas: Royal Caribbean International, scored 89 (inspected Jan. 23)
4. National Geographic Sea Bird: Lindblad Expeditions, scored 88 (inspected July 25)
5. Carnival Miracle: Carnival Cruise Line, scored 88 (inspected April 21)
6. MSC Magnifica: MSC Cruises, scored 86 (inspected May 17)
7. Evrima: Ritz-Carlton Yacht Collection, scored 86 (inspected Feb. 9)
8. Carnival Breeze: Carnival Cruise Line, scored 86 (inspected March 21)
9. Caribbean Princess: Princess Cruises, scored 86 (inspected March 20)
