Passengers aboard the Radiance of the Seas got a much more dramatic evening than expected after the ship suddenly lost power while sailing through the Gulf of Mexico late Saturday night.
What began as a normal return voyage from Cozumel quickly turned unsettling when lights reportedly shut off across parts of the ship, engines stopped running, and the vessel temporarily drifted in darkness at sea.
And honestly, there are few things more unsettling on a cruise than suddenly realizing a massive ship has gone completely quiet in the middle of the ocean.
Guests Say the Ship Suddenly Went Dark
Passengers onboard started posting updates online around 10:00 p.m. local time on May 16, 2026, describing a sudden power outage aboard the ship.
According to multiple guests, public areas instantly lost lighting while the vessel appeared to stop moving entirely for a short period.
Passengers Reportedly Experienced:
- Sudden loss of lighting.
- Engines shutting down.
- Public spaces are going dark.
- Temporary drifting at sea.
- Multiple power interruptions.
One guest onboard wrote online that the ship’s power had gone out completely and the engines were no longer operating.
Other passengers tracking the ship using cruise tracking apps noticed the vessel slowing dramatically shortly after the outage occurred.
And honestly, when a cruise ship suddenly stops moving in open water, passengers immediately start wondering whether something much more serious is happening behind the scenes.
Some Guests Described “Pitch Black” Conditions
Several passengers onboard described portions of the ship becoming extremely dark after the outage.
Cruise ships normally operate with massive amounts of lighting across public decks, restaurants, hallways, bars, and entertainment areas — so when those lights suddenly disappear, even experienced cruisers notice immediately.
Guests Said They Saw:
- Hallways with minimal lighting.
- Darkened public areas.
- Guests using phone flashlights.
- Temporary confusion onboard.
- Crew members assisting passengers.
Despite the unsettling situation, some guests later joked online that the unexpected blackout briefly turned into an “acoustic dance party” as passengers used phone flashlights and improvised entertainment while waiting for updates.
That’s honestly a very cruise passenger reaction — turning a stressful moment into a temporary party while everyone waits for answers.
The Ship Apparently Lost Power More Than Once
According to several passengers posting updates throughout the night, power may not have fully stabilized immediately after the first outage.
Some guests claimed the ship briefly regained power before experiencing another interruption shortly afterward.
Guests Reported:
- Initial blackout.
- Temporary restoration.
- Additional power interruption.
- Eventual stabilization later in the evening.
Within roughly an hour, passengers said the captain announced that propulsion had been restored and the ship would continue sailing back toward Tampa.
Cruise tracking data later showed the vessel moving normally again through the Gulf of Mexico at around 17 knots.
Royal Caribbean Hasn’t Explained What Happened Yet
So far, Royal Caribbean International has not publicly confirmed what caused the temporary power outage aboard the ship.
At this stage, passengers are mostly relying on onboard announcements and social media updates from fellow cruisers.
Questions Still Unanswered Include:
- What caused the blackout?
- Why did propulsion temporarily stop?
- Whether backup systems are activated normally.
- If any technical repairs were required.
Importantly, there have been no reports of injuries connected to the outage itself.
And by the following morning, several guests onboard said the ship appeared to be operating normally again without additional problems overnight.
The Ship Had Already Experienced a Strange Evening Before the Blackout
Interestingly, passengers say the power outage wasn’t even the first unusual event of the evening.
Before the blackout occurred, guests reportedly noticed Radiance of the Seas unexpectedly turning back toward Cozumel shortly after initially departing the port.
According to passengers onboard, the ship returned because of a reported medical emergency involving another guest.
Passengers Claimed the Situation Involved:
- A medical emergency onboard.
- A return to Cozumel after departure.
- Guests disembarking the ship.
- An older passenger needing assistance.
One passenger online claimed an older woman and her husband left the vessel during the emergency stop, though Royal Caribbean has not officially confirmed those details publicly.
After departing Cozumel for the second time, passengers say the blackout occurred roughly an hour later.
And honestly, after already dealing with an unexpected return to port, the sudden power outage probably made the evening feel even more chaotic for passengers onboard.
