Few things disappoint cruise passengers more than waking up on port day, opening the curtains, and realizing the destination they’ve been looking forward to is no longer on the schedule.
That’s exactly what happened aboard Norwegian Sun this week as guests sailing through the Baltic Sea learned their planned stop in Sweden would not happen after the ship experienced propulsion-related problems during the voyage.
While the cruise itself continued and passengers still visited most of the itinerary’s destinations, the unexpected cancellation meant travelers lost one of the cruise’s most anticipated ports near the end of the sailing.
For guests who had booked Stockholm excursions, sightseeing tours, or independent plans, the news came as an unwelcome surprise.
What Happened Aboard Norwegian Sun?

The issue surfaced during Norwegian Sun’s current nine-night Baltic itinerary, which departed Copenhagen, Denmark, on June 15.
Up until that point, the cruise had been progressing smoothly.
Guests had already visited several major Northern European destinations, and many passengers described the sailing positively.
Then came the unexpected update.
Passengers onboard began sharing reports that the ship was experiencing propulsion difficulties, making it impossible to maintain normal operating speeds.
One guest posting online explained that the vessel would be skipping its scheduled June 22 call to Nynashamn, Sweden, which serves as a gateway for visitors heading into Stockholm.
To make matters worse, the weather was reportedly beautiful that day.
As many cruisers know, missing a port is frustrating under any circumstances, but it’s even harder when conditions are perfect for sightseeing.
The Port That Was Lost
The cancelled stop was:
- Nynashamn, Sweden.
- Scheduled for June 22, 2026.
- Main access point for Stockholm excursions.
- One of the final ports on the itinerary.
For many passengers, Stockholm would have been one of the highlights of the Baltic cruise.
Known for its waterfront setting, historic Gamla Stan district, museums, and Scandinavian charm, the city is often among the most anticipated destinations on Northern Europe itineraries.
Unfortunately, propulsion limitations made the visit impossible.
Guests Reported the Ship Moving Slowly
Passengers onboard quickly noticed something wasn’t quite right.
Several guests reported that the ship appeared to be moving unusually slowly following the cancellation.
One traveler even commented that it looked as though the vessel was barely moving at times while making its way toward Estonia.
Of course, cruise ships can still operate safely even when experiencing partial propulsion issues.
In many cases, ships are able to continue sailing using reduced power while engineers work behind the scenes to diagnose and repair the problem.
That’s exactly what appears to have happened here.
Although the ship lost one port call, the voyage itself remained operational.
The Good News: The Rest of the Cruise Continued
Despite the propulsion problem, Norwegian Sun wasn’t forced to abandon the remainder of its itinerary.
Before the Sweden cancellation, the ship had already completed visits to:
- Oslo, Norway
- Warnemunde-Rostock, Germany
- Gdynia-Gdansk, Poland
- Klaipeda, Lithuania
- Riga, Latvia
Even better for guests, the ship successfully completed its scheduled visit to Tallinn, Estonia, on June 23.
According to ship tracking information, Norwegian Sun arrived and departed Tallinn as planned before beginning the short journey toward Helsinki, Finland.
That meant passengers still enjoyed the majority of the Baltic itinerary despite losing Stockholm.
Why the Slow Speed Isn’t Necessarily a Concern

Some passengers noticed that Norwegian Sun was sailing at only about seven knots following the incident.
At first glance, that sounds alarming. Most cruise ships typically operate much faster than that.
However, geography plays an important role here.
Tallinn and Helsinki sit relatively close to one another across the Gulf of Finland, with roughly 40 nautical miles separating the two cities.
Because of that short distance, Norwegian Sun didn’t need to travel at full speed to arrive on time.
As a result, the vessel was still expected to reach Helsinki as scheduled for passenger disembarkation on June 24.
Current Situation
At the time of reporting:
| Status | Situation |
|---|---|
| Stockholm Visit | Cancelled |
| Tallinn Visit | Completed |
| Helsinki Arrival | Expected on time |
| Passenger Safety | Not impacted |
| Next Cruise | Currently unchanged |
For guests currently onboard, that means the voyage should still conclude according to schedule despite the missed stop.
Will the Next Cruise Be Affected?
That’s the question many future passengers are asking.
At this stage, Norwegian Cruise Line has not announced any itinerary changes for the ship’s next sailing, which begins on June 24.
The upcoming cruise is essentially the reverse of the current itinerary and will sail from Helsinki back to Copenhagen over nine nights.
So far:
- No cancellations have been announced.
- No ports have been modified.
- No delays have been reported.
- No repair-related schedule changes have been published.
Of course, that could change if engineers determine additional work is needed.
Cruise lines typically wait until they have a clear understanding of a technical issue before making any public decisions about future itineraries.
Engineers May Still Be Working on the Problem
One thing that remains unclear is the exact nature of the propulsion issue.
Norwegian Cruise Line has not publicly disclosed what component was affected or what caused the reduction in performance.
That’s not unusual.
Technical issues can range from relatively minor software or electrical problems to more complex mechanical repairs.
In many cases, onboard engineering teams are able to troubleshoot and resolve problems without taking a ship out of service.
Cruise passengers often never even realize repairs are happening behind the scenes.
Depending on the issue, engineers may:
- Perform diagnostics while at sea.
- Complete maintenance during port calls.
- Replace components during overnight operations.
- Schedule larger repairs during future dry docks.
Until Norwegian provides additional information, the full scope of the issue remains unknown.
Why Propulsion Problems Seem to Be Making Headlines

If you’ve been following cruise news recently, Norwegian Sun isn’t the first ship to experience propulsion-related challenges.
Over the past month alone, several well-known vessels have dealt with similar situations, including:
- Norwegian Bliss.
- Royal Caribbean’s Allure of the Seas.
- Holland America Line’s Zaandam.
That has led some cruise fans to wonder whether propulsion problems are becoming more common.
The reality is a little more complicated.
Thousands of cruise voyages operate successfully every year without any significant technical issues.
Because ships run continuously for months at a time and travel thousands of miles between maintenance periods, occasional mechanical problems are simply part of operating large vessels.
When a ship completes a voyage without issues, it rarely becomes news.
When a ship misses a port, however, it attracts attention very quickly.
Norwegian Sun Has a Strong Reliability Record
While Norwegian Sun isn’t one of Norwegian Cruise Line’s newest ships, she has generally maintained a solid operational history.
The vessel entered service in 2001 and continues to sail a variety of itineraries around the world.
Norwegian has also invested in keeping the ship updated through routine maintenance and refurbishment programs, including a significant refresh completed in 2024.
What’s particularly notable is that major propulsion or power-related incidents have been relatively rare throughout the ship’s career.
Prior to this latest event, notable technical issues were reported only in:
- 2011
- 2023
- 2026
For a ship with more than two decades of service, that’s actually a fairly limited number of significant propulsion-related incidents.
Waiting for More Answers
For now, passengers aboard Norwegian Sun are still expected to arrive in Helsinki on schedule, and future guests have not been notified of any itinerary changes.
The biggest disappointment remains the loss of Stockholm, a destination many travelers specifically look forward to on Baltic cruises.
Whether repairs are already complete or additional work is still needed remains unclear.
Until Norwegian Cruise Line provides more details, passengers booked on upcoming sailings will likely be watching closely for updates.
The good news is that despite the technical setback, Norwegian Sun was able to continue her voyage, visit most scheduled ports, and keep guests moving toward their final destination rather than ending the cruise early.
