This article is the historic first Panama Canal transit of the Star Princess. It is about the April 20, 2026, passage of the newest Sphere Class vessel through the engineering marvel of the Americas as a positioning move to Seattle for her inaugural Alaska season.

The Star Princess is a massive engineering achievement. It weighs 177,800 tons and carries approximately 4,300 guests. On April 20, 2026, this vessel completed its inaugural transit through the Panama Canal. This event was not just a general canal milestone. It was a repositioning move that brought the ship from the Atlantic side of her early deployment toward the Pacific Northwest for her first Alaska season. As a travel advisor who keeps a close eye on fleet movements, I see this transit as an operational milestone with a clear next step: getting Star Princess into place for summer sailings to Alaska.
The Significance of the Sphere Class

The Star Princess is the sister ship to the Sun Princess. These ships represent a new era for Princess Cruises. They are the largest ships ever built for the line. The “Sphere” name comes from the ship’s most distinctive architectural feature: a massive glass sphere integrated into the side of the hull. This design allows for unprecedented views of the ocean and, in this specific case, the narrow walls of the Panama Canal.
During the transit, guests on board were treated to enrichment presentations. Destination experts provided live commentary as the ship moved through the Gatun, Pedro Miguel, and Miraflores locks. For a ship of this size, the clearance is minimal. The Star Princess utilized the Neopanamax locks, which were specifically designed to accommodate the larger “New Panamax” class of ships.
A Look at the 2026-2027 Panama Canal Season
The transit of the Star Princess is the kickoff for a very ambitious 2026-2027 season. Princess Cruises is doubling down on its presence in the region. The program is extensive:
- 6 Ships: A total of six Princess vessels will be deployed to the region.
- 31 Departures: There are over thirty scheduled departures across various itineraries.
- Historic vs. New Locks: The season will feature 13 transits through the historic locks and 26 transits through the newer, larger locks.
Princess Cruises has a long-standing relationship with the Panama Canal. They pioneered regularly scheduled cruising through the waterway back in 1967. Before that, transiting the canal was largely the domain of cargo ships and the occasional private yacht. By bringing the “Love Boat” brand to the canal, they transformed an industrial shortcut into a bucket-list travel destination.
Life Onboard the Star Princess

While the canal transit was the main event last week, the ship itself is the destination for many travelers. The Star Princess is powered by Liquefied Natural Gas (LNG), which is a much cleaner-burning fuel than traditional marine diesel. This is part of a broader industry shift toward sustainability.
Inside, the ship feels more like a floating boutique hotel than a traditional mega-ship.
For those who enjoy the “suite life,” the Star Princess offers the Signature Collection. This includes access to a private restaurant, lounge, and sun deck. When you are transiting the Panama Canal, having that extra bit of space on a private deck is a game-changer for photography.
From the Canal to the Great Land
The Star Princess did not stay in the Caribbean or Central America for long. After completing its April 20 transit, the ship continued its 20-day journey from Fort Lauderdale toward Seattle. This was a positioning voyage. Its purpose was to bring the ship into place for her inaugural Alaska season.

From May through September 2026, the Star Princess will be sailing 7-day Alaska cruises out of Seattle. That is the bigger story here. Princess is using the Panama Canal transit as the bridge between the ship’s earlier deployment and her first summer in Alaska. Alaska remains one of the line’s core regions, and assigning the newest Sphere Class ship to Seattle is a direct statement about that market. Guests will move from canal lock views to Inside Passage scenery in a matter of weeks.
Why This Transit Matters for You
If you are watching where the Star Princess is heading next, this canal transit matters because it directly sets up the ship’s Alaska debut. Historically, Panama Canal crossings can stand alone as destination sailings. In this case, the transit also served a logistical role by positioning Princess Cruises’ newest ship for summer operations in Seattle.

With the Star Princess, the story is not only about a historic canal crossing. It is also about how Princess moved a brand-new 177,800-ton ship into place for Alaska, where guests will soon trade lock walls for glacier views and coastal scenery.
The 2026-2027 season offers several ways to see the Canal:
- Full Transit: Moving from the Atlantic to the Pacific (or vice versa), usually between Fort Lauderdale and Los Angeles/San Francisco/Seattle.
- Partial Transit: Entering the Canal, staying in Gatun Lake for the day, and then exiting back the way you came. This is common for 10-day round-trip sailings from Florida.
Technical Excellence and Captain’s Pride
Captain Gennaro Arma, who is well-known in the Princess fleet, led the transit. In his communications regarding the event, he emphasized the precision required. The Sphere Class ships are wide. Even in the Neopanamax locks, there isn’t a lot of room for error. The ship uses a combination of its own propulsion and “mules” (the locomotives on tracks alongside the locks) to stay centered.
The engineering of the Star Princess is designed to handle these tight spaces. The ship features advanced bridge technology that gives the pilots and the Captain a 360-degree view of the hull’s position relative to the lock walls. This is crucial when you have 4,300 guests on board waiting for that perfect photo of the lock gates closing behind them.
Planning Your Next Journey
The news of the Star Princess’s successful transit is a green light for anyone waiting to book Alaska in 2026. The ship has completed the positioning move through the Panama Canal and is now set for its inaugural Alaska season out of Seattle.
Princess Cruises continues to lead in this space because they understand how to connect ship deployment with destination demand. Since 1967, they have built a reputation around Panama Canal cruising. Now they are using that same operational reach to place a Sphere Class ship into one of their most important seasonal markets.
If Alaska is on your list, Star Princess is no longer just a ship that passed through the canal. It is a new option for sailing the Inside Passage during its first season in the region.
