During the visit, Their Majesties unveiled a commemorative plaque on the vehicle deck of Hull 102, the first of three 129-metre vessels currently under construction for Denmark.

When delivered, the vessels will be Europe's largest battery-electric ferries and will operate across the busy Kattegat route between Jutland and Zealand, carrying thousands of passengers each day.

The project forms part of the largest electrification initiative ever undertaken in the ferry sector and represents a major step forward in the transition to cleaner maritime transport.

Incat Managing Director Craig Clifford said it was a great honour to welcome the Danish Royal Family to the shipyard.

"It is a privilege for everyone at Incat to host King Frederik and Queen Mary and to showcase the work our team is doing here in Tasmania," Mr Clifford said.

"Denmark is one of the world's great maritime nations and we are proud to be partnering with Molslinjen on this remarkable project.

"These vessels demonstrate what can be achieved when world-leading operators and shipbuilders work together to deliver innovative and more sustainable transport solutions.

"Today's visit is a proud moment for the hundreds of skilled workers helping build these vessels here in Tasmania."

Molslinjen CEO Carsten Jensen said the company was honoured that Their Majesties had visited Incat to inspect the first of the new battery-electric ferries being built for Denmark.

"Unfortunately, we have had to watch from a distance, but it is of course an honour and a great pleasure to see our upcoming vessels in the company of the royal couple – and it will be an even greater pleasure in a few years when the world's largest maritime electrification project culminates with the first ferry sailing silently into Aarhus Bay, marking a major green breakthrough for high-speed ferry travel."

Following the plaque unveiling on Hull 102, Their Majesties and Prime Minister Albanese toured Incat's recently completed Hull 096, a 130-metre fully electric vessel for long-term customer Buquebus, including a visit to the ship's battery rooms.

The visit highlighted the strong and enduring ties between Tasmania and Denmark, as well as the growing global demand for large-scale electric ferries.
