To minimize the negative impact each boarding has on the ship, boarding for visitors is prohibited. There are exceptions, for example authorized staff from the Vasa Museum, who go on board to do maintenance, so that we can preserve the Vasa for future generations.
The Vasa Museum started the project "Stötta Vasa" (Support Vasa) in 2024, which refers to a new support structure to hold up the ship. New research has shown that the support cradle Vasa has today, does not provide enough support. The Ship needs both external cradle and an internal skeleton.
