€20,000 to maintain a replica ship?

[Epictetus]

A RAT member posted a link to an interesting article on Facebook: Ancient Greek Boat Model Argo at Sea Again.

I was surprised by this:

The boat’s maintenance cost reached €20,000. The works that were done concerned prolonged maintenance of the boat, such as sandblasting and painting, replacement of the sails and maintenance of its 65 paddles.

The maintenance works started with a delay, as the first competition that was made for the assignment of maintenance works brought no result. The boat was ashore for a long time, as it was launched last December.

Am I reading correctly that the Argo was just launched seven months ago but maintenance costs have already reached €20,000? Judging by the picture, it looks to be a huge, fabulous ship, but I'm stunned at how much it costs to maintain it.
