Controversy about the Maintenance Costs of Beatrix' Sailing Yacht

[Marengo]

As posted by Marianne on the Benelux Royals MB

Several Dutch news-papers are publishing an article about the (rather extreme) high maintenance costs of the Queen's private sailing boat 'De Groene Draeck' (which she received upon her 18th b'day).
Seems the Ministery of Defence has been paying Euro 112,000 per year for the maintenance of this private boat (wouldn't call it a yacht anyhow!) and since the annual budgets are made public nowadays, these specific (extra) costs for this Department have come out in the open.
The boat is mostly used for private trips and only - occasionally - used by the Queen or the Prince of Orange in their official capacity, like when they are viewing 'Sailing Amsterdam' for example.
Some may remember seeing Queen Beatrix and the Eikenhorstertjes on this boat for a picture-shoot in the harbour of pittoresque Muiden (RVD pic below).
