"Jeroen Noot" schreef in bericht Nice picture,

it's the "Urania" used by the Royal Dutch Naval Academy (Koninklijk
Instituuut van de Marine) to train officers. More info (Dutch only) on:
http://www.marineschepen.nl/marschepen/urania.html

She has replaced a 1928 built training vessel of similar design, which
almost fell apart from extensive and hard use...

She's back in Den Helder (her homeport) after an extensive cruise to the
USA.

Thanks for the info Jeroen.
