koningin juliana and enter and you see the ship is built in 1975 and so on
The vessel was originally built as a fishery school training ship. (Stern trawler for pelagic fishing and trawling) until the mid eighties it was used as a pure fishery schoolship. when the schoolship Prinses Margriet was decomisioned the koningin juliana was also used as a trainingship for the dutch seafaring schools.
I sailed on her twice. once in 99 en once in 2000 think I stil have some pictures will try and find them in my archive.
After years and years of sailing as a training (cadet) ship the foundation whom operated the vessel didn't had the funds to maintain the vessel anymore. so it was sold. As far as I now it has been sold to youthwork
a semi goverment institution who works with youngsters who are hard to handle. By putting a group of young problemmakers on board guided by a crew of social workers the youngsters are trained in controling and improving themselves
by the way look at this link for the site of youthwork. Sory its in dutch only: http://www.den-engh.nl/pages/maritiemkoninginjuliana.html
