I went on a small sloop this week with a friend around kaageiland etc. and saw a barch with this mast lying in front of de vries.
Well, you can see the pictures at the link below and a small peek between the doors of the yard.
They had 2 ships under construction and i made a unidentifyable snapshot through the door (very hot that day, so, hence the opened doors).
I might have taken pictures from between the doors, but that might have been a bit crossing the line...
