The CONCORDIA 40 is also referred to as the CONCORDIA YAWL.
The first 4 CONCORDIA 40's were built in the US. The rest were imported from Germany. A slightly larger version (see CONCORDIA 41) was imported to the US after WWII. (26 boats)

CONCORDIA 40's were built with an oak keel, steam bent oak frames, African mahogany planking, mahogany deck trim, a canvas covered main deck and coach roof.
Ballast was usually iron but sometimes lead.
A testament to the construction standard is that nearly all of these boats survived the twentieth century intact and in sailing condition.
