Sometime ago, we published Lilla Weneda, one of 10 sister ships built in 1961-64 with the code SZ-600. Then 8 +2 new ships built with code SZ-390 . Ewa is one of them, with slight differences. So it is worth to publish her plans. Ewa was still in service in 2012 and hope she will serve for many long years.
The plans are very detailed and clear. Would be great to build her scale model.
