Stefan Fritz, Dipl.-Ing., MCMS, Senior Associate

Stefan graduated from Stuttgart University with a Degree in Engineering (Dipl.- Ing.) and followed this with research studies at Brunel University UK in Manufacturing and Engineering systems.

On purchasing a "Live-aboard" sailing barge, Stefan began to specialize in marine engineering generally and in particular the design, construction, repair and rebuild of steel vintage and modern classic vessels under sail and power.

Stefan became qualified as a Marine Surveyor and joined BMS to concentrate on vintage steel vessel surveys, living in his own vintage Dutch sailing barge on the River Thames.

In the course of this activity he has become qualified as a sailing vessel charter skipper of coastal barges and an expert on traditional vintage barge sailing rigs. He is now part owner of a square rigged Brigantine charter vessel. sailing mostly during the summer in Scottish waters.

When not skippering either his own home barge or the Brigantine, Stefan is in much demand as a delivery skipper for barges bound between U/K and Europe.
