Michał Szczepaniak

msFor Michael diving is a tool for the discovery and exploration of the places to which few have access, supposedly an adventure reserved only for the few. It turns out, however, that many people share the passion for diving. There are many people who believe that today you can still discover something undiscovered, that the seas and oceans are full of shipwrecks, which from the moment of their sinking remain untouched by human hands.  In many cases these wrecks often hold hidden secrets, treasures, and stories which ignite the imagination and are a huge incentive for exploration. The green waters of the Baltic Sea are no exception and for centuries turbulent history has left many secrets on the bottom. Thanks to his passion Michael can explore wrecks and admire their beauty and their stories while searching for his “Grail”.

During the day he is a marketing specialist and after hours a seeker of wrecks and their secrets. I am interested in climbing and sailing and am fascinated by history and in particular  the history WWI and WWII at sea.
