 The main reason was that with the creation of the Greek state, Hydra's fleet lost the privileges that the Treaty of Küçük Kaynarca and the use of the Russian flag had given it.Another reason was that the traditional families who owned the majority of the fleet failed to foresee the benefits of participating in the steam ship revolution, which significantly cut shipping operational costs through reduced crew and independence of the winds, putting them at a disadvantage vis-á-vis the new shipping companies of Piraeus, Patras, and Syros.A third reason was that the new conditions made illegal activities such as piracy impossible.
