In this presentation, Captain Joe Mazraani and Jennifer Sellitti of dive boat Tenacious will focus on the discovery of ships hunted by U-53 off the coast of Nantucket on October 7, 1916 with emphasis on the captivating history of the Stephano, a steamship from the Red Cross Line located and identified by Captain Eric Takakjian in the 1990s. The presentation is comprised entirely of photographs and video sourced from underwater dive videos, museum archives, newspapers, interviews with survivors, and U-boat commander logs.
