This collection will discuss the 18th-century educational, scientific, and technological context for Bushnell's "sub-marine vessel" - which included innovations such as the screw propeller - and the 21st-century educational rewards of the challenging replication project.
The following images and associated text are taken from a PowerPoint presentation on the Turtle effort and the book written by Roy Manstan, FOSA member and former engineer at the NUWC, and Fred Frese‚ project director, Old Saybrook High School.
