The Seaker-100 was a submersible designed for up to three occupants and intended to be marketed for recreational use by its designers, Carl Hardwicke and Greg Hansen.   It was eight feet in length and width, and seven feet in height.   It had four feet of freeboard and a draft of only three feet.   It utilized a square hatch measuring 24 x 21 inches.   The submersible used hemispherical viewing domes on both ends of the cabin and nearly full length viewing panels as side viewports. On April 10, 1990, one or more viewports suffered catastrophic failure at a depth of 38 feet.   Carl Hardwicke lost his life in the incident due to fatal injuries caused as a result of rapid compression of the cabin.   Lack of fluid in his lungs indicates that he did not drown.   Greg Hansen survived the implosion and was able to escape to the surface with severe cuts to his head, and was airlifted to a hospital where he eventually recovered from his injuries. According to sources, Hardwicke and Hansen had practiced emergency escapes from the submersible many times prior to the accident, which may have contributed to Hansen's successful escape.
