What is the test for "unseaworthiness" in a medical malpractice case?

Perhaps the best that can be done is, like Judge Hand in Grillea v. United States, 232 F.2d 919 (2d Cir. 1956), to take as the starting point a condition of reasonable fitness for intended use, to consider this condition as impaired by the conduct or process which is the subject of litigation, and to call the resulting condition "unseaworthiness." The conduct or process by which the fitness is changed to unfitness is not then to be classified as itself constituting unseaworthiness.
