*Net buoyancies of the 6/10-12/59 tests were computed on the basis of 97.4 pounds total buoyancy. 
tNet buoyancies of the 7/27-29/59 tests computed on the basis of 102.0 pounds total buoyancy. 
+Weights, metacentric heights, and gyradii do not include the effects of inadvertent flooding water. 
§See Table 4. 
Since it was known that the shape and size of external appendages would strongly influ- 
ence the damping of any oscillations, two different sets of bilge keels and stern fins were 
made to be fitted to the model. These are described in Table 4 and identified in Table 3.
