e. Except for the initial portion of the simulated accelera- 
tion maneuver, the Taylor wake fractions were within three percent 
of their values at the self propulsion point. 
All of the results presented here on a model of the DD-963 Class 
Destroyer follow close to previously reported results of similar experi- 
ments on a model of the FF-1088.
