Finally a note about the methods used during the development 

 of the simulation. The work was not done in a theoretically rigorous 

 manner but rather the simulation was built upon the background of 

 the personnel involved in its development and their ability to apply 

 existing theories to the problem, A number of the elements in the 

 complete simulation of the vehicle dynamics reflect engineering 

 judgment and experience. The major output of the study was re- 

 quired on a tight schedule and relatively little new theoretical 

 analysis were initiated. Since the DSRV is presently preparing 

 for sea trials the validity of the simulation should soon be checked 

 and correlation between the sea trials data and the results of the 

 simulation should provide valuable insight for futher simulations.
