Obviously, these percentages are generali- 

 ties and cannot be applied to a specific vehi- 

 cle. The most perplexing values to attain are 

 those for instruments which vary widely 



from one manufacturer to the next. Chapter

 scientific instrumentation and essentially re- 

 flects curi'ent state-of-the-art. Table 6.1 pre- 

 sents calculations prepared for a vehicle pro- 

 posed by International Hydrodynamics and 

 serves as an example of the data needed for 

 weight, volume and buoyancy calculations.
