Developments in Theory of Bulbous Ships 



The axisymmetric fish form body has been split into two and has been fitted 

 in different positions on the ship as shown in Fig. 3. 



The comparative curves of resistances of the original naked model and that 

 of a composite configuration having a bulb fitted at stem on the designed water- 

 line in combination with a circular segmental suppressor of hydrofoil section 

 (curved on top, Fig. 4), This model with (WL bulb plus suppressor) has shown 

 itself of having less resistance after a model speed of v = 1.60 m/'sec approxi- 

 mately equivalent to F^ = 0.217, F = 0.292 and a V L = 1.00.
