2.2 Selected Hulls 



Some Todd's hulls have been selected, which may be considered typical for 

 tankers and bulk carriers. The principal parameters characterizing these hulls 

 are reported in Tables 5 and 6, where the following symbols are used (It is to be 

 noted that in Table 6 values of b^/b and A^/A correspond to equally spaced 

 transverse cross sections of body plan, so that section corresponds to aft per- 

 pendicular and section 20 to fore perpendicular.): 



L = waterline length 



Lpp = length between perpendiculars 



B = maximum waterline breadth ^ . . ; 



i = draft (from base line) 



A = maximum surface of immersed transverse cross section (up to 

 waterline) 



B^ = breadth (at waterline level) of actual transverse cross section x 



A = surface of actual immersed transverse cross section x 



Cg = block coefficient 



c^ = waterplane area coefficient 



C = midship section area coefficient 



x^, = center of buoyancy, from aft perpendicular

 Selected Hulls 



The choice of the hull parameters appearing in the tables has been sug- 

 gested by the following partial results, obtained from a preliminary calculation 

 worked out before planning the systematic calculation, which does not appear 

 necessary to expose here in complete detail:
