^fWAVEL = Number of wavelengths at which computations are 



to be performed. 

 ISYM = 1 for symmetric section. 



= Anything else for non-symmetric section.

Do not solve equations of motion, 

 2 Do not solve potential problem (read in 

 coefficients from data) , 

 = Anything else solve potential problem and equa- 

 tions of motion. 

 Number of body segments which represent spaces be- 

 tween multiple hull configurations (1 to 5). 

 Designates the segment number for segments repre- 

 senting spaces between multiple hulls. 

 Parameter card, Format (5F10.3,3A10) . 

 AREA = Crossectional area of immersed body. 

 B = Characteristic beam as specified by BTITLE. 

 D = Distance below free surface to origin of users 



coordinate system (all motions are referred to that 

 point) . 

 ROE = Fluid density. 

 GEE = Acceleration of gravity. 

 BTITLE = Specifies B. 



Beam/wavelength specification. Format (10F8.5). 

 BOL = Beam/wavelength ratios for computation (up to 10 



different ratios may be used) . 

 Offset cards. Format (2F10.3). 



There must be N+1 cards giving the offset points. In the 

 version of the program used here, N must be less than or 

 equal to 23 because of dimension statements. 

 R(1,I) = X-coordinate of offset point. 

 R(2,I) = Y-coordinate of offset point. 

 Hydrostatic spring constants. Format (9F8.3). 

 This is read in subroutine DYNAMC.
