Abstract
The technical memorandum presents two improved boundary element methods for predicting hdyrodynamic coefficients of two dimensional sections. The first method is a source distribution method, while the second is a direct method for determining velocity potential. A major objective of these improve methods is to eliminate errors due to irregular frequencies, which currently exist in the close-fit method used by the strip theory program SHIPMO. Both new methods successfully eliminate problems caused by horizontal and vertical line segments with the close-fit method.
