Two distinct aspects of computer aided ship design are addressed in this thesis. First, a geometrical hull form modification technique employing the longitudinal repositioning of sections is developed. The second aspect deals with the mathematical representation of lines and line fairing. Before this is however, justification is presented for utilizing thrid degree polynomials as an approximation to the spline curves of the nanal architect. The results obtained indicate that a fairing procedure based on a least squares curve fitting criteria and a lines representation procedure based on parametric cubic equations could be adapted to generate faired hull forms from the roughest preliminary hull design. Additionally, the hull form modification technqiue could be programmed so as to produce the designs with desired values of C sub p, LCB,. C sub w and LCF from a basis design of similar texpe.
