heal.abstract	A three-parameter extended-Lewis form family is considered and investigated. The parameters used are the half beam to draft ratio lambda , the area coefficient sigma , and the KB to draft ratio k, where KB is the vertical distance of the centroid of the section from the keel. The region of values lambda , sigma and kappa corresponding to conventional, free of deficiencies, ship-like forms is investigated and determined. Various applications of the extended-Lewis forms to ship hydrodynamics are discussed. It is demonstrated that the hydrodynamic characteristics (added mass and damping coefficients) of ship-like forms depend considerably on the kappa parameter. Refs.	en
