Abstract
Systematic series of hulls based on a parent hull have long been used by naval architects and hydrodynamicists to determine the effects of hull form on flow and resistance. The memorandum describes an interactive computer program, MODHLL, which creates modified hulls from an existing parent hull. Although the parent hull requires a large data file for its definition, each modified hull is defined by only a few extra words of data since only the way it differs from the parent needs be defined. Thus a whole series of hull forms may be defined using only a little extra storage space than the parent.
