FLSTAB: RECREATIONAL SMALL BOAT FLOODED STABILITY PROGRAM

A computer program is described which may be used to determine the equilibrium attitude of flotation and stability of a craft afloat in calm water with its interior volume flooded in free communication with the outside. The intact, buoyant portion of the craft comprises the thickness of its hull material plus other specific intact volumes. These are described either by giving a description of a series of transverse sections through each intact volume, or by describing horizontal, transverse, and longitudinal planes which form their boundaries. Several intact volumes of each type may be present and each may be partly permeable. The initial condition is described by giving the weight and center of gravity location of each of a group of items which make up the total weight of the craft and its contents. Output of the program consists of the intact drafts and heel angle, the flooded equilibrium position, and a table of righting arms versus heel angles in the flooded condition. (Author)
