Abstract: The effect of a fairly large keel on the rolling characteristics of a hospital ship, attending the fishing fleet, has been studied by means of the corresponding model performing forced oscillations in still water. The results of the rolling tests arc analysed and the increase of the damping and of the mass moment of inertia due to the keel arc determined. A comparison is made between the rolling of the model without and with the keel in an irregular sea at zero speed of advance.
