STABILITY OF LIFEBOATS. 



135 



and dynamical stability. The following table gives the characteristics of form, 

 center of gravity, etc., of all the types used and Plate 78 gives the displacement 

 curves and plots of all the hull functions : 



*With load partly on bottom. 



Plate 80 gives the curves of statical stability (in terms of righting moment) 

 for the boats in the fully loaded condition (allowable load) except in the case of 

 the collapsible, and the following table is derived therefrom: 



*Curve drops from 5,900 to at 30°
