Simple formulas for determining impact strength of high-speed
craft collisions with floating objects are given in this note.
Thereby the minimum mass of a floating object that just ruptures
the shell plating is predicted. The minimum thickness requirements
of DNV rules for aluminiumcrafts and GRP single skin crafts can be
converted to critical impact energy and minimum object mass. Some
comparisons show an acceptable agreement between present method
and DNV test results.
