The are still problems with -slosh. This time it is for tanks which
are 100 percent full - the resulting GM is too high. Also, the
cg for tanks flooded without -slosh is not correct if the density of
their contents is not sea water.

A pipe with an articulated stinger gives bad pipe stresses in
the frequency domain due to and inadequate handling of the
stiffness of the pipe.
DATE: October 03, 1996 Discovered By: Peter Lai
This is simply a continuation of a previous fix having to do
with the manner in which ballast is treated. Here, a small problem
with the corrected cg of tubtanks is fixed. Also, the reporting
of radii of gyration (in both &status and at the top of the
motions reports) has been changed from "dry" to "wet".
