Randy,

The first message indicates that there are some fields of
a type that cannot be translated to shapefiles directly.  With
-skipfailures they should be just skipped.

The second message is caused when an S-57 layer has a mixture
of geometry types.  Shapefiles can only have one geometry
type (ie. line or point) per layer.   The traditional way to
address this is to do two translations for layers with a mixture
of geometries, one for each geometry type.

So you command is reasonable, but to translate S-57 the best
that is possible you will likely need to do the translation
one layer at a time,and establish what geometry types each
has.  Rather tedious!

Best regards,
