JP,

I just tried a similar conversion and it worked for me.  The resulting
S-57 file did have wrecks.  I did observe that the new DSID feature class
support is not supported by the writer.

Are you confident that the double quotes did not get included in your
OGR_S57_OPTIONS senvironment variable?  Does an ogrinfo on your original
file show layers called IsolatedNode, ConnectedNode, Edge and Face (as
well as the regular feature classes)?

Best regards,
