~ Dem Freunde Schutz, dem Feinde Trutz ~
 
This appears to be a generic destroyer of the German Navy and is unnamed, but might also be the SMY Hohenzollern II, the private yacht of Kaiser Wm II. The stein is marked "1547 14", ca. early 1900's.
 
Dem Freunde Schutz,
dem Feinde Trutz.
To the friend protection,
to the enemy defiance.
