The overprint issues used throughout the German colonies were replaced in 1900/1901 with a standardized design, featuring Kaiser Wilhelm II’s yacht, the Hohenzollern II.

The 1901 Yacht Issues can be distinguished from the 1916 / 1919 Yacht Issues by the addition of a lozenge-shaped watermark to the 1916 issues.

The larger format Mark issues of the German Colonies have slight differences in color, perforation, or frame/center types. For a detailed description of the frame/center types, see the guide to Colonial Frame & Center Types.
