.. International Sonder Class

International Sonder Class

The class originated in Germany, the restrictions being drawn up there, and a great number of boats have been built, for, to begin with, there was a cost limit of only $1224, which now has been raised to $1440 in Germany and to $2400 in the United States. This allowed even the men of small means to own and sail a racing craft, and in order to hold and increase the interest the Emperor of Germany offered valuable prizes to be sailed for each year during Kiel Week, and as many as twenty-five boats sometimes competed for them for the Samoa-Pokal in Kiel. In the German-American races three American and three German yachts took part.

Niagara und Meteor

The first boat built in America was the "Uncle Sam," in 1902. She was shipped to Kiel where she succeeded in winning the Emperor's Gold Cup, after which she was purchased by his Majesty. Her name was changed into Niagara. Later she had been given to the Navy for the purpose of educating officers for the handling this small racing type.
