Harmsworth Cup

The Harmsworth Trophy is the popular name of the historically important British International Trophy for Motorboats.

The Harmsworth was the first annual international award for motorboat racing. Officially, it is a contest not between boats or individuals but between nations. The boats were originally to be designed and built entirely by residents of the country represented, using materials and units built wholly within that country. The rules were somewhat relaxed in 1949 and may have been relaxed further since.
