B-Class (under 60 feet), Open

This class was limited to motorboats less than 60 feet in length, and with a total piston area not exceeding that of four cylinders, each of 106 mm bore. It has not previously been published in a book that women competed in this sport, but The Times noted, “it is worthy of special remark as an example of feminine endurance that Mrs. Gorham was also on board”, referring to Sophia Gorham, who competed in the Quicksilver.
