Stokes was a keen yachtsman and was twice elected vice commodore of the New York Yacht Club.
 The yachts he owned were Nereid, Clytie, Sea Fox and Mermaid.
He was also involved with efforts to standardise the rules used in international yacht racing.

His interests extended to naval warfare.
 He designed a warship, referred to as a globular naval battery that was a floating fortress, typically used for harbour defence.
 The idea came from the story of the British naval use of an island in the Caribbean called Diamond Rock.
 He published and read a paper on his design called, the Ulitima, in November 1905 before the Society of Naval Architects and Marine Engineers.
