SCI has conducted informal mariner training since 1899 and mariner education since World War I. When retired sea captain Robert Huntington directed SCI’s Navigation and Marine Engineering School in February 1916, instruction included nautical astronomy, navigation, marine engineering, mathematics, seamanship, and signaling. The school targeted seamen hoping for career advancement as well as those who dreamed of going to sea, encouraging many young men to enlist in the Navy: “Any person who wishes to follow the sea should join the United States Navy…. The fact is that if any young man has the right kind of American push in him the Navy is the best place to bring out and develop all the good points that are in him,” one school circular proclaimed. For those already enlisted in the Navy, the school offered preparation for the Naval Academy’s highly competitive entrance exam. “Out of the large number of applicants only the top one hundred (100) obtain appointments, so that every candidate should prepare himself to pass the best examination possible,” read the brochure.
