The following flags are not considered as colours:
Night Pennant (blue).—Is hoisted at the main truck from sundown to 8 A. M.; also occasionally used as a tell-tale when racing or sailing.
Owner's Absent Flag (blue rectangular).—Is flown from the main starboard spreader when yacht is at anchor only. It denotes owner is not on board, but should never be flown when under way.
Owner's Meal Flag (white rectangular).—Is flown from the main starboard spreader, and denotes the owner is at meals—boarding a yacht when this flag is flying is considered bad form.
Crew Meal Flag (red triangular).—Is flown from the foreport spreader on schooners and main-port spreader on single-masted yachts. This denotes that the crew is at meals.
The Ensign.—Displayed on a vessel indicates distress and want of assistance.
Flag "B," of the International Code of Signals, is used for a protest flag, and is conspicuously displayed in the rigging of a yacht protesting during a race.
A yacht, on withdrawing from any race, should at once lower its racing colours, and allow yachts still competing the right of way.
This code was studied by the boys until both of them thoroughly understood its full meaning, and George became so enthusiastic over it that he exclaimed: "Fred, I am going to be an admiral of the navy!"
