Built for Real Signaling Use
Made in the USA to commercial-grade standards, this flag holds up to regular hoisting, weather, and sun exposure, making it a reliable choice for boat owners, marinas, yacht clubs, and any vessel that needs to fly accurate ICOS signals. Delta also has a well-known standalone meaning in the code: "Keep clear of me; I am maneuvering with difficulty."
Who Uses These

Flag Sizing Guide
Nautical alphabet flags are sized by number, not by the inch dimensions used on garden or house flags.
