Hotel Code H Marine Signal 3×3 Ft Flag – Printed 200D Nylon – Canvas Header – Brass Grommets – Colorfast & Stitched Edges – Nautical Boat Flag – Naval Code Signal Flag.

Under International Code of Signals standards, different flag shapes represent different categories of messages to ensure instant recognition at sea. **Alphabet letters (like Code H) are strictly square (1:1 aspect ratio)**, whereas numeral pendants are elongated triangles and substituters are swallow-tailed pennants. Our 3x3 ft square flag maintains this exact official ratio so it can be read clearly by binoculars from distant vessels without visual distortion.

This flag features two standard #2 solid brass grommets anchored into a reinforced white duck canvas header. It is designed to attach easily to standard **vessel rigging halyards, signal yardarms, outriggers, or balcony flagpoles** using standard brass snap hooks, carabiners, ash toggles, or rigging shackles.

200 denier nylon is the premier commercial fabric for nautical ensigns and signal flags because it offers exceptional tensile strength while remaining lightweight. Thin printed polyester novelty flags absorb water and deteriorate rapidly when exposed to saltwater spray, sea air, and high-speed wind loads on rigging halyards. Our 200D marine nylon sheds water instantly, resists saltwater and UV sun degradation, and flies gracefully even in light maritime breezes.

Yes, our flag features two solid #2 brass grommets that are inherently anti-rust and corrosion-resistant, making them ideal for coastal, harbor, and offshore marine environments. They are securely set into a heavyweight white duck canvas header to ensure they will not discolor your halyard rigging or pull out under normal vessel wind loads.

To maximize the lifespan of your marine signal flag, rinse it occasionally in fresh lukewarm water with mild detergent after saltwater boating trips to wash away dried salt crystal buildup before it abrades the nylon fibers. Hang it flat to air dry completely before returning to cabin locker or flag bag storage. Never store a folded wet flag in a boat locker, as trapped moisture can cause mildew over time.
