Description

International Code of Signals Pennant — Numeral One (1)

The International Code of Signals Numeral One (1) Pennant is part of the standardized maritime signaling system used worldwide for numeric communication at sea. As a result, mariners rely on numeral pennants aboard commercial vessels, naval ships, and recreational boats to convey precise numerical information.

These pennants allow vessels to display numbers individually or in sequence. Moreover, they remain especially effective when radio or electronic communication becomes limited. Consequently, the One pennant supports clear, internationally recognized signaling across marine environments.

International Code of Signals — Numeral Meaning

Numeral: 1
Spoken As: One

When displayed alone or combined with other numeral pennants, the One (1) pennant contributes to numeric messages involving courses, distances, bearings, time references, and vessel identification.

Made by Advertising Flag Company — Marine-Grade Construction

Advertising Flag Company / FlagPro proudly manufactures all International Code of Signals flags and pennants, ensuring consistent quality throughout the entire Code of Signals series.

Each pennant is produced using Glaser Mills marine-grade nylon, selected for its strength, excellent color retention, and resistance to sun, wind, and saltwater exposure. In addition, the lightweight weave allows the pennant to stream cleanly and remain highly visible while underway.

Available Sizes — International Code of Signals Numeral Pennants

The Numeral One (1) pennant is available in multiple standardized pennant sizes, which differ from the square alphabet flags. As a result, mariners can select the appropriate length for vessel size and hoist visibility.

• Size #0: 8″ × 24″ (20 × 60 cm)

• Size #2: 16″ × 36″ (40 × 91 cm)

• Size #3: 16″ × 36″ (40 × 91 cm)

• Size #7: 24″ × 54″ (61 × 137 cm)

• Size #10: 32″ × 72″ (81 × 182 cm)

• Size #14: 32″ × 108″ (81 × 274 cm)

Because these pennants follow international proportions, they integrate seamlessly when flown as part of a complete numeric hoist.

Canvas Heading with Solid Brass Grommets

Each International Code of Signals numeral pennant includes a canvas heading with solid brass grommets, which serves as the only and standard finishing option.

This construction allows secure attachment to signal halyards. Additionally, it delivers durability for repeated hoisting and long-term outdoor marine use.
