Netted Day Signal Shapes – Marine Vessel Signalling

Netted Day Signal Shapes are masthead visual signals used on vessels during daylight hours to indicate a vessel’s operational condition or status to other ships. They are commonly displayed when a vessel is anchored, aground, restricted in manoeuvrability, engaged in special operations, or required to show a specific navigation status.

Manufactured in a lightweight black netted construction, the shapes are designed for good daytime visibility while remaining easy to handle, hoist and store onboard.
