Maritime Hazard Symbol - Boat in Restricted or Dangerous Waters #1315013 (License: Personal Use)

The image is a high-contrast black-and-white pictogram depicting a stylized boat moving diagonally across wavy lines representing water, intersected by a central circular symbol-commonly used to denote danger, prohibition, or a submerged obstacle. The design follows ISO or IMO standards for maritime signage, ensuring immediate recognition by mariners regardless of language. Its clean, geometric form supports scalability for use on buoys, charts, and digital navigation systems.

This symbol appears on nautical charts, coastal warning signs, buoyage systems, and marine safety documentation to alert vessels to hazards like underwater obstructions, exclusion zones, or restricted areas. It matches user intent for understanding maritime safety symbols, regulatory compliance, or emergency response planning.
