  • High-resolution modeling of tidal currents, accounting for coastal topography and seabed morphology
  • Visual representation of current fields at every hour of the tidal cycle, in both spring and neap conditions
  • Optimized for professional use in commercial shipping, port operations, and offshore logistics

Engineered for Maritime Operations

  • Digital PDF format for instant access and seamless integration with navigation software
  • Licensed for use on up to 5 workstations, ensuring compliance for fleet or office deployment
  • Free updates for one year, guaranteeing access to the latest tidal data and corrections
  • Secure delivery via download link or WeTransfer, eliminating shipping delays

Trusted by Industry Experts

This atlas is a standard reference for merchant marine professionals, including ship captains, port authorities, and offshore operators. Its accuracy and reliability make it indispensable for navigating the Iroise Sea’s complex tidal patterns, where currents can exceed 3 knots and shift rapidly. Whether for daily navigation, emergency response planning, or long-term route optimization, this tool provides the data needed to make informed decisions in real time.

Beyond Navigation: Environmental and Operational Applications

  • Critical for environmental impact assessments, including marine construction and waste discharge projects
  • Supports port infrastructure planning, such as dredging and harbor expansions
  • Valuable for scientific research, including coastal erosion studies and marine biodiversity monitoring
  • Used by fishing fleets to identify optimal trawling zones based on tidal flow

Seamless Integration into Workflows

Compatible with all major navigation systems, this digital atlas allows for quick cross-referencing with electronic charts and GPS data. Its user-friendly layout ensures rapid interpretation of current patterns, reducing the risk of grounding or collision in high-risk areas. The 2026 edition incorporates the latest hydrographic surveys and model refinements, providing unparalleled accuracy for professional use.
