Navigate Southern Brittany’s Tidal Waters with Unmatched Precision
This digital tidal current atlas is the definitive resource for professionals operating along the Southern Brittany coast, from Audierne to Le Croisic. Engineered for commercial shipping, fishing fleets, and environmental agencies, it provides hourly surface current data across four high-traffic sectors: Penmarc’h, Groix-Lorient, Quiberon Bay, and the Gulf of Morbihan. With 12 detailed maps per sector, covering both spring and neap tides, this tool ensures safer, faster, and more efficient maritime operations in one of France’s most dynamic coastal regions.
Built on Advanced Hydrodynamic Modeling
Leveraging cutting-edge hydrodynamic simulations, this atlas integrates tidal patterns, bathymetric data, and coastal geography to deliver unparalleled accuracy. The Mercator projection guarantees geospatial precision, making it ideal for route optimization, port planning, and environmental impact assessments. Whether navigating narrow channels or open waters, users gain real-time insights into current behavior, reducing risks and operational costs.
Optimized for Professional Workflows
Designed for merchant mariners, port authorities, and offshore industries, this digital atlas is licensed for use on up to 5 workstations, ensuring accessibility for vessel crews and shore-based teams. Delivered as a PDF via secure download link, it offers instant access with free updates for one year, maintaining data relevance in evolving maritime conditions. Its unlimited validity ensures long-term utility, making it a cost-effective investment for any professional operation.
This digital tidal current atlas covers the Southern Brittany coast from Audierne to Le Croisic, featuring 48 high-resolution maps (12 per sector) detailing surface currents at hourly intervals. Based on semi-diurnal tidal cycles, it includes data for both spring and neap tides, with a Mercator projection for geospatial accuracy. Delivered in PDF format, it supports use on 5 workstations and includes free updates for one year.
