Master the Atlantic Tides with Professional-Grade Precision
This comprehensive tidal currents atlas delivers the critical data maritime professionals need to navigate the challenging waters of the Bay of Biscay. Covering the entire Atlantic coastline from Brest to Saint-Jean-de-Luz, this printed reference provides hourly tidal current information for both mean spring tides (coefficient 95) and mean neap tides (coefficient 45), enabling precise operational planning in these dynamic maritime environments.
Engineered for Professional Maritime Operations
Developed specifically for merchant marine applications, this atlas features Mercator projection charts that clearly display current fields at each hour of the tidal cycle. The semi-diurnal tidal patterns characteristic of the region are presented with contour lines indicating equal water heights, providing a complete picture of tidal dynamics. This technical foundation supports efficient route planning, fuel optimization, and schedule adherence for commercial shipping operations.
Durable Construction for Challenging Marine Environments
The printed format measures 26.5 x 19 cm and weighs 1 kg, designed to withstand the demanding conditions of professional maritime use. The paper construction ensures reliable access to information without dependence on electronic systems, making it an essential backup for onboard navigation equipment. The 2002 edition remains valid indefinitely, offering a permanent reference that maintains its value over time.
Versatile Applications Across Maritime Industries
Beyond commercial shipping, this atlas serves multiple maritime sectors including fishing operations, port authorities, renewable energy developers, and environmental researchers. The detailed current data supports everything from efficient fishing ground access to tidal energy site selection and coastal management projects. For regatta organizers and participants, the atlas provides the technical foundation for competitive strategy development based on accurate tidal predictions.
