Imray Nautical Chart (Folio): Precision Expertise for Confident Leisure Sailing

When meticulously planning a voyage, whether for coastal cruising, recreational fishing or a demanding offshore passage, the chart table is the operational centre where safety and efficiency are planned with absolute precision. Imray nautical charts in folio format hold a privileged position in this environment and are recognised worldwide for their outstanding accuracy and reliability. Primarily designed for leisure sailing, they are an essential tool for planning a cruise, navigating safely and exploring coastlines with confidence.

Nautic Way Maritime Bookshop, an authorised Imray agent, offers the complete catalogue of charts and publications from this historic British publisher. With a carefully selected range of 16 folio products covering strategic sailing areas from the North Sea to the Balearic Islands, Nautic Way helps sailors achieve confident and well-prepared navigation. Choosing an Imray folio from Nautic Way means relying on a high-quality document designed by experts with real-world sailing conditions in mind.

What are Imray nautical charts (folio) used for?

The value of an Imray folio lies in its ability to synthesise complex hydrographic data in a practical format, providing an overall view that digital screens can sometimes struggle to reproduce. Unlike individual charts, the folio combines several charts covering the same sailing area, creating a coherent, ready-to-use set.

Practical uses and real-world situations

• Strategic cruise planning: The folio allows sailors to plot routes over long distances while still having detailed charts available for landfalls and approaches. Moving from one area to another is seamless thanks to the continuous cartographic coverage provided by the collection.

• Discovering anchorages and shelters: These charts help identify excellent anchorages and ports that may be overlooked by overly general digital systems, which can be essential for a successful stopover or a safe refuge.

• Navigation in technically demanding areas: Whether dealing with the currents around the Channel Islands (Folio 2500) or exploring the Clyde sea lochs and fjords (Folio 2900), the folio provides the level of detail required for every stage of the voyage.

Added value compared with digital-only navigation

Even in the age of chartplotters and mobile applications, the paper folio retains a major strategic role. Independent of any power source, it provides the ultimate backup system in the event of an electrical failure, GPS malfunction or software issue. In addition, plotting a route manually on paper is often more intuitive and helps sailors better internalise courses and distances, strengthening situational awareness.

What type of sailor are these charts recommended for?

Nautic Way provides solutions for all types of sailors, ensuring that every crew has the right tools for its navigational and safety requirements.

• Leisure sailors and cruising skippers: This is the ideal format for those who want to cover an entire sailing area, such as a complete coastline, without having to manage multiple separate documents.

• Recreational fishermen: They benefit from detailed bathymetric information for identifying seabed features, isolated rocks and wrecks.

• Experienced sailors and professionals: Professional skippers appreciate the reliability and clarity of Imray folios for safe yacht deliveries and offshore passages.

• Beginners and trainees: The folio is an excellent educational tool for learning to read depths, understand coastal morphology and master the rules of navigation.

Reading and understanding the Imray folio

The success of Imray folios is based on a carefully designed graphic layout that allows immediate interpretation of critical information, helping sailors anticipate hazards well before reaching them.

Scales and key navigational information

Each folio combines chart types suited to every stage of navigation:

• Coastal charts: Accurate and detailed for navigation close to the coastline and approaches.

• Offshore charts: Providing a broader view for offshore sailing and longer distances.

• Harbour plans and detailed charts: Essential for complex areas, harbour entrances and sensitive anchorages.

• Integrated nautical data: The charts show vital information such as waypoints, GPS coordinates, landmarks, channels, regulated areas and currents.

Ease of reading and standardisation

The charts feature standardised symbols and contrasting colours that facilitate quick interpretation, even in demanding situations. The layout and folding are specifically designed for convenient use in a vessel's cockpit.

Reliability, updates and safety

The reliability of hydrographic information is the foundation of safe navigation. Imray folios are the result of more than a century of rigorous cartographic tradition.

A rigorous update system

Imray's expertise is based on consultation of official hydrographic offices, complemented by field information collected by experienced sailors. Folios are regularly updated to reflect changes in aids to navigation and seabed conditions. Nautic Way stresses the importance of using a recent edition: this is essential to ensure the accuracy of safety-critical information and minimise navigational risks.

Marine-grade material quality

The folios are printed on durable marine-grade paper designed to withstand moisture and frequent handling onboard. High-definition printing and carefully calibrated colours ensure excellent readability, including under a red light during night passages.

FAQ

Which Imray folio should I choose for sailing in Northern Brittany?
Folio 2510 (Northern France, Brittany – Saint-Malo to Brest) is the ideal solution for covering this technically demanding area with continuous cartographic coverage.

Is this chart sufficient on its own for safe navigation?
Although comprehensive, it should be used together with complementary documents such as Imray pilot guides, almanacs (Bloc Marine, Reeds) and books of lights to ensure comprehensive risk management.

How often should I replace my Imray folio?
Aids to navigation and depths can change regularly. It is essential to use the latest edition before each major cruise to ensure the accuracy of safety-critical information.

Can Imray folios be used with a GPS?
Absolutely. Imray charts include waypoints and GPS coordinates specifically to facilitate correlation between your electronic position and the paper chart.

What is the difference between an Imray folio and a SHOM chart?
SHOM is France's official state hydrographic office. Imray reworks official hydrographic data in a format specifically designed for leisure sailing, with folios combining multiple scales, simplified symbols and contrasting colours for more intuitive use while cruising.
