Imray Atlantic Ocean Nautical Charts: Precision Expertise for Mastering Offshore and Coastal Navigation

In the meticulous planning of a voyage, whether it is intended 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 rigour. The Atlantic Ocean, with its diverse environments — from the rugged coastlines of Brittany to the coral passages of the Caribbean — requires nautical documentation of exceptional precision. Imray nautical charts hold a privileged position in this environment, being recognised worldwide for their outstanding accuracy and reliability.

Nautic Way Maritime Bookshop, an authorised Imray agent, offers the complete catalogue of this historic publisher to support every sailor in their projects, from short trips to long-distance cruising. Choosing an Imray chart from Nautic Way means relying on a high-quality document, regularly updated and designed to meet the demanding requirements of Atlantic navigation.

What is an Imray Atlantic Ocean nautical chart used for?

The value of an official Imray nautical chart lies in its ability to synthesise complex hydrographic data and turn your navigation chart into a strategic decision-making tool.

Practical uses and real-life situations

The Imray paper chart is the preferred tool for cruise planning. It allows you to:

• Plot a route precisely: measuring courses and estimating distances helps embed the information in your memory, strengthening awareness and vigilance at sea.

• Discover outstanding anchorages: identify bays and harbours that may be overlooked by overly general digital systems, which can be essential for a successful stopover or a safe refuge.

• Master technical areas: whether rounding Ushant and crossing the Raz de Sein (C36 chart) or navigating in the Caribbean (A series), the chart provides the necessary details on seabed depths, rocks and shoals.

• Anticipate hazards: the broad and intuitive view of the area makes it possible to interpret currents, buoyage and regulated areas well before reaching them.

Added value compared with digital navigation alone

Although digital tools have become ubiquitous, the Imray paper chart provides an overall view that even a large screen can struggle to offer. Its major advantage is complete independence from any power source. It works without a battery, GPS signal or dedicated equipment. In the event of an electrical failure, loss of signal or software malfunction, the Imray paper chart remains an essential backup navigation system because it is always readable and immediately ready for use.

Which type of sailor is this chart recommended for?

Nautic Way provides solutions for all types of sailors, ensuring that every crew has the right navigation tool for its needs and cruising area.

• Cruisers and cruising skippers: The folded format is ideal because it is practical and easy to handle on board, particularly in the limited space of a cockpit.

• Recreational fishermen: They favour charts showing seabed details, isolated rocks and wrecks to optimise their trips while respecting regulated areas.

• Experienced sailors and circumnavigators: For transatlantic passages, passage charts such as Chart 100 (North Atlantic) provide the cartographic consistency required for extended routes.

• Learning and education: A paper chart is an excellent way to learn how to read depths and understand coastal variations, fundamental skills for any skipper.

• Day and night navigation: Thanks to high-definition printing with clear colours, the chart remains easy and comfortable to read, even under a red light during night passages.

Reading and understanding an Imray chart

The success of Imray charts is based on a century-old graphic design approach developed for fast and intuitive reading while navigating.

Chart scales and categories

The catalogue allows sailors to select precisely the appropriate level of detail for each stage of navigation:

• Passage Charts: For large-scale strategic planning (e.g. Chart 100 for the North Atlantic or Chart 1 for the Eastern Caribbean).

• Regional charts: Covering entire maritime areas to provide continuity during extended cruises.

• Coastal charts: Ideal for coastal navigation, providing detailed information on bays, buoyage, channels and rocky areas (e.g. C37 from Raz de Sein to Bénodet).

• Harbour plans and detailed charts: Essential for navigating complex entrances or locating precise anchorages (e.g. A131 for Culebra Island).

Visual design and key information

Each chart features an intuitive layout:

• Standardised symbols and contrasting colours for immediate understanding.

• Integrated data: waypoints, GPS coordinates, currents, landmarks and boundaries of regulated areas.

• Folio format: providing wider coverage and optimal reading comfort for sailors who prefer a broader view.

Reliability, updates and safety

The reliability of hydrographic information is the foundation of safety at sea. Imray charts are the result of a rigorous cartographic tradition.

A certified updating system

The expertise of British publisher Imray is based on consultation of official hydrographic services. This data is complemented by information collected directly from experienced sailors, ensuring that the charts remain closely aligned with real-world conditions. Nautic Way stresses the importance of checking the edition and publication date: using a recent chart is essential for having accurate information on buoyage, depths and local regulations.

Material quality and durability

Imray charts are designed to withstand the demanding conditions of the marine environment. They are printed on durable paper, specially treated to withstand moisture and repeated handling on board. As a complement to digital systems, which provide precision and zoom capabilities, paper charts offer the resilience needed in the event of unexpected technological failures.

FAQ

Which nautical chart should I choose for sailing in southern Brittany?
The choice depends on your sailing area. For the area from Raz de Sein to Bénodet, Chart C37 is essential. For the continuation towards Quiberon, choose C38.

Is this chart sufficient on its own for my safety?
Although comprehensive and reliable, a nautical chart should be used together with complementary publications such as Imray sailing guides, almanacs (Reeds, Bloc Marine) and light lists to ensure comprehensive risk management.

How often should I replace my Imray chart?
It is essential to use the most recent edition before every major cruise. Changes to buoyage, depths and local regulations can make older charts potentially unsafe.

Can Imray charts be used with a GPS?
Absolutely. Imray charts are designed to complement electronic navigation systems. They include waypoints and GPS coordinates specifically to make it easier to transfer and check your position.

What is the difference between an Imray chart and a SHOM chart for the Atlantic?
SHOM is the French official hydrographic service responsible for producing the underlying hydrographic data. Imray reworks this information with a design specifically adapted to leisure sailing: simplified symbols, contrasting colours for rapid reading, and folded formats that are much easier to handle in the cockpit. Nautic Way offers both publishers to meet the needs of different types of sailors.
