We endeavour to sell only the latest versions of nautical charts that include the most recent updates.
Imray nautical charts use the meter as reference unit.
All Imray charts are now based on the WGS 84 reference system. Except for some Imray-Iolaire charts of the Caribbean Sea, all charts are in the metric system. Each chart includes reference system details and projection on which it is based, in order to be entirely safely used with GPS navigation systems.
Familiar to navigators, nautical charts have undergone intensive evolution over time. Whatever chart is used, precautions must be taken for safe use.

The paper:
Imray has adopted Pretex, a support whose main characteristic is its resistance to use in humid conditions (rain, sea-spray), while still enabling easy writing and erasing of personal navigation data (position and route plotting, etc.).
This support is latex coated paper, which makes it highly resistant to folding, even when wet. This water resistance is not unlimited but provides the chart with satisfactory durability.
Imray charts coverage is divided into several series:

Reprint and updates:
Based on official update surveys, Imray charts are continuously overseen by the publisher, who monitors corrections, so that the charts are always as accurate as possible and ready for delivery.
Nautical charts are corrected up to the printing date; updates can be downloaded from the Imray website until a new edition is published. Once a new edition has been published, the previous edition cannot be corrected; it is considered dangerous for navigation and must be replaced.
On this edition the latest depth surveys have been applied. The chart of the River Dart has been reschemed to show larger scale coverage of Kingswear and Dartmouth. Harbour plans of Polperro and a larger scale (1:9000) plan of Salcombe are included for the first time. The harbour plan of Padstow has increased coverage to show greater detail of the approach.
Chart 2400.8 (Start Point to Fowey) has been reschemed to include the approaches to Dartmouth. The chart scale remains the same. For this edition tidal stream information is included. There has been general updating throughout
Individual sheets of this atlas will no longer be sold separately. However, 1st edition charts Y43, Y44, Y45, Y46, Y47, Y48, Y49 and Y50 will be published shortly. These replicate current charts 2400.16, 2400.5, 2400.13, 2400.7, 2400.12, 2400.11, 2400.3 and 2400.14 respectively. These form part of our 'small format Y chart series' that mirror coverage of charts from the corresponding atlas and printed A2 size. For details of these please see their individual web page.
