Imray charts set the standard for the leisure sector with award-winning cartography which features our distinctive colour scheme, coloured light sectors and fine overprinted latitude and longitude grids to make plotting easier.
Our charts, based on up-to-date official surveys and receive continual attention and amendment by our staff, who monitor corrections to ensure that our charts are always as correct as possible when dispatched.
Corrections
Charts are correct to the date of printing and are supported by corrections which may be downloaded from this web site until a new edition is compiled. Once a new edition has been published the old edition cannot be corrected, is regarded as being unsafe for navigation and should be replaced.
Correction notices for individual Imray charts may also be downloaded from these pages.
Waterproof paper
Most Imray charts are published on Pretex, a partially synthetic paper, which folds well and is durable in damp conditions. It may be drawn on in both soft pencil and ballpoint pen.
Imray charts are normally published to an approximately A4 fold format and supplied in robust PVC wallets. Flat sheets are available on request.
All Imray charts are now based on WGS 84 datum. Apart from some of the Imray-Iolaire charts of the Caribbean Sea, all are metric.
Every chart includes details of the datum and projection on which it was based, to allow it to be used safely with GPS navigation systems.
British Admiralty Charts, Admiralty Leisure Folios, Netherlands 1800 series charts, chart packs from the Croatian Hydrographic Office, the Netherlands, and NV and Delius Klasing in Germany are all available to buy from this web site. Most of these are available from stock but they can also be supplied to order.
