Imray Y Series Charts

Imray Y Series charts give large-scale coverage of UK harbours, rivers and estuaries, for detail that a C Series passage chart cannot show. They come in two sizes: standard charts at 640 × 900mm, and small-format charts at A2 for smaller chart tables and the cockpit. Both are printed on Pretex, a synthetic paper that handles spray and damp conditions, and come folded to A4 in a plastic wallet. Many of the small-format charts are also available laminated.

Coverage runs from the Wash, the Suffolk and Essex rivers and the Thames Estuary along the south coast through the Solent, Poole Harbour and the West Country to the Isles of Scilly. There are also charts for Milford Haven, the Isle of Man, the west coast of Scotland from Gigha to the Sound of Mull and Loch Linnhe, and Gibraltar. The charts draw on official UKHO data with additional detail from Imray's own contributors, and use WGS 84 datum with metric depths.
