First published in the 1950s Imray's Map of the river above Rochester has always been popular with boaters. There is no other large scale map of the non-tidal section of the Medway above Allington Lock. For the last twenty years the map had been published as part of a guide with a commentary by Derek Bowskill and now this brand new edition reverts to its early successful strip map format. The content has been revised and notes and photographs added by Dave Wise whose experience of navigating the river is as a canoeist. This new edition is printed in colour and packaged in an easy-to-use folded format.
