At AnglingCharts I produce cruising charts & fishing maps. I survey lakes and create GPS and paper charts - purely as a non-commercial venture. It's a pastime, much the same as fly fishing is a pastime. Expensive, time consuming, and occasionally very satisfying. It also seems to be becoming quite a geological and archaeological adventure.
On this website you'll find a growing collection of charts which I can either let you have completely free, or for a small price. There are paper charts of well known boating & fishing lakes, iPad Charts
, GPS charts , some free downloads, Android charts
, lots of interesting "stuff", including wrecks and amazing sidescan sonar imagery, tutorials to help you make your own charts, and The Lough Corrib Chart Book
