I am hoping to take part in the around Ireland event in 2013. I am looking at purchasing charts for the event. Has anyone used the Imary CD rom charts? I am looking at ID 30. I am wondering if the chart can be printed from the computer onto a paper format and if so will it still have the lot and long at the edges. i.e. if I purchase the CD rom will I still need to purchase the paper charts or can i use the CD rom?
