On the contrary. I have bought a dominant portion of my charts over the years used and out-of-date. Many (maybe all) shipping lines replace charts regularly with the latest and their discards are in perfect shape. A quick update from Notice to Mariners and they're definitely good enough for cruising sailors.I Don't think you will have any luck selling out of date charts if i were you i'd donate them to a Sailing school for training purposes
A lot of the charts used even by shipping lines today are predominantly made up of observations by Cpt James Cook!!!How old is out of date? 2008 doesn't seem all that old to me. How often do you all buy new charts?
