Old charts can still be used so long as they are accurate. Keeping them
up
to date with all the notices to mariners can be a full time occupation in
itself if you have a lot of charts, but its rewarding work. You can
download the notices to mariners digitally now, or if you have time, you
can
go to your local maritime office and sit there in luxury with a cup of
coffee and update your charts there.

Just don't get behind with the work. It is frustrating to start to catch up
with a heap of Notices in front of you and spend time plotting,say, the
position of a wreck obstructing a channel, and then find three or four
Notices later that it has been removed and you have to erase all your
previous work. Don't ask how I know that....
