Day Skipper - Part 4 - Chart
corrections
Unless you replace your charts every time you use a boat, it is important
to keep them corrected and up to date. The Hydrographer of the Navy issues
Weekly Notices to Mariners, which add up to more than 4,000 amendments
a year. These are condensed into Small Craft Edition of Admiralty Notices
to Mariners, which concentrates on those that are particularly interesting
to yachtsmen, and can be obtained by subscription.
MBY's Chart Update, edited by Dick Hewitt (December issue MBY), offers
a concise list of amendments for popular yachting areas. If you are in
any doubt about the last correction on a chart, look at the bottom left-hand
corner at the 'Small corrections' note. This lists the year and corrections
that have been appended to the chart. If you are using someone else's
chart, this is a good indication of how up to date the chart is.
