Notices to Mariners
A new issue of Notices to Mariners (NtM) is published every fortnight.
The publication features recent nautical information of importance to the navigation sector, together with supplements and corrections to the nautical charts. This nautical information is extremely divers. It can include changing buoys, dangerous situations, changed laws and/or guidelines, recent wrecks and/or obstacles, and so much more.
This information must be applied directly on the nautical charts. These updates guarantee seafarers that their nautical charts always show the most recent information.
