Update Your Chart

Many mariners understand the importance of having charts onboard but it's just as important to ensure your charts are up to date. If a buoy has changed or there is a new obstruction, you need to know about it before you encounter it, not after. CHS regularly updates charts and it's essential you have the latest updates for safe navigation.

There are different ways to find out about chart updates depending on the type of chart you have.
