A Notice to Mariner is issued for the purpose of providing permanent navigation information—generally this information will result in a chart correction.
A notice may be marked as Temporary (T) if the information will remain valid only for a limited time.
Advice notices will cover short term navigation advice and may include information on fireworks displays, aquatic events or similar.
If at any time you see something on the water that you think may pose a hazard to navigation, please contact MAST so that a determination can be made as to whether a Notice to Mariners is necessary.
