BNM Distribution Modernization Project

The Navigation Center Broadcast Notice to Mariners Distribution Modernization Project is a Coast Guard-wide effort to format and distribute MSI which is optimized for modern electronic systems such as cell phones and electronic chart systems. This system now covers the entirety of District 5, delivering MSI (such as Broadcast Notice to Mariners) to email and the web through an RSS service. Through, a free online subscription service, mariners can subscribe to selected “Topics" based on geographical areas to receive information that has traditionally only been available through VHF-FM marine band radio. This change greatly enhances the mariner’s ability to plan before and during transit.
This system benefits the safety and efficiency of the maritime community by providing additional methods to pull down, receive, and organize pertinent information. Keep in mind, this message format does not replace voice broadcasts.  Always monitor VHF Channel 16 for official message dissemination.
Format changes will be introduced periodically, and the frequency of updates will increase – these changes will be documented on this webpage as well as any further changes to the Navigation Center MSI System in general.

To subscribe to “Topics” or view the RSS feeds please follow this link: Subscription Services / RSS
