The Coast Guard Navigation Center has implemented a small but important change to its website address. It is now https://www.navcen.uscg.gov, instead of http://www.navcen.uscg.gov. This change provides a secure, encrypted connection between browsers or other tools connecting to the Navigation Center website. It also provides authentication that you are unquestionably connecting to the Navigation Center website.
This change is a result of Office of Management and Budget (OMB) Memorandum M-15-13, Policy to Require Secure Connections across Federal Websites and Web Services, which requires that all publicly accessible Federal websites and web services only provide service through a secure connection (HTTPS instead of HTTP).
The Navigation Center is pleased to provide you with these secure services. Questions may addressed to our Web Services team via our Contact Us page at https://www.navcen.uscg.gov/?pageName=contactUs.
