NaviBoss guides are written and checked by maritime industry experts, masters and deck officers. Each one is built from the same data the planner uses, dated, and rebuilt when that data changes. Spotted something wrong? Tell us on the feedback board.
A planning aid, not for navigation. The official in-force list from the NAVAREA coordinator, your NAVTEX and SafetyNET receivers and the latest Notices to Mariners always come first.
