A summary of the guidance is captured below, but for the entire Bulletin, go to this address https://www.pacificarea.uscg.mil/Our-Organization/Northwest-District/District-Staff/dp/dpw/notices/ and look for the Navigation Rule 10 link.\n\nRule 10 of the Navigational Rules of the Road mandates specific conduct while within Traffic Separation Schemes (TSS) to promote safe navigation of vessels and reduce the possibility of collisions, especially in areas of high vessel traffic. If using a TSS, you must: Proceed in the appropriate traffic lane in the general direction of traffic flow for that lane; Keep clear of a separation zone or separation line, unless you must cross it; Normally join or leave a traffic lane at the termination of the lane, but when joining or leaving from the side, do so at as small an angle to the general direction of traffic flow as practicable. Vessels of less than 20 meters in length or sailing vessels shall not impede the safe passage of a power-driven vessel following a traffic lane. Fishing Vessels are permitted to fish within the separation zone, as to not impede the safe passage of any vessel following a traffic lane. A vessel shall not use a traffic separation scheme when it can safely use an adjacent route. A vessel other than a crossing vessel or a vessel joining or leaving a lane shall not normally enter a separation zone or cross a separation line except in cases of emergency to avoid immediate danger. For Additional Information, Contact VTS on VHF channel 5A in the Strait and North of Everett, channel 14 south of Everett, or by phone at (206) 217-6152 for information on vessel movements. Contact USCG Sector Puget Sound Command Center at (206) 217-6002 to report unsafe operations or conditions within the port.","COORDINATES_JSON":"{\"type\":\"Point\",\"coordinates\":[-122.78621,48.18487]}","COORDINATES_TYPE":"Point","DECIMAL_LONGITUDE":-122.78621,"DECIMAL_LATITUDE":48.18487}},{"type":"Feature","id":50324,"geometry":{"type":"Point","coordinates":[-90.91300999999999,30.102630000000033]},"properties":{"ESRI_OID":50324,"MSI_UID":50324,"ATU":8,"TITLE":"New Orleans Harbor - New Orleans To Baton Rouge/General/MSIB","STATUS":"Approved","MSI_GROUP":"General","SUB_CATEGORY":"MSIB","TYPE":null,"WTRW_UID":100119138784,"MRN":"urn:mrn:iala:wwy:us:navIV:dis8:secneworlexcecozon:secneworltersea:secneworlsublanact:soupas:heaofpastoneworl:neworlhar:neworltobatrou","WATERWAY_NAME":"New Orleans To Baton Rouge","CREATE_DATE":1785763984000,"MODIFIED_DATE":1786371256000,"BEGIN_DATE":1785715200000,"END_DATE":1793491199000,"DESCRIPTION":"MSIB Vol XXVI Issue 027 - Mississippi River - Low Water Safety Advisory --- The National Weather Service forecasts low river stages.
