It rises in the St. Johns Marshes near the Atlantic coast below latitude 28°00'N., flows in a northerly direction and empties into the sea north of St. Johns River Light in latitude 30°24'N. The river is the approach to the city of Jacksonville. Deep-draft vessels go as far as just below the Main Street Bridge. Southward of the Jacksonville bridges, commercial traffic is light and barges may be present occasionally. Many pleasure craft navigate this part of the river, usually going only as far as Sanford, though small boats have navigated the river as far as Lake Washington, 188 miles south of Jacksonville.  \n(3)  \nIntracoastal Waterway  \n(4) The Intracoastal Waterway crosses the St. Johns River at nearly right angles about 5 miles above the mouth, at about 30°23 . 1'N., 81°27 . 8'W.  \n(5) Jacksonville has expanded by consolidation to include most of Duval County and is now the largest city in the United States in terms of area; its extent along the St. Johns River is from the ocean to the town of Orange Park on the west side of the river and to Julington Creek on the east side. Most of the marine terminals are on the west side of the river. The deepwater port is the largest on the east coast of Florida. It is a major southeastern bulk-handling, distribution and railroad center. General, automobile and bulk cargoes are handled, and Jacksonville is a leading southeastern container port. The principal exports are paper products, phosphate rock, fertilizers, chemicals, citrus products, naval stores, automobiles, scrap metal, feed and general cargo. The principal imports are petroleum products, coffee, iron and steel products, limestone, pulpwood, cement, automobiles, lumber, chemicals, alcoholic beverages and general cargo.  \n(6)  \nCaution  \n(7) With the exception of north-easterly or northerly winds, the prevailing current in this area is northerly, felt until well inside the 10-fathom curve.  \n(8)  \nFish havens  \n(9) Numerous fish havens are eastward of the entrance to St. Johns River; the outermost is about 31 miles eastward of St. Johns Light.  \n(10)  \nProminent features  \n(11) St. Johns Light (30°23'10\"N., 81°23'53\"W.), 83 feet above the water, is shown from a white square tower on the beach about 1 mile south of St. Johns River north jetty. A tower at Jacksonville Beach is prominent off the entrance, and water tanks are prominent along the beaches southward of St. Johns Light.  \n(12)  \nCOLREGS Demarcation Lines  \n(13) The lines established for St. Johns River are described in 33 CFR 80.723, chapter 2.  \n(14)  \nSt. Johns River navigational guidelines  \n(15) After consultation with the Jacksonville Marine Transportation Exchange, JMTX, the Coast Guard Captain of the Port has developed certain guidelines to enhance safe navigation in the St. Johns River. It is recommended that all vessels, particularly those that must navigate in the channel because of draft restraints, strictly adhere to them. Nothing in these guidelines shall supersede or alter any applicable laws or regulations. In construing and complying with these guidelines, regardshall be had to all dangers to navigation and collision and to any special circumstances, including the limitations of the vessels involved, which may make a departure from the guidelines necessary to avoid im","cbCaivEj7lckc46N","https://ap.wps.com/l/cbCaivEj7lckc46N","pdf",474957,"English","# St. Johns River Overview\n# Intracoastal Waterway Crossing\n# Jacksonville Port and Cargo Overview\n# Caution and Fish Havens\n# Prominent Features and Lights\n# COLREGS Demarcation Lines\n# Navigational Guidelines for St. Johns River\n## General Provisions and Vessel Definitions\n## Inbound Vessels Timing (Sea Buoy to Main Street Bridge)\n## Outbound Vessels Timing (Main Street Bridge to N.B.
