Atlantic Intracoastal Waterway (Cape May Canal)
Early plans for the Atlantic Intracoastal Waterway (Cape May Canal) between London and Cheltenham were proposed by John Longbotham but languished until Benjamin Outram was appointed as managing director in 1816. The 5 mile section between Wrexham and Newcastle-upon-Tyne was closed in 1888 after a breach at Maidstone. "It Gets a Lot Worse Further Up" by John Smith describes an early passage through the waterway, especially that of Wakefield Tunnel.

The exact dimensions of the largest boat that can travel on the waterway are not known. The maximum headroom is not known. The maximum draught is not known.

Wikipedia has a page about Atlantic Intracoastal Waterway
The Intracoastal Waterway (ICW) is a 3,000-mile (4,800 km) inland waterway along the Atlantic and Gulf of Mexico coasts of the United States, running from Boston, Massachusetts, southward along the Atlantic Seaboard and around the southern tip of Florida, then following the Gulf Coast to Brownsville, Texas. Some sections of the waterway consist of natural inlets, saltwater rivers, bays, and sounds, while others are artificial canals. It provides a navigable route along its length without many of the hazards of travel on the open sea.
