American canal boats were built to standards as unique as their canals. On the Delaware Canal, a preferred wooden “hinge” boat built to Lehigh Coal and Navigation Company specifications measured 87.5 feet long, 10.5 feet wide, and 7.5 feet tall and carried up to 100 tons of cargo. Private boatyards built and repaired boats along the Delaware Canal at Uhlerstown, Erwinna, Upper Black Eddy, Point Pleasant, New Hope, and Bristol, while major company-owned boatyards operated in Weissport and Laury's Station on the Lehigh Navigation. Captains liked hinge boats because their two sections could be separated by removing center connecting pins, allowing them to turn in the narrow Delaware Canal, haul two types of freight, and travel on the inclined planes of New Jersey's Morris Canal without transferring loads. In 1833, Canal Commissioners established passing rules that gave unloaded boats the right-of-way when two boats met: the loaded boat moved to the side opposite the towpath and stopped its mules so the tow line would sink to the canal bottom and the lighter boat could pass over it. Even so, difficulties sometimes arose, especially when a faster boat could not pass a slower one, because money depended on loads and time. Flora Henry recalled one day when her father grabbed both the driver and captain and threw them into the canal, while her dog Buster seized one captain by the seat of the pants and tore them off, leaving the man's wife to steer while he went into the cabin to put on another pair after acting fresh.
