Personal Flotation Devices (PFDs): A Canadian approved PFD is designed to keep you afloat in the water. PFDs were designed for use in recreational boating and are generally smaller, less bulky and more comfortable than lifejackets.
The Erie Canal, in New York state (shown below), was 360 mi (580 km) long, and connected New York with the Great Lakes via the Hudson River. Locks were built to overcome the 571-ft (174-m) difference between the level of the river and that of Lake Erie.
The Erie Canal is an artificial waterway that connects the Hudson River to Lake Erie. This historic waterway, first completed in 1825, is one of the most important projects in the development and success of New York and the United States.
