Nautical Charts

Trent-Severn Waterway National Historic Site

The Navigation Safety Regulations (2020) require boaters to carry the most recent editions of charts, publications and documents published for your area of operation. These items may not be necessary if the person in charge of navigation has enough knowledge of shipping routes, lights, buoys and marks, navigational hazards, as well as normal navigational conditions and weather patterns to ensure safe navigation.

Most charts are marked with latitude and longitude coordinates based on horizontal datum NAD83, however some charts may be based on NAD27 (remember to adjust your GPS unit accordingly).
