Tough Charts are fully waterproof and designed to be used on open or wet boats. They are A3 in size and spiral bound for convenience.
Each Tough Chart consists of around 15 main charts for a specific area as well as approach plans covering a number of popular harbours in the area. These are shown at larger scales. The main charts are based on the 1:75 000 scale charts of the area and are magnified for easier reading at speed.
There is a space to write notes on each of the main charts for quick reference. Tough Charts can be written on using either a pencil for temporary markings or a permanent pen.
Virtually Indestructable - throw it around, leave it wet or in the sunlight.
Convenient Size - light enough to hold in one hand.
