Developed in conjunction with the Royal Yachting Association, 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.

What does a Tough Chart Contain?
Each Tough Chart numbered SC5901 to SC5910 and SC5915 consists of around 20 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 Standard Nautical scale charts of the area and are magnified for easier reading at speed. Though Charts numbered SC5911 to SC5914 offer coverage of the rivers and harbours of a geographical area. The charts are produced at various scales.

Can I write on it?
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 which can be removed with a non abrasive eraser or using a permanent pen for permanent markings.

What about keeping it up to date?
Even though they are waterproof, Tough Charts can be updated using Notices to Mariners (NMs). Textual updates can be applied directly to the product. To obtain a waterproof block NM, please e-mail CustomerServices@ukho.gov.uk stating your requirement.
