What is an Admiralty Tough Chart?
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 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.
