Frequently Asked Questions
What are chart brushes used for?
Chart brushes are designed to remove eraser crumbs, pencil shavings, and dust from nautical charts. Keeping the chart surface clean helps navigators read course lines, depth soundings, and annotations clearly, reducing the risk of reading errors during passage planning or position fixing.
Can I use a chart brush on electronic chart displays?
For electronic charts, use a soft microfiber cloth or a specialized screen brush. A traditional chart brush with natural bristles is intended for paper charts and drafting surfaces. Using it on electronic displays may scratch the screen.
How should I clean my chart brush?
Simply tap the bristles gently against the edge of a waste bin to remove collected debris. For deeper cleaning, wipe the bristles with a dry, lint-free cloth or a small amount of mild soap, then allow them to air-dry naturally. Avoid soaking the wooden handle.
Why is a chart brush required on board ships?
Paper nautical charts remain an important part of safe navigation. A chart brush keeps charts neat and legible, which supports accurate voyage planning and compliance with ISM and STCW best practices. It is a standard item in the nautical equipment inventory of many vessels.
