Navigation triangles & rulers

Keep track of your course, data, and safety

Navigation and communication are crucial for safety and overview. Interfaces like NMEA 2000/0183, suitable sensors, and correct voltage are decisive.

Many systems can be expanded step by step – from a simple display to a fully networked system.

This way, you get technology that truly supports you and performs well at sea.

Discover variants, materials, and designs built for maritime use. This way, you'll find equipment that remains reliable on board – season after season.

Deine Fragen / Unsere Antworte

Which degree scale do I need for marine chart navigation with German coastal charts?
Most German coastal charts from the BSH (Federal Maritime and Hydrographic Agency) are published at a scale of 1:50,000 or 1:100,000. A set square with a 360-degree full-circle graduation and a nautical mile scale for these scales covers the most common applications. Look closely at the scale before you buy – not every set square fits every chart scale.
Is a parallel ruler or a set square the better choice for a small cockpit?
Set squares are often more practical in confined spaces because they don't require the incremental repositioning of a parallel ruler and can be read directly from the compass rose. Parallel rulers require a stable, flat surface and some practice to prevent the line from jumping when moving them.
Does acrylic scratch easily, and can I still save a ruler that has become opaque?
Acrylic does scratch easily with sand or coarse cloths. Light scratches can be polished out with plastic polish, but strong clouding caused by solvents is permanent. It is best to use soft microfiber cloths and clear water for cleaning.
Can I also use navigation triangles on a stainless steel or laminate chart plotter table?
In principle, yes, but on smooth surfaces, triangles without an anti-slip base can easily slide – especially in choppy seas. Triangles with rubber nubs or a cork base on the table can help here.
