manual navigation

Keep an eye on 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 critical.

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 convincingly at sea.

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

Deine Fragen / Unsere Antworte

What is the difference between a steering compass and a hand-bearing compass?
A steering compass is permanently installed and shows the boat's current course. A hand-bearing compass is held freely to read directions to landmarks or other ships and to plot them on the chart. For traditional chart navigation, you need both.
What is deviation and do I really need to worry about it?
Deviation is the deflection of your compass needle by magnets or steel on board – for example, by the engine or speakers. It is different on every boat and must be determined through a compass swing. Without a deviation table, your observed course may be off by several degrees.
How long are printed nautical charts valid and when do I need to replace them?
Nautical charts do not have a formal expiry date, but fairways, buoyage, and depths change. For busy areas, you should regularly check the edition for updates or buy a new edition at least every few years. Outdated charts in heavily buoyed coastal sections can become dangerous.
Can I use a regular parallel ruler on a nautical chart at a scale of 1:50,000?
Yes, the ruler itself is independent of the scale – you use it to plot courses and bearings regardless of the chart scale. For distance readings, you use the dividers and measure from the lateral latitude scale of the respective chart, as the scale varies there.
