Navigation & Audio

Which system is right for your boat?

For day-trippers in familiar waters, a compact chartplotter with an integrated echo sounder is often sufficient. Blue water sailors and motor yachts with multiple stations, on the other hand, benefit from a networked NMEA 2000 bus, which allows chartplotters, autopilots, AIS transponders, and wind sensors to share data. Before buying, consider which devices you already have and which ones you want to add in the future – this saves expensive duplicate purchases.

Transducers, Converters, and Compatibility

A chartplotter without a suitable depth transducer or an AIS receiver without a connected VHF antenna is of little use. Pay attention to hull-mounted or in-hull versions for the echo sounder transducer and check whether your existing device supports the new device's converter. Many manufacturers block their protocols – open NMEA 2000 products offer more flexibility here.

Audio Systems in the Cockpit

Marine speakers and amplifiers differ from home electronics due to UV-resistant housings, sealed membranes, and corrosion-resistant terminals. Pay attention to the protection class: IP65 protects against splashing water, IPX7 allows for brief submersion – relevant for speakers in spray areas. Connection cables in the bilge area should always be secured with crimp connectors and corrosion protection spray.

Care and Longevity

After the season, rinse displays with clear water, treat connectors with contact spray, and protect chartplotter displays from UV radiation if the boat is laid up for an extended period. Don't forget firmware updates – they close security gaps and improve map compatibility.
