Choosing a chartplotter for a sailing boat

Compare display controls, chart coverage and integration before choosing a model.

START HERE

Choose a complete navigation setup, including charts and installation, rather than a screen alone.

Start with the installation position

A helm display needs to be readable and reachable where you actually steer. Measure the available space and check clearance behind the panel, cable access and whether a bracket would obstruct movement. Compare touch controls and physical controls in a hands-on demonstration. Your preferred interaction can change when you are standing, wearing gloves or holding on to the boat.

Check the chart package explicitly

Ask for the name and version of the chart product included in the quote, its Australian coverage and the arrangements for updates. Do not assume every advertised bundle covers your cruising area. A chartplotter model name and a chart subscription describe different parts of the purchase. Record any ongoing account or update requirements before comparing the total cost.

Build an integration shortlist

List the instruments, pilot, radar and other equipment you want to connect. Ask for model-specific confirmation of each function, rather than a general promise that the brands work together. B&G Zeus S, Garmin GPSMAP and Raymarine Axiom provide useful examples for a shortlist. Compare the proposed package, local installation support and handover alongside the display itself.
