Pre-season inspection of your boat's electronics

Fitting-out guides cover the engine, hull and antifouling. Almost none go deep into the electrical and electronic side, which is precisely the part that fails most quietly, just when you need it.

Battery and power

After months without heavy use, the battery is the first thing to fail and the last to be checked properly. It's not enough that it starts the engine: check the terminals, the real state of charge and whether the charging system works correctly.

Wiring and connections

Salt, damp and movement degrade wiring and connectors faster than on land. An intermittent fault in a unit may come from a deteriorated connection, not the unit itself.

The full checklist

  • GPS and chartplotter: charts up to date and card read without errors
  • Radar: no new interference or blind spots
  • VHF and AIS: a real test call, not just checking it powers on
  • EPIRB: battery and hydrostatic release expiry dates
  • Alarms and bilge sensors: test that they actually trigger
  • Automation: check the scenes still respond

A check doesn't replace full maintenance

This checklist doesn't replace full preventive maintenance, but it's exactly what our pre-season electronics check covers.
