The installation quoteCompare autopilot installation quotes with a practical checklist covering drive sizing, wiring, steering work, commissioning, training and exclusions.4 min
Used-boat survey questionsAssess an autopilot on a used boat: identify the full system, inspect service records, request a suitable trial and budget for unsupported components.Installation
Installation: 4 guides
7 min
Calibration and sea trialCommission a marine autopilot through dockside checks, compass calibration and sea trials. Verify drive direction, rudder limits and steering response.6 min
NMEA 2000 integrationPlan NMEA 2000 autopilot integration: backbone layout, required data, mixed-brand limits, chartplotter control and connections to older marine networks.4 min
Your sea-trial logBuild a useful autopilot sea-trial record with boat loading, conditions, calibration results, steering observations, alarms and follow-up work.4 min
Before the retrofitPrepare for an autopilot retrofit by checking steering access, mounting structure, drive geometry, power supply, sensors and existing network equipment.Using it well
Using it well: 12 guides
6 min
Power consumptionEstimate marine autopilot power consumption by drive type. Calculate passage amp-hours and check the effects of steering load, cable losses and low voltage.7 min
Steering modes explainedUnderstand autopilot steering modes: Auto heading hold, Wind, Track, Nav, No Drift and fishing patterns. Check required inputs and when to take manual control.6 min
Alarms and failuresUnderstand marine autopilot alarms for off-course steering, overload, low voltage and missing data. Review failure responses, spare parts and backup planning.7 min
Autopilot troubleshootingSymptom by symptom autopilot troubleshooting: S-turns, sluggish steering, drive alarms, heading errors, network dropouts, low voltage and wind mode faults.6 min
Autopilot remotesWired and wireless autopilot remotes, plotter control and phone apps: what they add on a shorthanded boat, what fails, and what to practise before trusting one.6 min
Autopilot tuningWhat rudder gain, counter rudder and response actually do, how adaptive pilots reduce the fiddling, and a sea-trial method for tuning your own boat.7 min
Batteries, solar and autopilotsWork out what your autopilot really uses, build an amp-hour budget for a passage, and size batteries, solar and charging for Australian conditions.4 min
The watch handoverUse a structured autopilot watch handover: active mode, target heading, next waypoint, alarms, steering behaviour and the route back to manual control.4 min
Night display setupPrepare your helm for night use with readable autopilot modes, controlled screen brightness, accessible standby controls and a clear alarm routine.4 min
Before Track modeCheck route legs, chart scale, cross-track limits and waypoint turns before letting a marine autopilot follow navigation data from your chartplotter.4 min
Sail balance firstSeparate sail-balance problems from autopilot tuning: observe helm load, reduce unnecessary steering demand and record one controlled change at a time.4 min
An unfamiliar helmUse this charter-boat autopilot briefing to locate standby, understand supported modes, check restrictions and practise takeover before departure.Safety and rules

Where should a first-time autopilot owner start?
How marine autopilots work, then Choosing an autopilot, then Autopilot calibration and sea trial. After that, the safety guides before the first overnight passage.
Are the guides brand-specific?
No. They explain the concepts and name products where the difference matters. Product-specific detail lives on the autopilot pages.
