What this video covers

The crew of the 10-year-rebuilt fishing trawler *Brupeg* performs sea trials and maintenance while transiting the Queensland coast. The primary technical challenge involves troubleshooting an intermittent autopilot system that functions at anchor or low speeds but fails to command the hydraulic rudder system under load. The crew monitors roll angles, engine performance, and fuel consumption—averaging 9.6 knots at 1,300 RPM with a fuel burn of 31 liters per hour—while testing a new dashboard display that tracks pitch, roll, and fuel filter differential pressure. To improve hull efficiency for future modifications, they collect motion data to assist a naval architect with computational fluid dynamics modeling. Navigation tasks include transiting tidal gaps between islands, where eddies cause the vessel to yaw, and planning a compass calibration maneuver in the sheltered waters of Airlie Beach. Additional maintenance includes replacing seized door hinges and greasing bow roller fittings. The crew concludes that course-over-ground data is more useful for their navigation display than heading data.
