What this video covers
The crew of the 10-year-rebuilt fishing trawler *Brupeg* completes a multi-day coastal transit from Townsville to a naval shipyard in Cairns, Queensland, while commissioning a newly repaired autopilot system.2:01 After struggling with steering issues, the team integrates two donated autopilot units and replaces a faulty 24-volt solenoid with a 12-volt component to resolve power-delivery failures.29:58 The vessel navigates the Hinchinbrook Channel and crosses a shallow sandbar near a three-nautical-mile-long sugar-loading wharf by following specific lead lights that indicate lateral position via color-coded signals.22:44 During the passage, the crew monitors engine data through a fanless, heat-sink-cooled processor box running a RAID-1 system and tracks alternator output via a calculated shunt-current equation.3:47 The autopilot eventually functions reliably after the crew tunes the gain settings to account for the corrected hydraulic response.29:22 Proper voltage matching for solenoids is essential for consistent hydraulic steering performance.
