What this video covers

Installing a Garmin Reactor 40 autopilot on the 48,000-pound displacement vessel Athena involves mounting a drive unit to the rudder stock, installing a course compute unit (CCU) in the forward cabin, and configuring the system via a GHC20 display and ActiveCaptain app.1:29 Because the standard rudder feedback sensor was incompatible with the drive unit placement, a GR-F10 sensor was installed on the stainless steel tiller arm.4:29 The dockside configuration wizard successfully calibrated the rudder limits, though sea trial calibration remains pending due to 25-knot winds.9:37 Additionally, the project includes integrating a 185A high-output alternator with an external regulator from Ocean Planet Energy, requiring communication with the boat's battery management system (BMS).12:22 Engine starting issues caused by a faulty MDI box currently prevent full testing of the alternator charging system.15:44 The crew plans to replace the MDI with manual switches to ensure reliable engine operation and monitoring before departure.16:20
