What this video covers

Jakob Lang prepares his 47-year-old sailboat, Wolf, for a solo circumnavigation by upgrading the electrical system and deck equipment in Lelystad, Netherlands.1:14 He installs two 110-watt solar panels on the stern, managed by a Victron MPPT 100-15 charge controller, and adds a Victron SmartShunt to monitor battery state-of-charge via Bluetooth.3:31 The electrical refit also includes installing an AIS transponder with a GPS patch antenna, requiring careful routing of cables through the nav station and aft cabin to avoid existing 230-volt charging components.12:44 Deck maintenance involves having a sailmaker add a third reef to the mainsail and re-rigging the genoa into the furling system.10:13 Lang tests a mountaineering-based rope-climbing technique using two lines to ascend the mast for a rigging inspection.13:38 After troubleshooting a wiring conflict where the 230-volt charger inadvertently acted as a main battery switch, he successfully integrates the new monitoring system.16:30 These upgrades provide the power management necessary for long-term solo operation of the boat's autopilot and navigation electronics.
