What this video covers
After six weeks of maintenance in Townsville, the crew of a Prout Ltd. Snowgoose 37 Elite completes a hull refit using Coppercoat and upgrades the windlass electrical system.16:41 To activate the Coppercoat, the crew burnishes the hull with 400-grit sandpaper to expose the copper particles through the epoxy layer.1:15 During sea trials, the windlass performs poorly under load due to significant voltage drop across a 6-meter run of 25mm² cable.6:28 The crew replaces this with 50mm² cable, using a manual lug crimper to secure new connections, which restores sufficient torque to the motor.7:05 Additionally, the crew installs a new watermaker membrane, achieving a water quality of 350 parts per million.14:45 Following these repairs, the vessel departs Townsville for a 10-day coastal hop toward Thursday Island, avoiding a 3.5-meter swell outside the reef.16:38 The crew plans to navigate through shallow waters with coral heads and sand shoals before eventually crossing to Indonesia.17:52
