What this video covers

The crew of the 36-foot sailboat Uma installs two Oceanvolt sail drive flanges into the hull to facilitate a twin-motor electric propulsion system.5:21 To ensure proper epoxy curing in cold temperatures, the crew seals the work area with tarps and uses a 15-kilowatt propane heater to maintain ambient warmth.0:34 After cleaning the mounting surfaces with acetone, they align the proprietary flanges using a laser to ensure precise positioning before bolting and sealing them with SikaFlex.5:29 The twin-motor configuration aims to increase power generation through hydro-regeneration, improve docking manoeuvrability by allowing differential thrust, and provide system redundancy.16:37 By transitioning to a fully electric setup, the crew intends to eliminate all onboard fossil fuels, including diesel, propane, and petrol, while balancing increased electrical loads with expanded solar, wind, and regeneration inputs.11:59 The installation of the motor beds marks the completion of a structural phase, allowing the crew to proceed with interior cabinetry and final hull fairing.18:40
