What this video covers

The crew of the sailboat Uma removes their single Oceanvolt electric motor and servo prop to install a dual-motor system.0:11 They drain the oil from the skeg, unbolt the unit, and grind out the original fiberglass mounting bed to seal the hull.1:17 To optimize hydro-regeneration, they plan to mount two new servo props symmetrically on either side of the hull.14:29 This requires precise alignment in three-dimensional space to ensure the propeller axes remain parallel to the boat's centerline while also matching the curvature of the hull for laminar water flow.15:56 The crew uses a laser level to align the new mounting beds before bonding them with epoxy.17:48 They perform the fiberglass layup for the new mounts simultaneously from the inside and outside of the hull to ensure structural integrity.27:45 The project aims to double the vessel's power generation capacity while sailing.14:14
