Repowers, overhauls, shaft and bearing work, laser-aligned to tolerances the boat was probably never built to in the first place.
Engines and gearboxes removed, rebuilt or replaced, with beds reworked to suit rather than shimmed.
Shafts trued, bearings renewed and the whole line laser-aligned with the yacht afloat.
Hydraulic systems, rams, fins and gyros serviced, replaced and proven under way.
Consumption, noise and vibration measured against what was promised at survey.
