Machinery & Systems
Propulsion, running gear, electrical, electronics and the dive-specific systems that keep a liveaboard earning. Engine and gearbox overhaul, cooling and fuel systems, shaft alignment and stern gear, switchboards and battery banks, bonding and stray-current investigation, navigation and communications, and breathing-air compressors and nitrox plant.Most of this work can be done afloat at anchorages around Waisai, the Dampier Strait, Gam, Kri and Misool, which is what allows an operator to base in Raja Ampat and still keep downtime measured in days. The binding constraint is parts lead time, not skill, and these notes explain how to plan around it.
