Battery charging is by way of a Mastervolt Mass Combi 12-2000-100 inverter/charger and battery condition is monitored with a Xantrex Link 10 battery monitor.

There is a master switch for start and service batteries.

Individual functions controlled by switch panel, including automatic fuses for all consumers with lights.

Working lights positioned throughout the vessel where appropriate, including flexible arm chart light and reading lights at berths. All wardrobes have lights.
