*Ultimately every piece of equipment shares the sea water as an "earth"
Charging when connected to shore supply is via a Xantrex 20 Amp smart charger
Charging whilst under sail alone is available from the Aquair 100 towed water turbine, this provides a reliable 5Amps when sailing at hull speed.
The Aquair also has a wind turbine which supplies charging current when at anchor.
Additionally Bluesipp carries two small solar panels which we use to keep the batteries fully charged when we are away.
