There are not many feasible techniques to supply electrical energy on board
of a sailing yacht, which do not dependent on shore-bound supplies or facilities.
Especially when moored in remote bays for days or even weeks, the energy supply of a
sailing vessel may become a problem.
The amount of electrical energy that can be stored in the on-board batteries is rather
limited and will be exhausted after a few days without recharging the batteries.
The advantage of wind generators is that they are relatively cheap, reliable and robust and they are capable of generating electrical energy without the need of any external supplies. Also solar panels can be used to make a sailing yacht self-supporting in terms of electrical energy supplies. Although solar panels have a less favorable cost to power ratio, they are very reliable and require almost no maintenance.
The power system on small vessels is usually a low-voltage installation (typically 12V). This implies high currents in the cables used for the power distribution from the source to the different electrical loads. The efficiency and safety of such a high-current network strongly depends on properly sized cables both in length and diameter. These sizes determine the parasitic resistance of the network that may dissipate a large amount of energy if not planned and sized correctly to support the required energy flow to the connected equipment.
