In Part 1 we learned that it was inefficient, and often impossible, as well as potentially dangerous, to supply the high-load equipment, that so many cruisers seem to want, with a 12-volt system, regardless of the size of the battery bank, since the cabling and fuses simply won't support it.
And, further, that the solution to this problem is either to forgo all very high-current (amperage) gear, or select a boat with a 24-volt system—there are no other good options.
So let's look at that:
