e all know the story. You've been on the water since
early morning, you've managed a tricky navigation
through unfamiliar waters, but you've finally arrived!
Drop the hook in a spectacular, quiet bay, enjoy a lovely dinner
and a bottle of wine, then close your eyes and enjoy a peaceful
night gunkholed under the stars, to fall asleep to the gentle serenade of the crickets and the haunting cry of the loon. Except
you can't hear the crickets, you can't hear the loons and you can
barely hear your own thoughts over the incessant hum of that
bloody generator.
There's no way you're shutting off the air conditioning on such
a hot summer's night. But there's also no way you're ever going
to sleep with all that noise. Sound familiar? Trust me - you're in
good company.
From the smallest open fishing boats to the largest luxury
yachts, the heart of any vessel on the water these days is its DC
power system because, to put it succinctly, without power nothing else works. The stereo, the air conditioner, the TV, the GPS
- nothing. As we continue adding more and more high-tech

goodies to our boats, we are ever more reliant on a steady flow of
power to make them all work.
It is this ever-increasing need for power that has put unprecedented demands on marine electrical systems. Although individual products may be increasingly energy efficient, the simple fact
we keep adding more and more of them onboard tends to cancel
out any gains we might have made - especially since we seem to
want to run them all at once. So whether they draw power continuously like our radios and MFDs, or suck it up in surges the
way bow thrusters, windlasses and galley appliances do, the net
result is the same - our demand for electrical power is enormous,
and incessant.
The evidence can be seen below the deck of any modern boat.
Where cruising yachts were once almost universally powered by
simple 12-volt systems, today we're seeing 24-volt systems and
36-volt systems more and more often. Yet even those are sometimes challenged to keep everything humming as it should.
Little wonder then that serious cruisers are among the leading
champions of new lithium-ion battery systems coming to market.
