they’re serving. High-end charge controllers
have the ability to take almost any source
of energy (shore power, alternator, solar, or
wind) and turn it into the correct output for
the battery bank.
By design, these systems connect many
components that need to work together,
which generates a wealth of information.
Some gear-head boaters, like yours truly,
would like as much information as possible;
others just want the silence. Make sure the
option you choose has the ability to hide or
display the information you want.
Part and parcel of the responsibility
of these new sys-
tems is safety. The
user must never
come into contact
with these volt-
ages. The key is
to build it right
in the first place
and never need to

The world of standards is catching up with
the technology. The American Boat & Yacht
Council published a document titled “TE-
30 Electrical Propulsion Systems” in 2009,
and the ISO and IEC international standards
groups are working on a document as you
read this. When researching one of these
innovative products, ask, “To what standard
was this product designed and built?” Some
builders are ahead of the marine standards
curve and building to an electric train/light-rail specification; others pay close attention
to the automotive market.
The hybrid boat market is gaining traction. At the Marine Equipment and Trade
Show (METS) this year, more and more
companies were displaying systems, system
components, and battery technologies that
were suited to the propulsion market. The
decision to invest in a hybrid boat must take
into account your boating preferences as well
as the technical advantages and maintenance
issues. The market is substantially supplying
and backing this exciting technology. The
more time passes, the more players will enter
the arena, the more the prices will come
down, and the more choices you’ll have.
