Electricity on Board
(And other off-grid applications)
Revision 9
May 2007
Electricity plays an increasing role on board yachts. Modern navigation and communication equipment
depends on it, as well as the growing list of household appliances that are taken on board.
This is the concept text for a booklet about electricity on board small and large yachts. The intention of
the book is twofold:
Firstly I try to cover in depth a few matters that over and again are subject to discussion and
misunderstanding, such as batteries and management of batteries, or electric power consumption of
refrigerators, freezers and air conditioning.
My second intention is to help designers, electricians and boat owners to decide on how to manage and
generate electricity on board. Several new products and concepts have substantially broadened the
range of alternatives here.
Together with some unavoidable theory, I use examples of small and large yachts to clarify the
consequences of choosing one alternative or another. The consequences are sometimes so unexpected
and far reaching that, writing it all down, I have also helped my own understanding!
