Both would be the goal.....zero emissions. They have some very good
re-generative systems and nickel-metal hydride and lithium-ion
batteries. The boat would have plenty of room for some huge battery
banks.

You could probably supply house loads with just solar panels and/or
wind generators. However I'm a bit skeptical about standby
propulsion regardless of battery banks size. By the time you drag
props that are big enough to capture significant power, you'd be
adding enough drag to considerably slow the boat. On the other hand
if you are just looking for talking points in a marketing plan, what
the heck.

The GREEN MOTION system eliminates fossil fuel used by sailing
yachts in any way. Electrical energy is generated with the system and is
stored in batteries (lithium Iron Phosphate are optional). It will
generate sufficient energy to be used for propulsion, hot water, cooking
and all electrical equipment and navigation on board. When batteries are
fully charged or high speed is required (race) the lifted Motogens
eliminate the drag from the propulsion system and this increases the
speed of the yacht (between 5 - 15%).

Retractable Motogen
The electric retractable Motogen is new, light
weight, extremely efficient and better than any propulsion system ever
designed for yachts. Usable in all sailing yachts from 30 to 90 ft (9-30
m): monohull, catamaran or trimaran). Installation can be made inside
the hull in a monohull or on a retractable arm for multihull. 5 years of
extensive testing has been done with a ‘proof of concept’ sailing in
excess of 10.000 Nm.

OK, it's a cat, and not up to Joe's cargo work, but some of the
technology must transfer. I don't fancy the cost of those li-ion
batteries though... but they do handle huge charging loads, charge
quickly, and deliver their full capacity, not just a small percentage of
it.

The idea of a boat that needs no fuel of any kind, other than that
required to sustain the crew, does appeal. No diesel for *anything*. I'm
sure that there are some cruisers out there who would find the cost of
one of these cats a whole lot cheaper when they factor in their diesel
usage over a few years.
