A new concept vessel is combining diesel-electric
hybrid technology with renewable solar energy and
a high-capacity battery, resulting in a clean, quiet,
safe and more enjoyable boating experience.
The boat is a project of Mercury Marine, Cummins’
joint venture partner for marine propulsion using
Cummins diesel engines 15 liters and smaller.
The boat reduces energy consumption by
using solar power to recharge the lithium
ion batteries and advanced automatic
control strategies for optimal efficiency.
The environmental benefits include cleaner
air and water and greenhouse gas reduction
through better fuel efficiency and the use of
renewable energy.

The hybrid propulsion combines reliable diesel
engines and electrical systems so they can
operate together or independently, providing
built-in backups. Solar power is independent
of shore power and provides electrical backup
to bilge pumps, starting batteries and other
critical components.
This new technology was shown at the Miami
International Boat Show earlier this year to
positive reviews.
