much as 10% savings in fuel during transit in heavy seas. • Silent Vessel: Imagine cruising into a noise sensitive area with no engines running; for example, whale watch- ing, scenic fjord cruises, scienti? c operations, and seismic operations. The opportunity to operate a vessel for several hours with no engines running still promises many as yet unexplored opportunities. • Redundancy: With batteries on board, not only one more power source is made available, a completely differ- ent energy source from the combustion engines opens up other possibilities and advantages. This is something that could bene? t such hazardous missions such as ? re? ghting and gas terminal support craft. • Less Expensive Fuel: Finally, electricity – dependent on the source and local economic models – can be less expensive than running diesel engines. It does not pollute locally, and it does not pollute globally if the power is gen- erated from clean power.

In short, batteries represents multiple ways to reduce running hours dramatically for virtual any vessel type, ultimately minimizing expensive service intervals, saving fuel and myriad other jobs on engines. The concept has legs, and is in use right here in the United States. This year, All American Marine and Red and White Fleet of San

Francisco announced the launch of the Enhydra, the new- est member of the R&W passenger excursion vessel ? eet.

The 128-foot LOA aluminum monohull vessel with a 30- foot beam is the largest lithium-ion battery electric hybrid powered vessel in North America built under “USCG Sub- chapter K” certi? cation.

The propulsion integrator or the 600-passenger vessel is BAE Systems, who supplied their HybriDrive propul- sion system that includes a generator, propulsion power converter, house load power supply and control system.

No doubt more of these kinds of vessels are on the way. It might even be a good ? t for your operations.
