A year-long project to repower Riverboat Angela Louise to DC electric has been completed, said Captain Joseph Warren. Now, the 100-passenger, USCG-certified turn-of-the-century riverboat nearly completely abandons conventional diesel propulsion and on-board power, for clean, efficient electricity. Captain Warren explains it as revolutionary: "Diesel exhaust contains 41 constituents listed under California Prop 65 guidelines as Toxic Air Contaminants. The particles and chemicals emitted from diesel are overwhelmingly dangerous. In our fragile marine environment in Newport, where the sea water turns over infrequently, these contaminants remain and find there way in the ecosystem, damaging wildlife and people, alike.
