a Workboat that works


The Silverback Grizzly workboat has fought hard over the years to establish its reputation as the "workhorse of workboats". One ride on this stable, high-payload, controllable platform is all it takes to believe. Outfitted with the all-electric Photon P300 with a 63kWh battery pack, the Grizzly is ready for heavy duty commercial applications.

From ports to utility companies to water quality monitoring, the Grizzly is at home in the salty waters of the Puget Sound to the freshwater rivers and reservoirs on the east coast. It can be charged overnight on 240V / 50A power, or within 40 minutes using a level 3 charger.
