The Workhorse of the Water

The Sherpa is built for one purpose: getting the job done, no matter the conditions. With its rugged aluminum landing-craft design, walk-around cabin, and 80” bow door, the Sherpa is the ultimate multi-mission platform. Whether it’s transporting crews and materials for waterfront construction, serving aquaculture farms with feed and gear, or supporting enforcement and port operations, the Sherpa delivers the power, payload, and reliability professionals demand.
Designed in collaboration with operators and optimized for electric propulsion, the Sherpa is as versatile as it is durable. Outfitted with Photon Marine’s high-performance outboards, it becomes a clean, quiet, and cost-effective alternative to diesel or gas fleets — without sacrificing performance.
Available now with CARB/CORE and WAZIP vouchers, customers can receive substantial incentives to cover the cost of electrification — making the Sherpa not only the toughest boat on the water, but also the smartest investment.
