Silverback Marine is a U.S. boat manufacturer based in Tacoma, Washington, that specialises in custom aluminium workboats, landing craft, patrol boats and commercial vessels — with a growing focus on full-electric and hybrid propulsion. Since its founding, Silverback has pursued a “co-design with the customer” model, bringing together rugged durability, advanced design and zero-emission options.

Here’s a breakdown of what Silverback Marine is about:

Overview

• Name: Silverback Marine

• Founded: 2020

• Headquarters: Tacoma, Washington, USA

Technology & Design

Silverback Marine utilises advanced aluminium hull construction for strength, durability and light weight. Their “co-design with customer” approach means end-users participate in the design process from concept to build. Electric variants integrate large battery systems and electric outboard or inboard drives aimed at quieter, cleaner operation. In sensitive environments (marine protected areas, ports, operations near marine wildlife) Silverback’s electric vessels offer a value-proposition in reduced noise, zero fuel/oil emissions and lower lifecycle maintenance.

Sustainability

Traditional diesel workboats emit significant greenhouse gases, fuel/oil pollution and high noise levels. Silverback Marine addresses this by building full-electric versions of its workboats, delivering zero tailpipe emissions, substantially lower noise (critical for marine mammals and protected waters) and no oil/fuel spills. Their electric workboat for the Port of Lopez Island is an example of this transition. 

Vision

Silverback Marine aims to transform the workboat and commercial boat industry by proving that aluminium-built, electric-ready vessels can serve the toughest operational missions while reducing environmental impact and running cost. They want to make the shift toward clean-marine durable platforms normative for government, port, research and enforcement clients.
