ACI Boats is a Port Townsend, Washington-based boatbuilder focused on aluminum vessels for maritime transportation, offering highly customizable catamarans and monohulls. The boats rely on a standardized hull design aimed at improving efficiency, performance, and safety, and are designed for owner operation, durability, comfort, and fuel economy. Led by Cory Armstrong, who has decades of experience in aluminum boat construction—particularly catamarans—the company relies on a skilled team of engineers, designers, welders, and craftspeople. The firm continually updates hull designs to incorporate current propulsion options and to respond to client needs. Its customers include maritime transportation operators, particularly commercial fishing outfits and work-boat clients, with examples such as Bristol Bay gillnetters and CatLander landingcraft. In early 2025, the company participated in the Pacific Marine Expo in Seattle to showcase a 32-by-16.5-foot aluminum gillnetter and demonstrate onboard capabilities.
