About ACI Boats – Aluminum Catamarans & Monohulls

Owner/Founder of ACI Boats, Cory Armstrong

ACI Boats is a boat building company and we love what we do.

It’s who we are.

CORY ARMSTRONG (resume) founded ACI Boats to build welded aluminum vessels that are high speed and low maintenance.

Our boats are ocean class and blend the durability of commercial boats with the comfort demanded in the recreational market. Our goal at ACI is to design and build great boats that deliver both performance and value. By following a standardized production process we efficiently produce a high quality aluminum vessels. 


Follows the automotive industry model

Typically, consumers desiring a high-end aluminum boat hire an engineer or naval architect to develop a design, then contract with a boat yard to build the custom vessel, a process that is both expensive and time-consuming. Under ACI Boats, Cory Armstrong has designed monohulls and catamarans following the automotive industry model — offering standardized boats with a generous menu of finish options.

All ACI’s boats are designed for the owner-operator and provide high end performance, passenger comfort, fuel efficiency and durability.

Our monohull and catamaran boats provide high quality designs to clients with individually chosen custom finishes. Depending on the model, boats are available in three trim levels so buyers can choose upholstery, finishes and paint colors.

Our monohull and catamarans are custom designed and built for clients who want a totally unique design.
