Have it all. Performance. Comfort. Durability. Impressive value.


ACI Boats builds all welded aluminum catamarans and monohulls. Available in two standard lines or as custom builds, our boats combine the durability and practicality of commercial aluminum boats with designs that provide comfort and high performance. Each boat is meticulously handcrafted and every detail scrutinized by our skilled craftsmen to ensure that we meet the highest quality standards. Rest assured, your ACI boat will provide trouble-free enjoyment and performance for years to come.


It's easy to see why ACI's standard series boats are so popular.


Clients who choose a boat from our Montague or Lumacat series are able to enjoy the amenities of a custom boat while saving in design and construction costs. Choose your own finishes and details while enjoying confidence in the proven performance of existing boats. This flexibility allows for each boat to be unique, although the starting design is an existing model. Boating enthusiasts that do not have the time and capacity to be directly involved in a fully custom project will find that our existing models are an easier solution at a lower price. In addition, they're available for a  faster delivery while still offering the opportunity to create very personalized vessels.


Recreational Boats


If you have your sights set on daytime adventures and relaxing evenings, you'll love ACI Boats' lineup of recreational vessels. These boats are a seamless blend of the ruggedness and durability of traditional all welded aluminum commercial boats with the comfort and convenience that recreational users have come to expect. All vessels offer a complete list of standard features as well as a generous menu of options to personalize the boat exactly to your own liking.


Commercial Boats - Rugged and Refined


ACI Boat’s commercial boats are engineered to combine durability and power with amenities to meet the business needs of our clients. Constructed of strong and lightweight all welded 5086 aluminum, each vessel is built by hand to CWB standard W47.2 for fusion welding of aluminum. These boats are designed and built to be tough. Really tough. They’re going to give their owners years of value with minimal upkeep.


You’ll appreciate the comprehensive list of standard equipment as well as the options available to customize the boats. Charter captains will appreciate the amenities these vessels offer to keep their clients entertained and comfortable, and the easy to clean surfaces make it easy to keep the boat looking good.


On the off chance that you don’t see exactly what you’re after in one of our standard series please give us a call to discuss the option of a custom built boat. We’d love the opportunity to work with you.


Alaska-Tough MonohullsACI Boat's Montague series is a line of aluminum monohulls that are as rugged as the waters they’re designed to conquer. Featuring an assertive design and an impressively smooth ride, Cory Armstrong has designed the series to combine the practicality of commercial boats with the comfort of recreational designs. The results are an irresistible blending of power, comfort, durability and value. Built for both the recreation and commercial markets, the Alaska series is available in lengths from 29' to 43' and each in either our walk around Sport cabin or our full width Cruiser cabin with or without a cuddy.. 

Ocean Class
Catamaran enthusiasts love the Lumacat series, ACI Boats' high-speed, ocean class catamarans. Their long and narrow hull offers increased efficiency and lower fuel costs. Recognized for their stability, catamarans have a more comfortable ride than monohulls with the feeling of a larger craft and a softer ride. In addition, catamarans are typically wider than a conventional monohull and have good use of below-deck hull space for berthing and other amenities. Lumacats are currently available in five model lines, ranging in lengths from 28' to 54' and each in either our walk around Sport cabin or our full width Cruiser cabin with or without a cuddy.
