"When I was looking to purchase a boat the first thing I wanted to do is find a company that I felt comfortable with, so I looked around at a few different builders. I knew I wanted an aluminum boat, and I knew that I wanted a cat. I’ve owned a cat before, so I know how stable they are and that’s what I was looking for. When I visited ACI, and I met everyone, one of the first impressions that I got was that they’re super family oriented. They don’t treat you like just another customer, they treat you like family. Obviously the quality of the boat is the most important thing. They really take pride in their boats, and the quality of their work.

This boat is the best of both worlds. It has plenty of cabin space, and plenty of cruising space. I wanted a boat that could be out on the water for 5-6 days and not have to return back for any reason. This boat will do that hands down, no problem, in any weather and be safe and comfortable. Comfort and fishability were the most import things to me. My opinion- hands down, this boat gives you the best of both worlds that no other boat has. Overall this boat is a 10/10 for me."

"Working with ACI has been a first-class experience. From the design, build, and final logistics of transporting the boat across country in the middle of a pandemic, they made it a smooth process with wonderful results. We had considered moving a boat in town to use as a water taxi for sometime and with COVID that really accelerated the idea. We contacted several boat builders, some that we had used in the past, but really felt comfortable working with ACI even though they were on the other side of the country. As far as the final product, we are very pleased. We were able to use it offshore for a few days when it first arrived and it handled some rough conditions well, given its size. Once we moved it in town as it was designed for, it has shined. The fuel economy and speed benefits for our operation are already showing. Jobs that we wouldn’t have made before are now getting covered and we are not having to call as many people in during their time off. Wake complaints from our larger boats are gone as well, one of the most important aspects for us given the amount of recreational watercraft in the area.
We look forward to working with them again on future builds.

As an owner of a newly constructed ACI Boat, I'm impressed with their ability to overachieve on expectations. Throughout the whole process, Cory Armstrong and his crew were accommodating to my input and concerns. The final product is a charter boat thatI'm proud to take clients on knowing their comfort and safety is forefront on design and execution. Thank you everyone at ACI!

We deal with quite a bit of weather as we operate daily in the open Gulf of Alaska and I am thoroughly impressed with how she handles a rough sea. Just the other day I was in a 10', 30 knot sea state and was able to maneuver our 36'x13' Lumacat safely, and surprisingly comfortably back to port.
