Boat Building, repair, refit and conversion.

The boat building and repair industry has seen many changes and endured many challenges over the years. A.F. Theriault & Son has evolved right along with it. While we stress tradition and time-tested skills, we have not remained “stuck in the past”. We use modern techniques and materials to build the finest boats of their kind. We also take great pride in our boat repair, refit and conversion work, helping our clients get the very most from their existing boats.

In this new millennium, boats need to be state-of-the-art, regardless of their use, from pleasure yachts and catamaran workboats, to patrol boats and fishing trawlers.  We combine old techniques with the latest developments and technologies, building boats of steel, aluminum, fiberglass and composites.

Our commercial and recreational vessels with lengths up to 150 feet (45m) demonstrate, through their obvious handling performance and build-quality, a pride in workmanship and dedication to our craft. Our boatyard employs over 150 workers, who are well trained as professional boat builders. From our boat builders and tradespeople to engineers, researchers and administrators, we know that our people are the key to our success.

The construction quality, safety and stability of our vessels are a priority and we operate in strict accordance with rulings passed by TCMS, ABS, Lloyd's and Det Norske Veritas.
