A.F. Theriault & Son Boat Builders

Where Tradition and Innovation Meet

A.F. Theriault & Son Ltd. is one of the largest, privately owned boatyards in Canada's Atlantic region. This family owned and operated business was founded in 1938 by Augustin Theriault in an era when wooden boats still ruled the seas. Today, the yard is a very different place, building state-of-the-art workboats, pilot boats, patrol vessels, yachts, fireboats and passenger ferries.  We pride ourselves at being very innovative in combining old techniques with the latest materials and technologies to build boats of the highest quality from steel, aluminum, fiberglass and advanced composites.

Our indoor production facilities for vessels up to 150 feet in length demonstrate, through outstanding quality, performance and reliability, a personal dedication to our clients and pride in our workmanship. Our production staff includes over 150 highly trained professional boat builders, including professional engineers, tradespersons, project administrators as well as support staff, all of which contribute to the continued success and growth of A. F. Theriault & Son Ltd.  We continually invest in our staff through training and certification, as well as participating in apprenticeship programs for new employees.

A.F. Theriault places a strong emphasis on construction quality, safety and stability of all boats and builds and repairs in accordance with Transport Canada Marine Safety (TCMS), US Coast Guard and American Boat and Yacht Council (ABYC) as well as to class requirements such as Lloyd's Register, Det Norske Veritas and American Bureau of Shipping (ABS).
