Gary Chouest, who founded the Galliano shipyard Edison Chouest, has led a group that purchased Westport Shipyard Inc., a Washington company that is one of largest yacht builders in North America.

Westport LLC, a group that included Chouest and members of his family, acquired the shipyard. Terms of the sale were not disclosed.

Along with Edison Chouest, the Chouest family also owns American Custom Yachts, of Stuart, Florida.

Westport has three shipyards in Washington state and a marina and sales office in Fort Lauderdale, Florida. The company, which has more than 400 employees, has built more than 120 yachts since 2000. The company’s yachts cost several million dollars.

“Similar to the history of the Chouest family business, Westport began five decades ago with a fishing fleet and has diversified into many other core businesses, focusing on customer satisfaction and the pursuit of excellence,” Chouest said.

Chouest said he looks forward to pursuing synergies that exist among Edison Chouest, American Custom Yachts and Westport.

“We will continue to pursue the employment of skilled local workers and will remain an active participant in the communities Westport serves,” Chouest said.

“Gary (Chouest) has always been passionate about our industry, and we are honored to count him as a customer and now our majority owner, as well,” said Daryl Wakefield, Westport’s president, who will remain in that position, along with the rest of Westport’s management team and employees.
