The NMTA is the country's largest regional marine association. Founded in 1947, the Association quickly expanded its vision of a unified industry by pitching a tent on the shores of Lake Union and holding its first boat show. Today, NMTA represents more than 600 companies in the recreational boating business, including boat dealers, boat brokers, marinas, boatyards, boat and boating accessory manufacturers, retailers and suppliers of boating accessories and services. The NMTA produces the Seattle Boat Show, the West Coast’s Largest Boat Show, each January, as well as numerous other events such as the Northwest Salmon Derby Series through NMTA's regional self-funded Grow Boating program. Northwest Marine Trade Association Mission Statement: The purpose of the Northwest Marine Trade Association is to promote the growth of recreational boating and the businesses of our members.
