New powerboat sales increased 5 percent in 2017, to 262,000 units, the highest level the boating industry has seen in 10 years.

Total marine expenditures on new boats, engines, trailers, accessories and services were at an all-time high last year, at $39 billion, up 7 percent over 2016, according to new data from the National Marine Manufacturers Association’s 2017 Statistical Abstract.

Boatbuilders are expanding capacity to meet demand, with new plants and increased production.

That supports recent data from the Bureau of Economic Analysis that U.S. manufacturing’s gross output increased to $6.228 trillion in the fourth quarter of 2017.

“As the strong economy continues to bolster new-boat sales and boating expenditures, capital spending and manufacturer optimism are at record highs, creating one of the strongest periods on record for the U.S. boating industry and a buyers’ paradise, with more boats and more options on the market,” said NMMA president Thom Dammrich in a statement.

“Economic factors such as an increase in GDP, improving housing market, strong consumer confidence and growing disposable income are spurring demand for new boats,” Dammrich said. “The growth trajectory recreational boating is continuing to see is healthy and steady as the industry works to bring new buyers to the market across all segments, from small aluminum fishing boats to large cruising yachts.”

Sterndrive cruisers between 22 and 32 feet rebounded to a three-year high, up 5 percent from 2016, accounting for 52 percent of all sterndrive-boat sales.

Outboard-boat sales — representing 85 percent of new traditional powerboats sold, including pontoons, aluminum and fiberglass fishing boats, and small fiberglass cruising boats — were up 5 percent in 2017.

Sales of new ski and wakeboard boats were up 8 percent in 2017; new personal watercraft sales, considered a gateway to boat ownership, rose 5 percent; and jetboats saw a sales increase of 8 percent.
