The National Marine Manufacturers Association said registrations of new powerboats were up 6.1 percent year over year for the rolling 12-month period through July.

The NMMA said all boat segments improved through July, but the growth was led by jetboats (up 10.9 percent); tow boats (up 9.5 percent); personal watercraft (up 9.4 percent); pontoons (up 7.7 percent); cruisers (up 7 percent); and saltwater fishing boats (up 6.8 percent).

Registrations of outboard-powered boats were up 5.5 percent. Outboards represent 65 percent of new powerboat sales.

Registrations of boats 27 feet and larger were up 10.3 percent.
