Leading the way were boats larger than 27ft, up 11.9%. Among these, growth was led by saltwater fishing boats, which were up 17.2%.

Cruisers, tow boats and outboard-propelled runabouts were up 8%-9%, while sterndrive cruisers, personal watercraft, pontoons, yachts, saltwater fishing boats and freshwater fishing boats were up 3%-4%.
