The 2015 Progressive Insurance Baltimore Boat Show, which expanded 20 percent this year to accommodate industry and consumer demand, closed Sunday, reporting an increase in attendance of 17 percent.

The National Marine Manufacturers Association said 13,752 people attended the four-day show at the Baltimore Convention Center and several exhibitors reported meeting with new customers and generating sales that surpassed the 2014 event.

“We sold two boats on opening day. We are really happy with attendance,” said Andy Lease of Taylor Marine/Grady-White. “It was an unbelievable Saturday. We have talked to so many people and made sales we were not expecting to make.

This show was the best show in years,” said Al Marinelli of Almars Outboards.
