NORTH FORT MYERS, Fla. -- The wind was calm, but the competition was fierce on the Caloosahatchee River Saturday.
Around 340 kids, from ages 8 to 17, sailed the seas as part of the Edison Sailing Club's Annual River Romp.
And as their sails go up this weekend, so do the sales for local business.
"Unmistakably helpful. When you're packed from open to close the whole weekend, at this time of year, you know something special is going on," said John Browning, who owns 3 Fisherman Seafood.
The grill takes in thousands more than they would on any other weekend this time of year.
"Thousands, the hotel here, Best Western is sold out. Parking lots are packed, streets are overwhelmed as you can see," said Browning.
A manager for Best Western says their 108 rooms sold out in about two months, and they're already close to filling up for next year.
The Edison Sailing Club pushes local too, handing out maps of the city to all who come.
John Yarborough says they've never had this many boaters before, and because they don't show up alone, it's easy to see why business booms.  
"This is a event the parents go to. They don't ship them off. You know mom and dad. Lot of grandparents here, so it's a big number."

The Romp will continue Sunday at 8:30.
