Last year's Head of the Hooch generated millions of dollars for the local economy and with another full day of races Sunday, this year is expected to bring in the same if not more.

Ten thousand plus, that's the number of competitors in this year's rowing regatta, one of the largest crew races in the nation.

More than 2,000 boats hit the water and with each paddle stroke local businesses saw dollar signs.

"This regatta has now become a three or four day event with folks coming from 34 different states to stay in Chattanooga for two or three days and night here in the city," Assistant Race Director Doug Beville says. 

One riverfront restaurant owner says Saturday's business was record breaking. "I know that most the other restaurants had waiting lines to get in all day yesterday and I know I had to make a reservation to get my dinner tonight," Beville laughs.

Since the Hooch settled in the Scenic City it has nearly doubled in size. Last year's race netted $4.8 million in revenue for Chattanooga. While officials can't say yet how much of an economic impact this year's race will have one thing is for sure, the Head of the Hooch isn't going anywhere anytime soon.
