Compo Beach is known as a place for great summertime cookouts, but even though the shoreline was boiling Saturday it had nothing to do with the sunny skies.

For the fourth year, the Westport Rotary’s LobsterFest brought a big crowd of crustacean-loving diners to the beach in the name of charity. Around 1,500 people attended the event, where music and sunshine made for an appetizing setting to enjoy lots of lobsters or steak.

“It’s a great community event,” said Peter Gillespie, Rotary secretary. “It’s has a little bit of the spirit of Westport to it, and it raises funds for all the local charities.”

“It’s a great thing all the way around,” he said.

Not one but two lobsters for the $50 asking price were served up — or steak if the diner preferred — along with corn, other side dishes along with beer and wine.

“You can’t beat it,” said Matt Brain, who traveled from Brick, N.J., to enjoy the Westport event. “This whole area is gorgeous, and it’s such a nice day.”

“I come every year,” said Wei Chen of Westport. “It’s just a great end of summer event, the last week of summer enjoyment.”

“This is a real community event,” said John Hartwell, one of 190 volunteers that gave time to see that the enormous crowd was cooked for, fed and cleaned up after. “In four years the Rotary has created, developed and established a fantastic community event.”

“We make a ton of money,” Hartwell said, “and it all goes back to local charities we support, and international charities.”

“And it’s a lot of fun,” he said, “so I have a good time doing this.”

According to Rick Benson, past district governor for Rotary, there were 2,400 lobsters prepared, along with 300 steaks and 150 kids’ meals, which included hot dogs and chicken tenders. “That’s enough for about 1,500 people,” he said, noting that while some 1,400 tickets were sold in advance, there were additional walk-ins.

“It’s a great community event,” he said. “We’ve got 1,500 people here. Lots of families. Lots of candidates running for office. Mostly Westporters, but people have their families here and kids from out of town.”

“And it’s a successful fundraiser to help Rotary do good in the community,” he said.

“It’s a lot of work, but it really is so much fun,” said Leslie Wolf, who helped to organize volunteers. “We have volunteers coming from New York City,” she said, as well as Westchester County and even New Orleans.

“And every volunteer buys a ticket, so they’re supporting the cause too,” she said. “It’s pretty amazing.”
