LEE COUNTY, Fla. -- The U.S. Coast Guard says Blind Pass is one of Southwest Florida's beaches prone to dangerous currents.

A group of swimmers found that out the hard way Thursday afternoon.

"They got caught out on it, and they were holding onto a boogie board when our crews got out there," says Greg Mattson, with the U.S. Coast Guard.

Rescuers fished out seven swimmers -- 2 adults, plus kids -- hundreds of yards out at sea. They were safely brought to shore, and no one was injured.

Near Blind Pass, the stretch of waterway between Sanibel and Captiva Islands, signs warn beach-goers of potential danger though most feel comfortable taking their chances.

"When you get close to the rocks you can feel it pulling," says Tina Bertino, who was wading through the water Friday afternoon.

Mattson says they get quite a few rip current calls, 2 to 3 a week during the busy tourist season. He says the majority come from the area between Blind Pass and Boca Grande Pass.

"The tidal changes and currents in there are a lot stronger than some of our passes down south," Mattson says.

In May, a 65-year-old North Port man drowned when strong currents carried him out into the gulf at Boca Grande.

While Mattson says it's hard to predict when a strong current is coming, if you are caught in one, he says not to fight it.

"You're fighting against all that current that's coming out, and you'll just tire yourself out, so just swim parallel to it until you get out of that rip," Mattson says.
