When Isabella Calzadilla first arrived to set sail in the bay off Long Beach Island, she openly wondered about something and had no qualms about questioning it.

“I asked, ‘Why’s the water green and am I going to die in there?’ The water is much clearer in Puerto Rico,” said the 11-year-old from San Juan, who has sailed at Surf City Yacht Club while visiting her grandparents in Manahawkin each summer for the past six years.
