The main sail of the fiberglass J/24 keelboat coursing through bay waters just off Treasure Island flitted in the wind with a nervousness that told 2016 Olympics mariner Caleb Paine what was coming next.
He pointed to dark choppy waters ahead, called for his novice passengers to scurry over to the windward side and began counting down: “Five, four, three, two … .”
With a snap, the sail filled like a massive lung, shooting the vessel forward, past a fleet of kayakers and cormorants ducking their heads below the surface. His passengers cheered.
“Nothing beats being on the water,” Paine called out.
San Francisco Bay is a roughly 500-square-mile ecosystem, a thoroughfare for commuter ferries and marine life where fresh water coming down from the Sierra and Pacific Ocean saltwater mix and swirl.

But for 24 years, the Treasure Island Sailing Center has tried to shake that image and get more people onto the water. The nonprofit brings roughly 3,000 children each year through school and summer programs onto boats to learn this watery world is theirs, too.
“I was spellbound,” said Neerja Sundar, 29, marveling at the sea level view of San Francisco’s stunning skyline as she paddled a kayak.
Saturday, the center hosted its annual open house, giving people free tours on sailboats or kayaks. Hundreds lined up by noon. Coast Guardsmen fitted children with free giveaway flotation vests. Sailing center volunteers zipped adults in loaner vests.
Volunteer Neha Bazaj — a sustainability nonprofit worker from Oakland who races a small dingy called a Vanguard on weeknights — held a clipboard and a large stuffed unicorn left behind by a 3-year-old out on the water with her family for the first time. Bazaj, 34, caught the sailing bug while a student at UCLA, and on Saturday explained the difference between fleet racing and team racing — one involves “messing with other boats” by taking advantage of wind patterns and other maneuvers, she said with a wink.

Yalonda M. James/The ChronicleToddler Bahia climbed out of a boat and up the plank to reclaim her unicorn. Her mother, Giza Anarbeava, gasped at their “fantastic” sail, something she said they would not have done without this free experience.
The event was meant to bring people from throughout the Bay Area to a place they may not be able to go otherwise, said Doug Paine, the center’s executive director. The organization focuses on children from low-income communities for its school programs and offers scholarships during the summer.
The center’s teachers train children in critical water safety skills, like what to do when a sailboat capsizes. They also offer science lessons alongside basic sailing skills. Paine said the organization aims to imbue children with a sense that the world might be bigger with more opportunities than they thought before setting sail. And maybe a few, hopefully, will become lifelong mariners.
Malik Brown, 48, a mentor through nonprofit Friends of the Children brought 11-year-old Jing Teng and his grandfather out on the water Saturday. Teng marveled at the vessel’s below-deck quarters that “looked like a home.” His grandfather, who introduced himself as Mr. Lui, said he used to sail decades ago on rivers where he grew up in China.

Yalonda M. James/The Chronicle“We talked about (polluting) emissions and how this is a way to get around that doesn’t use gasoline,” Brown said.
El Cerrito third-grader Logan Toomey, 8, was excited to sail because he loves the Disney movie “Moana.” His grandmother, Connie Farris, hadn’t sailed in more than 10 years and missed being out on the water.
Stonly Blue, 38, stared out at the water holding his 15-month-old son, Sire. Blue had promised his wife he wouldn’t take their toddler on a boat — not just yet — but couldn’t resist the desire to come observe from the dock. So the pair set out Saturday morning hopping on two buses from their San Francisco apartment to Treasure Island.
“I’m hoping he’ll say the word ‘boat,’ ” he said.
