Student Boatbuilders

Students in NYC learn to build their own boats—and sail them!

Students sail their finished boat on the East River in New York City.

Last year, seventh-grader Dana Garcia guided her class’s sailboat, called Pizza Sail, onto the East River in New York City. The view couldn’t be beat: Dana could see almost all of the city skyline.

For Dana, the outing was special for another reason too. She and her classmates at Middle School 88 in Brooklyn built Pizza Sail themselves.

Students at M.S. 88 assemble parts for their boat.

For more than 10 years, an organization called Brooklyn Boatworks has been teaching kids how to build boats. It transforms classrooms into workshops. Students saw, drill, and mold pieces of wood to make a boat. 

Dana and her classmates built a model of boat called an Optimist Pram, or Opti for short. They met once a week after school.

Students cut each piece of the Opti from plywood sheets. The team assembled the pieces. Then adults waterproofed the boat. After eight months of effort, every student who worked on the boat sailed it — after some sailing lessons, of course!

Pizza Sail wasn’t Dana’s first boat project, and it won’t be her last. “Once you start building, you’ll learn more and more,” she says. “It’s amazing seeing what you can accomplish.”

Dana and her classmates built a specific model of boat. That model is called an Optimist Pram. It’s also called an Opti. The classmates met after school. They met once a week.

On an Opti, the post that the sails attach to is called the mast. Students cut out pieces of wood for a mast thwart, a structure that supports the mast. One half of the mast thwart is roughly this shape:
