In Sausalito, California, 150 volunteers are constructing a traditional wooden tall ship based on a 1891 design. The documentary, filmed over three years by volunteers, is in 3D. All proceeds will be donated to the completion of the ship. The new brigantine, when launched in 2017, will be operated by a non-profit, the Call of the Sea, who has been successfully running on-the-water learning programs for 30 years.
