Grace Quan is a modern reconstruction of a Chinese-American shrimp fishing junk, similar to those in the fleet that operated in San Francisco Bay in the late 19th and early 20th centuries. The junk was built in 2003 as a joint project between China Camp State Park in San Rafael, California and the San Francisco Maritime National Historical Park, and is now jointly exhibited and operated by both institutions. It functions as a "working sailing museum" to educate the public about a previously forgotten chapter in the history of Chinese-American immigrants to California.
