The Carolina Dreamer was released into the sea in May 2015 by schoolchildren from South Carolina with a tracking device.
The class were able to follow the boat's 4,000 mile journey across the Atlantic Ocean.
Now they're hoping it might make it back to America from Wales.
A family found a boat washed up on a beach in Wales which had been launched by a school in America.
